About Visual Basic.Net

Platform: .NET Framework

The .NET Framework is an environment for building, deploying, and

running Web Services and other applications. It is the infrastructure for the

overall .NET platform. The framework consists of there main parts: the

Common Language Runtime (CLR), the Class Libraries, and ASP.NET.

The Common Language Runtime and Class Libraries includes

Windows Forms, ADO.NET and ASP.NET which are combined together to

provide services and solutions that can be easily integrated within and across

a variety of systems. The .NET Framework provides a fully managed,protected and feature rich application execution environment, simplified

development and deployment and seamless integration with a wide variety

of language.

Microsoft Visual Basic.NET

Visual Basic Dot Net offers full Object-Oriented Language

features, including implementation and inheritance. It also allows developers

to create highly scalable code with explicit free threading and highly

maintainable code with the addition of modernized language constructs like

structure exception handling.

Microsoft Visual C#.Net

Microsoft C#.Net is a modern, object oriented, type safe language. It

enables programmers to quickly build a wide range of applications for the

new Microsoft.Net platform. More than anything else, C# pronounced C

Sharp is designed to bring rapid development to the C++ programmer

without sacrificing the power and control that have been a hallmark of C and

C++.

Microsoft Visual C++.Net

Visual C++ provides deep support for creating XML web services

including ATL servers and a new project type for creating powerful server-

based applications. With attribute based programming any function can be

easily exposed as an XML web service. Traditional unmanaged C++ and

new managed C++ code can be mixed freely within the same application.

Existing components can be wrapped as .NET components by using the

managed extension. This preserves investment in existing code while

integrating with the .NET Framework.

ADO.NET

ActiveX Data Objects.NET (ADO.NET), formerly known as ADO+ is

a new set of classes that expose the data access services of the .NET

Framework. ADO.NET is a natural evolution of ADO and is built around N-

Tier application development.ADO.NET has been created with XML at its

core.

The ADO.NET object model is composed of two central

components: the connected layer, which consist the classes that comprises

the .NET Data Provider and the disconnected layer, which is rooted in the

Dataset.

.NET Data Providers includes the following components: the

Connection Object, the Command Object, the Data Reader, and the Data

Adapter. The first two should be familiar to existing ADO Programmer; they

are used to open a connection to a data source and execute a command

against it. The Data Reader loosely corresponds to a forward-only, read-only

record set. It is a highly optimized, no buffering and fire host-style interface

for getting the results of a query executed against the data source. The Data

Adapter provides the dataset.

4


5/25


The Dataset is a local buffer of tables or a collection of disconnected

record sets.

Integrated Development Environment

Visual Studio.NET provides a single Integrated Development

Environment (IDE) that helps developers build solutions faster using key

productivity features accessible by any .NET language. The IDE is a

completely customizable cockpit that enables the highest performance for

developers. It provides unified access to the designer, editors, and tools of

Visual Studio from any .NET language.

About Microsoft SQL Server 2000

Microsoft SQL Server 2000 extends the performance, reliability,

quality and ease-of-use of Microsoft SQL Server version 7.0. Microsoft SQL

Server 2000 includes several new features that make it an excellent database

platform for large-scale online transactional processing (OLTP), data

warehousing and e-commerce applications. Internet Integration

3. SYSTEM STUDY AND ANALYSIS

ERP for INDUSTRIAL MANAGEMENT SYSTEM is a highly

enhanced form of the existing system because the existing system was

being done in FoxPro. The customers are provided with user-friendly

interactive system. It automates the company to easily use the details.

The company enhances the facilities with implementing latest

technologies. This application enables the company to use the

information in a better way, which increases their services and

satisfaction. Organizational process and information distribution for

Industrial Management System is implemented using .NET

architectures. Technologies enable the application with scalability and

extended performance measurements for the industrial management.

The ERP-Industrial Management System is designed to enable the

strategic, operational, and tactical processes that support sales and

purchase information. The movement of sales and purchase

information is vital to modern system and can produce competitive

advantage and analytical status of the transactions. Without an

effective and efficient ERP-Industrial Management System, all

transactions are operating sub-optimally and manually. Managing

transaction is now a major management task requiring professional

experts for implementing cost benefit transactions for a modern

system.

