Introduction to the project

1.1Introduction

MySQL is a relational database management system (RDBMS) that runs as a server providingmulti-user access to a number of databases.

The official MySQL Workbench is a free integrated environment developed by MySQL AB, that

enables users to graphically administer MySQL databases and visually design database structure.

MySQL Workbench replaces the previous package of software, MySQL GUI Tools. Similar toother third-party packages but still considered the authoritative MySQL frontend, MySQL

Workbench lets users manage the following:

Database design & modeling

SQL development replacing MySQL Query Browser

Database administration replacing MySQL Administrator

Linux (commonly pronounced LIN-ks in American-English also pronounced in Europe and

Canada, LIN-ooks is a generic term referring to Unix-like computer operating systems based on the

Linux kernel. Their development is one of the most prominent examples of free and open source

software collaboration; typically all the underlying source code can be used, freely modified, andredistributed, both commercially and non-commercially, by anyone under licenses such as the GNU

General Public License.

Linux can be installed on a wide variety of computer hardware, ranging from embedded devicessuch as mobile phones, smartphones and wristwatches to mainframes and supercomputers. Linux is

predominantly known for its use in servers; in 2007 Linux's overall share of the server market was

estimated at 12.7% while a 2011 estimate suggested that 60% of all web serversran Linux. Mostdesktop computers run eitherMac OS X orMicrosoft Windows, with Linux having only 12% of

the desktop market. However, desktop use of Linux has become increasingly popular in recent

years, partly owing to the popularUbuntu distribution and the emergence ofnetbooks and

smartbooks.

Project plan

4.1 Team Structure

The team structure for the project is guided by Mr Dhananjay Tiwari. Proper session under his

guidance is established for the requirements and need on the users side as well from the developers

side

It was guided and supervised by the project guide on weekly basis.

4.2 Development Schedule

The following steps were followed in developing the application:

1. Study, Analysis and Requirement Specifications: The study of the existing system and its

drawback gave an idea about what kind of interface was required. The study was conducted

through information gathering and studying the existing system.

2. Design of the proposed system: The next step was to design the screen, windows and

reports for the inputs and outputs. The concerned authorities consulted during the design

phase to ensure user acceptances and not to miss out on any vital information. In the same

phase, the project was broken down into various modules.

3. Coding of the design system: A modular approach was followed, where, in each module,

a well-defined procedure was developed independently. These modules were developed to

use the same database file structure to ensure integrity.

4. System documentation: This stage consists of documenting the layout of entire system. It

indicated the purpose of interlinking of different modules along with the integration of theentire system.

5. Testing and Debugging: Preliminary test were done with the self-generating dummy data.

After identifying and removing errors, it was tested for all activities together.

4.3 Programming Languages

The website is developed to the users point of view using hardware and software components that

required supporting the site is designed. The selection of the software for the designing the

application is important and it depends upon the requirement. After analysis various languages, andtools are selected which are discussed as follows:

4.3.1 HTML

HTMLis a computer language devised to allow website creation. These websites can then be

viewed by anyone else connected to the Internet. It is relativelyeasy to learn, with the basics being

accessible to most people in one sitting; and quitepowerfulinwhatit allows you to create. It is

constantly undergoing revision and evolution to meet the demands and requirements of the growingInternet audience under the direction of the W3C, the organization charged with designing and

maintaining the language.

The definition ofHTML isHypertext Markup Language.

Hypertextis the method by which you move around on the web by clicking on special text

calledhyperlinkswhich bring you to the next page. The fact that it is hyperjust means it is not

linear i.e. you can go to any place on the Internet whenever you want by clicking on links there is

no set order to do things in.

Markupiswhat HTML tagsdo to the text inside them. They mark it as a certain type of text.

History of HTML

HTML developed a few years ago as a subset of SGML (Structure Generalized Mark-up

Language), which is a higher-level mark-up language that has long been a favorite of the

Department of Defense. Like HTML, it describes formatting and hypertext links, and it defines

different components of a document. HTML is definitely the simpler of the two, and although they

are related, there are few browsers that support both.

