SYNOPSISThe Bank Loan Management System is a process which
should be done with care. Money plays a big part in such concerns.
It is a very tough process. Lot of work to be done in reservation
as well as cancellations. This process needs very accurate
calculations. The employees also need to keep the records of all
customers which include the address, gender, account number and the
transaction of money. A lot of paper work should be done. The
package is designed using Microsoft Visual Basic .net which is very
user friendly to work with. Its event driven programming helps us
to develop SQL Server 2005 object which has better connectivity to
database.The Existing system maintained manually where every
information is stored or entered as records and files. Maintaining
of records manually leads to clerical errors. Searching of records
is a tedious job while the records are maintained manually. The
administration has to maintain several files to store all the
transactions. There is no security is storing sensitive information
like the financial transaction of the administration. Due to manual
maintenance, man power in maintaining all the departments is more.
Due to manual work clerical errors occurs frequently, this creates
a huge traffic in administrating the organization.The Project
Includes Following Modules, New Customer Details Deposit Details
Master Details Account Details Loan Details Transaction Details
The Reports are,

ABOUT THE SOFTWAREVB.NETThe system is developed using Visual
Basic. NET, which is a very popular Microsoft Product developed by
Microsoft Corporation. This is one of the improved languages from
basic language. Visual basic. NET includes a variety of open active
controls for user interfaces to design application formOVER VIEW OF
.NET FRAMEWORKThe .NET framework is a new computing platform that
simplifies application development in the highly distributed
environment of the internet.The .NET framework is designed to
fulfill the following objectives. To provide a consistent object
oriented programming environment whether object code is stored and
executed locally, but internet-distributed, or executed remotely.To
provide a code execution environment that minimizes software
deployment and versioning conflict.To provide a code execution
environment that guarantees safe execution of code, including code
created by an unknown or semi trusted third party.To provide a
code-execution environment that eliminates the performance problems
of scripted or interpreted environments.To make the developer
experience consist ant across widely varying types of applications,
such as windows-based applications and web-based applications.To
build all communication on industry standards to ensure that code
based on the .NET framework can integrate with any other code.The
.NET framework has two main componentsCommon Language Runtime
(CLR).NET framework class library.Common Language Runtime (CLR).The
common language runtime is the foundation of the .NET framework
.you can think of the runtime as an agent that manages code at
execution time, providing core services such as memory management
and thread management while also enforcing strict type safety and
other forms of code accuracy that ensure security and robustness.In
fact, the concept of code management is a fundamental principal of
the runtime .Code that targets the runtime isknown as managed code,
while code that dose not target the runtime is known as unmanaged
code.The .NET framework can be hosted by unmanaged components that
load the common language runtime into their processes and initiate
the execution of managed code, thereby creating a software
environment that can explicit both managed and unmanaged features.
The .NET framework not only provides several runtime hosts, but
also supports the development of third-party runtime hosts.Internet
explore is an example of an unmanaged application that runtime (in
the form of a mime type extension).Using internet explorer to host
the runtime enables you to embed managed components or windows from
controls in the HTML documentThe Components Of CLR Are:CTS
=>Common Type System.CLS =>Common Language SpecificationCIL
=>Common Intermediate LanguageJIT =>Just In Time Compiler VES
=>Virtual Execution SystemCTS Common Type System This is the
range of types that the .NET runtime understands, and therefore
that .NET application can use. The common type system supports both
object oriented programming like java as well as procedural
languages like c .It deals with two kinds of entities such objects
and values.
CLS-Common Language Specification This is a subset of the CTS
that all .NET languages are expected to support. The idea is the
any program that uses CLS-compliant types can interoperate with any
.NET program written in any language. If a component written in one
language (say c#) is to be used from another language (say VB.NET)
then the component writer must adhere to type and structures
defined by CLS. CIL-Common Intermediate Language All compilers
complying with CLR must generate an intermediate language
representation called common intermediate language (CIL). The CIL
uses this intermediate language to either generate native code or
use just in compiler (JIT) complication to execute the intermediate
code on the fly.JIT-Just In Time Compiler The JIT or just in time
compiler is the part of the runtime execution environment, which is
used to convert the intermediate language contained in the
execution file, called assemblies , into native executable code.
The security policy settings are referred at this to decide if code
being compiled needs to be type safe.VES-Virtual Execution System
Virtual execution system (VES) is more or less equivalent to the
JVM (Java Virtual Machine).VES loads, links and runs the programs
written for common language infrastructure contained in portable
executable (PE) files.VES fulfill its loader function by using
information contained in the metadata and uses late binding (or
linking) to integrate modules compiled separately, which may even
be written in different languagesNET Framework Class Library The
.NET framework library is a collection of reused types that tightly
with the common language runtime (CLR). The class library is object
oriented, providing type from which your own managed code can
derive functionality. Managed codes are intermediate language codes
along with metadata contained in portable executable (PE) files.