3.1 Existing System

FoxPro is a one of the leading database management system an enhanced

and updated version of the Fox base+ software. To get a share of the

expanding dams market for the pc segment. Fox software Inc come out with

fox based that was almost compatible with database 111 plus. Then it was

updated and the new software was called FoxPro.

FoxPro is also called the relational database management

system. FoxPro helps you to design database files as per the requirements

and as per the specified format. It also helps you enter and manage data in

database files.

FoxPro also helps you to edit view change data in the database

through simple built in commands. FoxPro is very simple to learn the use.

The commands and simple the FoxPro commands are very powerful and

flexible.

Draw Backs:

It is a case sensitive.

It required special computer knowledge.

It is difficult to maintain.

It insures lengthy processing.

Security is not available.

transactional activities like sales order, purchase order, buyer details,

sales invoice, and purchase invoice. The problem mainly concerns to

produce the sales and purchase transaction of a company. To manage

the data more accurately and promptly and to maintain a large amount

of data stored safely for further reference.

Advantages of proposed system:

File maintenance is easy

Information can be retrieved within a fraction of seconds

Overcomes the lack of accuracy.

It enhances the security mechanism.

Redundancy of data.

4. SYSTEM DESIGN

Data Flow Diagram

The data flow diagram (DFD) is one of the most important tools

used by system analysts. Data flow diagrams are made up of a number

of symbols that represents system components. Most data flow

modeling methods use four kinds of symbols. These symbols are used

to represent four kinds of system components. Processes, data stores,

data flows and external entities. Circles in DFD represent processes.

Data flow is represented by a thin line in the DFD and each data store

has a unique name and square or rectangle represents external entities.

Unlike detailed flowchart, data flow diagrams do not supply

detailed description of the modules but graphically describes a

systems data and how the data interact with the system.

To construct a data flow diagram we use,

Arrow

Circles

Open end box

Squares

An arrow identifies the dataflow in motion. It is a

pipeline through which information is flown like the rectangle in the

flowchart. A circle stands for process that converts data into

information. An open-ended box represents a data store, data at rest or

a temporary repository of data. A square defines a source or

destination of system data.

10


11/25


Five rules for constructing a data flow diagram:

1. Arrows should not cross each other

2. Squares, circles and files must bear names.

3. Decomposed data flow squares and circles can have same

names.

4. Choose meaningful names for data flow.

4.1 Database Design

Database is the heart of this application. All information

entered into the system is stored into the database in the form of Tables. A

proper database design will facilitate immediate and fast access of data into

and out of the tables. The development of the database system is not a major

breakthrough in the computer technology rather it is a logical development

in the method used by the computer to access and manipulate data shared in

various parts of computer system. The overall objective in the development

of database technology are to treat data as an organizational resource as an

integrated whole. The software package, which helps the user to integrate

with the contents of database, is known as Database Management System.

Data Integration

Data integrity

Data independency

Data integration refers to the logical interactive of deferent piece of

data scatted in the entire system in the data base information from several

files are coordinately accessed and operated upon as through it is in single

file. Logically the information is centralized physically the data may be

located on deferent devices and is widely scatted geographically connected

through data communication facility. Data independence is the insulations of

11


12/25


application programs from the changing aspect of the physical data

organization. This is essential because deferent application need the same

data in different forms. If all the data kept in all this different forms it will

result in wastage of space due to increase in redundancy

Various tables designed for this purpose are attached in Annexure

12


13/25


4.2 Input Design

Input is one of the expensive phases of the operation of computerized

system. The input data are the life blood of a system and has to be analyzed

and designed with almost care and consideration. Input system design

features can ensure the reliability of the system and generate correct reports

from the accurate data. It also determines whether the user can interact

efficiently with the system. Different types of problem occurs with the

system usually be traced back to faculty input design method. The input data

is validated, edited, organized in an acceptable form by the system before

being processed.