Because HTML was conceived for transmission over the Internet (in the form of Web pages) it is

much simpler than SGML, which is more of an application-oriented document format. While it's

true that many programs can load, edit, create, and save files in the SGML format (just as many

programs can create and save programs in the Microsoft Word format), SGML is not exactly ideal

for transmission across the Internet to many different types of computers, users, and browser

applications. HTML is more suited to this task. Designed with these considerations in mind, HTML

lets user, the designer, create pages that user are reasonable, sure can be read by the entire

population on the Web. Even users who are unable to view user graphics, for instance, can

experience the bulk of what user are communicating, if user design, user HTML pages properly.

At the same time, HTML has a simple enough format (at least currently) that typical computer

users can generate HTML documents without the benefit of a special application. Creating a

WordPerfect-format document would be rather difficult by hand (including all of the required text

size, font, page break, column, margin, and other information), even if it weren't a "proprietary"

that is, nonpublic document format.

HTML is a public standard, and simple enough that user can get through a book like this one and

have a very strong ability to create HTML documents from scratch. This

simplicity is part of a trade-off, as HTML-format documents don't offer nearly the

precision of control or depth of formatting options that a WordPerfect- or Adobe

PageMaker-formatted document would.

Advantages of Html

Easy to use

Loose syntax (although, being too flexible will not comply with standards) Supported on almost every browser, if not all browsers.

Widely used; established on almost every website, if not all websites.

Very similar to XML syntax, which is increasingly used for data storage

Free - You need not buy any software

Easy to learn & code even for novice programmers

4.3.2 Cascading Style SheetsCSS is a style sheet language used to describe the presentation semantics (that is, the look and

formatting) of a document written in a markup language. Its most common application is to style

web pages written in HTML and XHTML, but the language can be applied to any kind of XML

document, including SVG and XUL.CSS is designed primarily to enable the separation of

document content (written in HTML or a similar markup language) from document presentation,

including elements such as the layout, colors, and fonts. This separation can improve content

8/3/2019 1my Report (2)

16/34

RIET Phagwara

accessibility, provide more flexibility and control in the specification of presentation

characteristics, enable multiple pages to share formatting, and reduce complexity and repetition in

the structural content (such as by allowing for table less web design). CSS can also allow the same

markup page to be presented in different styles for different rendering methods, such as on-screen,

in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based,

tactile devices. While the author of a document typically links that document to a CSS style sheet,

readers can use a different style sheet, perhaps one on their own computer, to override the one the

author has specified. CSS specifies a priority scheme to determine which style rules apply if more

than one rule matches against a particular element. In this so-called cascade, priorities or weights

are calculated and assigned to rules, so that the results are predictable.

Use of CSS

Prior to CSS, nearly all of the presentational attributes of HTML documents werecontained within

the HTML markup; all font colors, background styles, elementalignments, borders and sizes had to

be explicitly described, often repeatedly, within theHTML. CSS allows authors to move much of

that information to a separate style sheetresulting in considerably simpler HTML markup.

Headings (h1 elements), sub-headings (h2), sub-sub-headings (h3), etc., are defined structurally

using HTML. In print and on the screen, choice of font, size, color and emphasis for these elements

is presentational. Prior to CSS, document authors who wanted to assign such typographic

characteristics to,say, all h2 headings had to use the HTML font and other presentational elements

foreach occurrence of that heading type. The additional presentational markup in the HTMLmade

documents more complex, and generally more difficult to maintain.

In CSS,presentation is separated from structure. In print, CSS can define color, font, text

alignment, size, borders, spacing, layout and many other typographic characteristics. It can do so

independently for on-screen and printed views.

4.3.3 JavaScript

What is JavaScript?

JavaScript was first developed by Netscape as an open scripting language to create interactive web

pages. Script is nothing but a small program which is generally very easy to learn and

16 Amit Katyal(81411057005)

8/3/2019 1my Report (2)

17/34

RIET Phagwara

use. JavaScript as an open language implies that it can be used by anyone; no license is required to

use JavaScript. Microsoft created Jscript for its Internet Explorer similar to

Netscape JavaScript. JavaScript has the ability to function both as an object oriented language as

well as procedural language. Using JavaScript you can create objects, attach methods and

properties. Though JavaScript can run on both client-side and server-side, it is very popular among

client-side scripting languages. Client side means the script runs on client browser. JavaScript are

generally embedded in the header of web pages.