This not only makes the .NET framework type easy to use, but also
reduces the associated with learning new features of the .NET
framework. In addition, third party components can integrate
seamlessly with classes in the .NET framework .for example ,the
.NET framework collection classes implement a set of interfaces
that you can use to develop you r own collection classes .your
collection classes will blend seamlessly with the classes in the
.NET framework.One can use the .NET framework to develop the
following types of application and services.Console application
Scripted and hosted application Windows GUI application (windows
forms)VB.NET application XML web servicesVisual Basic .Net Visual
basic .NET preserves VBs general approach to programming with a SDK
development environment and click through forms to get at the
underlying code. The Visual Basic IDE is made up of a number of
components given below
Forms ToolboxTabs Properties windowsSolution explorerOutput
windowsTask list window
Forms A form is one of the most basic objects in which the
application code and acts as a container for the controls placed on
it thus providing a visual interface. VB.NET initially includes a
default form. Toolbox The toolbox is an important window, which
contains a set of controls. It contains the controls to create our
forms non-graphical components such as database connections and
code fragments that can be dragged directly from the toolbox into
the code window.Tabs Different tabs are organized in the toolbox.
Some of the tabs areData: Contains components that access to data
and data sources.Components: Contains various components such as
Reporting, message queuing etc.Clipboard ring: Contains a list of
the last few items that is copied to the system clipboard.General:
Empty by default, this is a place for us to store general controls,
components, and code fragments.Win forms: Containing windows form
controls is automatically available when windows project is
included in the project.Web forms: Contains server side web form
controls that are used to create web pages.HTML tab: Contains
controls that correspond to the standard HTML tags.Properties
WindowThe properties window appears beneath the solution explorer
on the right-hand of the VS.NET main window. It displays the
properties for the currently selected object in the main window.
Pressing key F4 also displays the properties window for the
selected object.Solution ExplorerSolution explorer window is
similar to the project explorer window in the Bathe solution
explorer is a bit more advanced, since it allows us to construct
solutions out of several different projects including those written
in different languages.Class View The class view window is somewhat
similar to the solution explorer, in the it provides a view into
our solution and project. A view of classes, methods and properties
rather than a view of files are provided by the class view in the
world of object-oriented world of .NET.Server ExplorerServer
explorer is an exciting new feature of VS.NET as it allows us to
explore and access server components in nice graphical
environments. The server explorer lists the data connections and
the servers that are available to the user. It can be used to
examine and manipulate servers and the databases they contain in
the server explorer. Output WindowThe output window is similar to
the immediate window available in the previous version of visual
basic. The immediate window is used to view debug output from the
application, and to interact with the environment by entering bits
of code or even calling procedures within the users code.Task List
Window Task list window is a feature that is used to provide a
quick list of all the current build and syntax errors in our
application. The main advantage of using the task list is that by
double-clicking on an error listed in the window will take us right
to the troublesome point in our code.
SQL SERVER 2000 Microsoft SQL Server 2000 is a full-featured
relational database management system (RDBMS) that offers a variety
of administrative tools to ease the burdens of database
development, maintenance and administration.Enterprise Manager is
the main administrative console for SQL Server installations. It
provides you with a graphical "birds-eye" view of all of the SQL
Server installations on our network.Query Analyzer offers a quick
and dirty method for performing queries against any of our SQL
Server databases. It is a great way to quickly pull information out
of a database in response to a user request, test queries before
implementing them in other applications, create/modify stored
procedures and execute administrative tasks. SQL Profiler provides
a window into the inner workings of your database. SQL Profiler
allows you to capture and replay system "traces" that log various
activities. It is a great tool for optimizing databases with
performance issues or troubleshooting particular problems.Service
Manager is used to control the MS SQL Server (the main SQL Server
process), MSDTC (Microsoft Distributed Transaction Coordinator) and
SQL Server Agent processes. An icon for this service normally
resides in the system tray of machines running SQL Server.FEATURES
OF SQL SERVER 2000Internet IntegrationThe SQL Server 2000 database
engine includes integrated XML support. It also has the
scalability, availability, and security features required to
operate as the data storage component of the largest Web sites. The
SQL Server 2000 programming model is integrated with the Windows
DNA architecture for developing Web applications.Scalability and
AvailabilityThe same database engine can be used across platforms
ranging from laptop computers running Microsoft Windows 98 through
large, multiprocessor servers running Microsoft Windows 2000 Data
Center Edition. SQL Server 2000 Enterprise Edition supports
features such as federated servers, indexed views, and large memory
support that allow it to scale to the performance levels required
by the largest Web sites.Enterprise-Level Database FeaturesThe SQL
Server 2000 relational database engine supports the features
required to support demanding data processing environments. The
database engine protects data integrity while minimizing the
overhead of managing thousands of users concurrently modifying the
database. SQL Server 2000 includes a set of administrative and
development tools that improve upon the process of installing,
deploying, managing, and using SQL Server across several sites.
Data warehousingSQL Server 2000 includes tools for extracting and
analyzing summary data for online analytical processing. SQL Server
also includes tools for visually designing databases and to analyze
the data.