Wrong messages were displayed in the screen when any invalid data

was given as input in the system. In entering data operation one needs to

know the following:

Allocated space for each field

The field sequence, which must be in source document

The format in which data field were entered

The name of the item for the specified code

Input design are attached in APPENDIX

13


14/25


4.3 Output Design

Output design produces the hardcopy regarding the information

requested or displays the output in a predefined format. It is the direct source

of information to the end user. Efficient and intelligible outputs improve the

systems relationships with the users and help in decision-making. Computer

output is most important and direct source of information to the user.

Efficient and intelligible output design should improve the systems

relationship with the user and help in design making. The nature of

processing and procedure related to the system were classified and gives the

output results.

Output from the computer storage is required primarily communicate

the result of processing to the users and provide permanent copy of the

results for later consultation. While designing the output, the type of the

output, concern format, frequency responses etc., have been taken into

consideration.

The output reports play a major role in the system. Reports are printed

periodically in order to help the authorities of the company to make

decisions and to get over all information about the system.

The various reports generated by the system are attached in Annexure.

Computer output is the most important direct sources of information

to the user efficient. Intelligible output design should improve system

14


15/25


relationship with the user and help in decision making. Hard copy is

preferred since it is to be used by the management for the future references.

The output design, various output layouts are made.

The objectives of output specification are:

To interpret and communicator the results of the computer in a way in

which they can understand.

To communicate the output design specification to the user in which

unambiguous and comprehensive errors may not occur. Outputs from a computer system are required primarily to

communicate the results of processing to user.

Outputs are also used to provide a permanent copy of these results for

later consultation.

5. SYSTEM DEVELOPMENT

Development is the state in the project where the theoretical

design is turned into a working system. The most crucial stage is achieving

a successful system and confidence on the new system for the user that it

will work efficiently and effectively.

The system can be developed only after when testing is done and if it

is found to work to the specifications.

It involves careful planning, investigation of the current system and its

constraints on development of education and training of users and testing the

system. System development is an important phase in the software

engineering process. Various approaches are there for developing a system.

Individual application approach is one of the well-known approaches for

system development. This involves the development of individual computerbased application the system serve in a specific application area in an

isolated way.

The first step in which the analyst must undertake is to understand the

current system by gathering all information about it. The required datas are

collected by several methods like:

Interviews with the management.

Questionnaires

Study of the current manuals

Observation of the functioning

16


17/25


Sampling and

Research

In a system development phase, all the codes of the application are

generated. This approach has got a number of advantages. The system is

easier to develop and implement because applications are small and

relatively simple.

6 TESTING AND IMPLEMENTATION

6.1 System Testing

System testing makes a logical assumption that if all the paths of thesystem are correct, the goal will be successfully achieved. System testing is

aimed at ensuring that the system works accurately and efficiently before it

can be operated on live data. The logical design is thoroughly done and

continuously examined. Inadequate testing may lead to error may explode

into a much larger problem in course of time if not needed properly. The

proper choice of test is as important System Testing makes a logic

assumption that if all the paths of as test itself.

The main objective for testing is described as follows:

Testing is a process of executing a program with the intent of finding

an error.

A good test case is one that has a high probability of finding an as-yet

undiscovered error. A successful test is on e that uncovers as-yet undiscovered errors.

Software is the only one element of a large computer-based system.

Ultimately, software is incorporated with other system elements (e.g.,

hardware, people, information), and a series of system integration and

validation tests are conducted. These tests fall outside the scope of the

software process and are not conducted solely by software engineers.

However, steps taken during software design and testing can greatly improve

the probability of successful software integration in the larger system.

18


19/25


TESTING METHODOLOGIES

1. UNIT TESTING

Unit testing focuses verification efforts on the smallest unit of

software Design, the module. This is also known as Module Testing. The

modules are tested separately. This testing is carried out during

programming stage itself. In this testing step each module is found to be

working satisfactorily as regard to the expected output from the module.

2. INTEGRATION TESTING

Data can be lost across an interface. One module can have an adverse

effort on the other. Sub functions, when combined, may not

produce the desired major functions. Integration testing is a

systematic testing for constructing he program structure, while at

the same time conducting tests to uncover errors associated within

the interface. The objective is to take unit tested module and build a

program structure. All the modules are combined and tested as a

whole. Here correction is difficult because the vast expense of the

entire program complicate the isolation of causes. Thus in the

integration testing step, all the errors are uncovered are corrected

for the next testing steps.