Why JavaScript?

JavaScript plays a vital role for adding interactive feature to HTML web pages. JavaScript can

respond to several events that occur on web-pages and thereby help in designing dynamic and

interactive web-sites. Moreover JavaScript makes it very easier to validate a form, check if any

fields are empty and verify correctness of data. JavaScript does all these at client side even beforeactually sending the data to server, thereby reducing considerable load on server and thus makes

form processing easier and quicker.

JavaScript can be used in different ways within an HTML file:

Head

In this type, JavaScript is embedded between tags within the tag and is

used for initializing variables and or create functions that can be called from anywhere of the

entire script. JavaScript in header is executed once when the page is load.

Body

In this type, JavaScript is embedded between tags within the tag.

JavaScript within Body Tags are used for handling various events.

Called directly when certain event occurs:

In this type, JavaScript are called when certain events occur. Example of events include on

Load, on Click, on Error, on Select, on Submit, on Change etc.

Advantages of JavaScript:

JavaScript offers numerous features which makes it popular. Few among them are listed

below:

JavaScript is a dynamic open scripting language with simple syntax and rules which makes

it easier to use and learn for programmers. This has made JavaScript a popular Client-side

scripting language. .

4.3.4 PHP

PHP stands for Hypertext Preprocessor and is a server-side language. This means that when a

visitor opens the page, the server processes the PHP commands and then sends the results to the

visitor's browser, just as with ASP. A typical PHP files will content commands to be executed in the

server in addition to the usual mixture of text and HTML (Hypertext Markup Language) tags.

However, PHP is Open Source and cross-platform. PHP runs on Windows NT and many UNIX

versions, and it can be built as an Apache module and as a binary that can run as a CGI.

PHP WEB SERVER

PHP was originally created by Rasmus Lerdorf in 1995 and has been in continuous development

ever since. The main implementation of PHP is now produced by The PHPGroup and serves as the

de facto standard for PHP as there is no formal specification.

When you type an URL in the Address box or click a link on a Web page, you're asking a Web

server on a computer somewhere to send a file to the Web browser on your computer. If that file is

a normal HTML file, it looks exactly the same when your Web browser receives it as it did before

the Web server sent it. After receiving the file, your Web browser displays its contents as a

combination of text, images, and sounds. In the case of a PHP page, the process is similar, except

there's an extra processing step that takes place just before the Web server sends the file. Before the

Web server sends the PHP file to the Web browser, it runs all server-side scripts contained in the

page.

PHP is a server-side scripting language for creating dynamic Web pages. You create pages with

PHP and HTML. When a visitor opens the page, the server processes the PHP commands and then

18 Amit Katyal(81411057005)

8/3/2019 1my Report (2)

19/34

RIET Phagwara

sends the results to the visitor's browser, just as with ASP or Cold Fusion. Unlike ASP or Cold

Fusion, however, PHP is Open Source and cross-platform.

PHP runs on Windows NT and many Unix versions, and it can be built as an Apache module and as

a binary that can run as a CGI. When built as an Apache module, PHP is especially lightweight and

speedy. Without any process creation overhead, it can return results quickly.

PHP WORKING

The Zend Engine is the internal compiler and runtime engine used by PHP4. Developed by Zeev

Suraski and Andi Gutmans, the Zend Engine is an abbreviation of their names. In the early days of

PHP4, it worked as

The PHP script was loaded by the Zend Engine and compiled into Zend opcode. Opcode, short for

operation codes, are low level binary instructions. Then the opcode was executed and the HTML

generated sent to the client. The opcode was flushed from memory after execution.

Process Benefits

Manage our content from anywhere

We can access all our information from a normal web browser - PHP is viewable in all kinds of

browsers, even mobile phone browsers. This means that we can manage our intranet and public

web site from a web browser anywhere in the worlds.

Live editingThe web site is updated from within the site itself - no specialized tools are needed,

just a web browser. It even works with older browser, so even if our organization does not use the

latest in web technology, PHP is still usable.