CHAPTER VSYSTEM DESIGN5.1 DATABASE ANALYSISDatabase design is an
important place in designing a system. During this phase care
should be taken to avoid redundancy of information storing into a
database, since it leads to wastage of memory space.Normalization
Techniques:Normalization is a process of simplifying the
relationship between data elements in a record. Through
normalization a collection of data in a records structure is
replaced by successive record structures that are simpler and more
predictable and therefore more manageable.First Normal FormA
relation is said to be in first normal form if the values in the
relation are atomic for every attribute in the relation .By this we
mean simply that no attribute value can be a set of values or as it
sometimes expressed, a repeating group.Second Normal FormA relation
is said to be in second normal form if it is in first normal form
and it should satisfy any one of the following rules.Primary key is
a not a composite primary key.No non-key attribute is fully
functionally dependent on full set of primary keyThird Normal FormA
relation is said to be in third normal form if it is in second
normal form and if their exits no transitive dependenciesTransitive
DependencyIf two non-key attributes depends on each other as well
as on the primary key then they are said to be transitively
dependent. the above normalization principles where applied to
decompose the data in multiple tables there by making the data to
be maintained in a consistent state.

Chapter VISYSTEM TESTINGSystem testing is critical aspect of
software quality assurance and represents the ultimate Review of
specification, design and coding. Testing is a process of executing
a program with the intent of finding an error. A good testing case
is that has the probability of finding as yet undiscovered error.
The purpose of the system testing is to identify and correct bugs
in the developed system. Nothing is complete without testing.
Testing is vital to the success of the system.
6.1 SYSTEM TESTINGAfter each program passes its own test, it is
linkage to the other programs is scrutinized with a program
integration test. This ensures that the program work together as
intended. Before the implementation phase the designed system
should be tested with raw data to ensure that all modules of the
system work correctly and satisfactorily. If some bug is found they
can be removed before the implementation phase. The testing has the
four kind of testing that is as follows.
WHITE BOX TESTINGWhite box testing, sometimes called glass-box
testing is a test case design method that uses the control
structure of the procedural design to derive test cases. Using
white box testing methods, the software engineer can derive test
cases.1. Guarantee that all independent paths within a module have
exercised at least once.2. Exercise all logical decisions on their
true and false sides.3. Execute all loops at their boundaries and
within their operational bounds.4. Exercise internal data
structures to ensure their validity.
BLACK BOX TESTINGBlack box testing, also called behavioral
testing, focuses on the functional requirements of the software.
That is, black box testing enables the software engineer to derive
sets of input conditions that will fully exercise all functional
requirements for a program. Black box testing is not an alternative
to white box techniques. Rather it is a complementary approach that
is likely to uncover a different class of errors than white box
methods. Black box testing attempts to find errors in the following
categories.
UNIT TESTING Unit testing is the basic level of testing where
individual components are tested to ensure that they operate
correctly. In a properly designed system, each component should
have a precise specification, and test cases must be defined to
check that the component meets its specification. Unit testing
considers each component to be a stand-alone entity, which does not
require other system components to be present during the testing
process. The modules purchase, sales are individually unit tested
using the above approach.
ACCEPTANCE TESTING Acceptance testing involves planning an
execution of a functional test, performance test and stress test to
verify that the implemented system satisfies the requirement. The
acceptance testing is the final stage of the user the various
possibilities of the data are entered and the results are tested.
VALIDATION TESTINGSoftware validation is achieved through a series
of test that demonstrates the conformity and requirements. Thus the
proposed system under consideration has to be tested by validation
and found to be working satisfactorily. For example in customer
enters phone number field should contain number otherwise it
produces an error message Similarly in all the forms the fields are
validated
6.2 IMPLEMENTATION PLANSystem implementation is loss creative
than design but it is a crucial phase in the system life cycle. It
is primarily concerned with ordering of the items. Implementation
is the process of concerning a new system design into an
operational one. Implementation is the stage in the project where
the theoretical design is turned into a working system. The most
crucial stage is achieving a new successful system and in giving
confidence is in getting the approval for the system manager.
The data entry, the various menus and most important reports
that the system is capable of producing are shown to the staff.
This is done in view of any last minute changes that will be
necessary in the formats.When everyone is satisfied, the new system
is finally handled over to the data entry operators. The more
complex the system is being implemented, the more involved will be
the systems analysis and design effect required for the
implementation.
Chapter VIICONCLUSIONThe project is a complete automation of the
existing system. It is being developed with the facilities
available in Visual Basic .net a user friendly GUI which enables
the user to view the students details an d SQL Server.The system
ensures easy, secured and time saving .The system has been tested
with al possible samples of data and it has undergone all the tests
successfully .Te system also provides flexibility for incorporating
features, which may be necessary in the future. The Bank Loan
Management System is a tool that used to integrate various peers
that are connected the customer to depositer and bank. Thus the
system can be further extended to adopt into various fields that
involve in bank process such as new account opening, deposit the
amount, and loan payment etc., The system is having function which
will be most useful in sensitive and serious applications such as
computerized bank system and online deposit the amount. Thus the
system will enhance the functionality of those systems in a very
broad way and can even be the cause of the system newer
applications to beign.