3. VALIDATION TESTING

After Integration Testing, the software is completely assembled as a

package, interfacing errors have been uncovered and corrected and then test

of software is conducted i.e., Validation Test. Validation Test succeeds

when the software function in a manner that can be reasonably expected by

19


20/25


the client. Software validation is achieved through series of Black Box

Testing, which confirms with the requirements.

4. BLACKBOX TESTING

Black box testing is conducted at the software interfaces. This test

through is designed to uncover errors interfaces. This test through is

designed to uncover errors interfaces, is also used to demonstrate that

software functions are operational, input is properly accepted, output

are produced correctly and that the integrity of external information

are maintained.

Black Box Testing attempts to find errors in the following categories:

Incorrect or missing functions.

Interface errors.

Errors in Database Structure.

Performance and termination errors.

5. OUTPUT TESTING

After performing the validation testing, the next step is output testing

of the proposed system since no system could be useful if it does not

produces the required output in the specific format. The outputs generated or

displayed by the system under consideration are tested by asking the user

about the format required by them. Here, the output format is considered in

two ways, one is on the screen and another is printed format.

20


21/25


6. USER ACCEPTANCE TESTING

User acceptance testing in a system is the key factor for the success of any

system. The system under consideration is tested for user acceptance by

constantly keeping in touch with the prospective system users at time of

developing and making changes wherever required.

This is done with regard to the following points:

Input screen design

Output screen design

The above testing are done taking various kinds of test data.

Preparation of test data plays vital role in the system testing. After preparing

the test data the system under study is tested using that test data. While

testing the system by using test data errors are again uncovered and

corrected by using above testing steps.

21


22/25


6.2 System Implementation

Implementation is the process of converting a new or revised system

design into an operational one. Thus it can be considered to be the chanciest

stage in achieving a successful new system and its vital to assure the user

confidence that the proposed new system will never cause impairs and it will

be effective. If implementation is not carefully planned and controlled, it can

cause chaos.

Consultation and a demonstration were given to them about the

working of the system. The aim of the system illustration was to identify any

logical miss-working of the system when various combinations of test data

were fed. Processing accuracy and reliability checking were also made.

The first task in implementation is the implementation planning, that

is deciding on methods to be adopted. This is done in view of any last

minute changes that will be necessary in the formats. After the approval of

the system by the user and the system manager, the system was implemented

in the user department.

The three approaches of implementation are direct, parallel and

changeover. In the first approach, the existing system is rejected and the new

system is completely implemented. In parallel approach both existing system

and new system will be working simultaneously. Direct method of

implementation is followed in this project.

22


23/25


7. CONCLUSION

The Developed system is highly interactive and user friendly. The

project was tested under different conditions was found to be effective. The

project ERP- INDUSTRIAL MANAGEMENT SYSTEM was designed

and developed to save time gives lesser strains and generates quicker and

accurate results. Reports have been generated so that it meets user

requirements to the maximum possible extents. The system provides

accurate updating, data validation and integrity.

The system has been designed and run to satisfy the needs of the

entire organization. The existing system makes the job very difficult. The

new system reduces work and also results in quick retrieval of information,

which is very vital to the progress of an organization. The project has been

successfully completed and tested using the sample database information.

The system has been developed with the present working conditions. The

industrial environment is very fast with new features, styles etc are expected.

23


24/25


8 SCOPE FOR FURTHER DEVELOPMENT

This system is very flexible so that the maintenance and furtheramendments based on the changing environment and requirements can be

made easily. Any changes that may lead to the system failures are prevented

with security measures. The project will support multi user environment

that is, more than one user can access a single application simultaneously.

It can be further developed to include more operations and analysis, as

changes are required in the system to adapt to the external developments that

is, when the company carry out local sales in future. The sales module can

be included and the transactions involved in local sales can also be

maintained. Further enhancements can be made to the system at any later

point of time.