Designed by usability professionals

Because much care and thought has gone into the interface, employees will be able to utilize it with

minimal training. PHP use the standard paradigms for working with and controlling content.

Limited use of graphics

A main goal is minimal use of graphics - adding to the content instead of detracting from it, focusing

on the information - not irrelevant elements.

Facilities collaboration

When editing and publishing the content, we can assign other participants local roles within projects.

PHP also supports versioning and staging of contents.

Easy management and configuration

The administration and configuration of PHP is done through the web, and no access to the filessystem is needed after the system is set up. This makes for a very secure system.

Single sign-on

PHP has a centralized sign-on mechanism, which prevents users from having to log on to each area

separately. Security is controlled centrally. It is also easily integrated with the existing user

Create your own commands

Because PHP scripts sit inside HTML documents, you don't need a special editor to create pages. You

do need to be running on a server that supports PHP, however. If you run your own server, this is easy

enough to do. If an ISP serves your pages, contact your ISP's support team and ask that they install

PHP for you.

4.3.5 Ajax

AJAX = Asynchronous JavaScript and XML.

AJAX is a technique for creating fast and dynamic web pages.

AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with

the server behind the scenes. This means that it is possible to update parts of a web page, without

reloading the whole page.

Classic web pages, (which do not use AJAX) must reload the entire page if the content should

change.

Examples of applications using AJAX: Google Maps, Gmail, Youtube, and Facebook tabs.

4.4 Development tools4.4.1 MYSQL

MySQL, the most popular Open Source SQL database management system, is developed, distributed,

and supported by Sun Microsystems.

MySQL is a database management system.

A database is a structured collection of data. It may be anything from a simple shopping list to a

picture gallery or the vast amounts of information in a corporate network. To add, access, and

process data stored in a computer database, you need a database management system such as

MySQL Server. Since computers are very good at handling large amounts of data, database

management systems play a central role in computing, as standalone utilities, or as parts of other

applications.

MySQL is a relational database management system.

A relational database stores data in separate tables rather than putting all the data in one big

storeroom. This adds speed and flexibility. The SQL part of MySQL stands for Structured

Query Language. SQL is the most common standardized language used to access databases and

is defined by the ANSI/ISO SQL Standard. The SQL standard has been evolving since 1986 and

several versions exist. In this manual, SQL-92 refers to the standard released in 1992, SQL:

1999 refers to the standard released in 1999, and SQL: 2003 refers to the current version of the

standard. We use the phrase the SQL standard to mean the current version of the SQL Standard

at any time.

MySQL software is Open Source.

Open Source means that it is possible for anyone to use and modify the software. Anybody can

download the MySQL software from the Internet and use it without paying anything. If you wish,

you may study the source code and change it to suit your needs. The MySQL software uses the

GPL (GNU General Public License, to define what you may and may not do with the software in

different situations. If you feel uncomfortable with the GPL or need to embed MySQL code into a

commercial application, you can buy a commercially licensed version from us.

The MySQL Database Server is very fast, reliable, and easy to use.

If that is what you are looking for, you should give it a try. MySQL Server also has a practical set

of features developed in close cooperation with our users. MySQL Server was originally

developed to handle large databases much faster than existing solutions and has been successfully

used in highly demanding production environments for several years. Although under constant

development, MySQL Server today offers a rich and useful set of functions. Its connectivity,

speed, and security make MySQL Server highly suited for accessing databases on the Internet.

MySQL Server works in client/server or embedded systems.

The MySQL Database Software is a client/server system that consists of a multi-threaded SQL

server that supports different backend, several different client programs and libraries,

administrative tools, and a wide range of application programming interfaces (APIs).

We also provide MySQL Server as an embedded multi-threaded library that you can link into your

application to get a smaller, faster, easier-to-manage standalone product.

A large amount of contributed MySQL software is available.

It is very likely that your favorite application or language supports the MySQL Database Server.

The official way to pronounce MySQL is My Ess Que Ell (not my sequel), but we do not

mind if you pronounce it as my sequel or in some other localized way.

Advantages of MySQL

1. Scalability and Flexibility

The MySQL database server provides the ultimate in scalability, sporting the capacity to handle

deeply embedded applications with a footprint of only 1MB to running massive data warehouses

holding terabytes of information. Platform flexibility is a stalwart feature of MySQL with all

flavors of Linux, UNIX, and Windows being supported.

2. High Performance

A unique storage-engine architecture allows database professionals to configure the MySQL

database server specifically for particular applications, with the end result being amazing

performance results. Whether the intended application is a high-speed transactional processing

system or a high-volume web site that services a billion queries a day, MySQL can meet the most

demanding performance expectations of any system. With high-speed load utilities, distinctive

memory caches, full text indexes, and other performance-enhancing mechanisms, MySQL offers all

the right ammunition for today's critical business systems.

3. High Availability

MySQL offers a variety of high-availability options from high-speed master/slave replication

configurations, to specialized Cluster servers offering instant failover, to third party vendors

offering unique high-availability solutions for the MySQL database server.

4. Robust Transactional Support

MySQL offers one of the most powerful transactional database engines on the market. Features

include complete ACID (atomic, consistent, isolated, durable) transaction support, unlimited row-

level locking, distributed transaction capability, and multi-version transaction support where

readers never block writers and vice-versa. Full data integrity is also assured through server-

enforced referential integrity, specialized transaction isolation levels, and instant deadlock

detection.

5. Strong Data Protection

Because guarding the data assets of corporations is the number one job of database professionals,

MySQL offers exceptional security features that ensure absolute data protection. In terms of

database authentication, MySQL provides powerful mechanisms for ensuring only authorized users

have entry to the database server, with the ability to block users down to the client machine level

being possible.

6. Management Ease

MySQL offers exceptional quick-start capability with the average time from software download to

installation completion being less than fifteen minutes. This rule holds true whether the platform is

Microsoft Windows, Linux, Macintosh, or UNIX. Once installed, self-management features like

automatic space expansion, auto-restart, and dynamic configuration changes take much of the

burden off already overworked database administrators.

7. Open Source Freedom and 24 x 7 Supports

Many corporations are hesitant to fully commit to open source software because they believe they

can't get the type of support or professional service safety nets they currently rely on with

proprietary software to ensure the overall success of their key applications. The questions of

indemnification come up often as well. These worries can be put to rest with MySQL as complete

around-the-clock support as well as indemnification is available through MySQL Network.

4.4.2 Apache web server

The Apache HTTP Server is a web server for Unix-like systems, Microsoft Windows, Novell

NetWare, Mac OS X and other operating systems. Apache is notable for playing a key role in the

initial growth of the World Wide Web. When first released, Apache was the only viable open source

alternative to the Netscape Communications Corporation web server (currently known as Sun Java

System Web Server). It has since evolved to rival other Unix-based web servers in terms offunctionality and performance. Since April 1996 Apache has been the most popular HTTP server

on the World Wide Web; as of February 2007 Apache served 58% of all websites.

Apache is developed and maintained by an open community of developers under the auspices of

the Apache Software Foundation. Released under the Apache License, the Apache HTTP Server is

free software.

Analysis

5.1 Feasibility Study

Depending upon the results of the initial investigation, the survey is expanded to a more detailed

feasibility study. A feasibility study is a test of a system proposal according to its workability,

impact on the organization, ability to meet users needs and effective use of resources. Feasibility is

the determination of whether or not a project is worth doing.

Three key considerations are involved in the feasibility analysis, Economical, technical, and

operational. All of those are discussed one by one in the following section.

5.1.1 Technical Feasibility

Technical feasibility concern around the existing computer system and to what extend it supports

the proposed addition. In our case we have 1 server networked with the internet. Here a customer

requires minimum 1 computer with internet connection to run this project. So we can say that there

is no considerable burden on the organization to make this project functional .This is concerned

with specifying details and software that will successfully satisfy the user requirements.

Software requirements for this project at various abstractions are as follows:

MySQL, 5.0 or above is required as database server.

Apache Server and operating system must be Windows XP or higher.As all requirements are already available it is to invest anything in addition for the software.

5.1.2 Economic feasibility

Economic analysis is the most frequently used method for evaluating the effectiveness of the

candidate system. More commonly known as cost/benefit analysis, the procedure is to determine

the benefits and savings that are expected from a candidate system. And compare them cost. Since

cost plays quite an important role in deciding the new system, it must be identified and estimated

properly. Costs vary by type and consist of various distinct elements. Benefits are also of different

type and can be grouped on the basis of advantages they provide to management.

5.1.3 Operational FeasibilityPeople are inherently resistant to change. And computers are known to facilitate change. And

estimate should be made of how strong reaction the user staff is likely to have towards the

development of computerized system. The system should be simple to operate the layman can also

under stand what the system is, and how he can be benefited from the system.

The project is operationally feasible as every care has been taken to make it easy to operate and

more over while conducting preliminary investigations there was a strong reaction to open this type

of system from user side also.

5.2 System Requirement Specification

In system engineering and software engineering, requirements analysis encompasses those tasks

that go into determining the requirements of a new or altered system, taking account of the possibly

conflicting requirements of the various stakeholders, such as users. Requirements analysis is

critical to the success of a project. The document that contains all the requirements of the project is

termed as Software Requirement Specification

5.2.1 Input Specifications

Input specifications refer to the kind of the input that should be given to the system.

Design of Input

Input generally refers to what data is given to system so the system can give best output to user.

Input design must be complete, efficient and effective so that we can provide user with desired

output, which he requires.

When designing input, system analyst must take of the following: -

1.) What data to be Input?

2.) What medium to use?

27 Amit Katyal(81411057005)

8/3/2019 1my Report (2)

28/34

RIET Phagwara

3.) How data should be arranged or coded?

4.) The dialogue to guide the users in providing input?

5.) Data items and transactions needing validation to detect errors?

6.) Methods for performing input, validation and steps to follow when errors occur?

5.2.2 Output Specifications

Output specifications refer to the kind of the output that should be received from the system.

Design of Output

Output as you probably know generally refers to the results and information that are generated by

the system. For many end users, output is the main reason for developing the system and the basis

on which they will evaluate the usefulness of the application.

When designing output, system analyst must accomplish the following:-

1.)Determine what information to present?

2.)Whether to display, print, or speak the information and select output the medium?

3.)Arrange the presentation of information in an acceptable format.

4.)Decide how to distribute the output to intended recipients.

The arrangement of information on a display or printed documented is termed as layout.

Accomplishing the general activities listed above will require specific decision, such as weather to

use preprinted forma when preparing reports and documents, how many lines to plan on a printed

page, or whether to user graphics and color.

The output design is specified on layout forms, sheets that describe the location, characteristics and

format of the column heading and pagination. As we indicated at the beginning of the discussion

these elements are analogous to an architects blue-print that show the location of each component.

5.3 Data Flow Diagrams

As information moves through software, it is modified by a series of transformations. A DFD is a

graphical technique that depicts information flow and transform data replied as data moves from

the input to output. DFD is also known as data flow graph .A DFD may be used to represent the

system or software at any level of abstraction.

Infect DFD may be partitioned into levels that represent increasing information

flow and functional detail. Therefore DFD provides mechanism for functional modeling as well as

functional modeling.

A DFD is constructed as various degree of detail about the process of the function.

At zero level or the first level DFD, also called fundamental system model or a context

model, represent the entire software elements as a single bubble with an input and output data

indicated by incoming and outgoing arrows respectively.

Design

6.1 Database Design

A decade ago, database was unique to large corporations with mainframes. Today it is recognized

as a standard of MIS and is available for virtually every size of computer. Before the database

concept became operational, users had programs that own data independent of other users. It was a

conventional file environment, common data are available and used by several users. Instead of

each program managing its own data, data across application are shared by authorized users with

the data base software managing the data as an entity. A program now requests data through the

data base management system, which determines data sharing.

Objectives of Database

The general theme behind a database is to handle information as an integrated whole. There is none

of artificiality that is normally embedded in separate files or applications. A database is a collection

of interrelated data stored with minimum redundancy to serve many users quickly and efficiently.

The general objective is to make information access easy, quick, and inexpensive and flexibility for

the user. In data base design, several specific objectives are considered:

Controlled redundancy

Accuracy and Integrity

Data Integration

Data Integrity
