Technology Overview of my Project
Microsoft Access 2007
Microsoft Access is a relational database management system (RDBMS) that is packaged
with the Microsoft suite of office products to run under the Microsoft Windows operating
system. Microsoft Access is a Visual Basic (VB) based application that allows Structured Query
Language (SQL) statements to be included in associated macros and VB scripts. Microsoft
Access includes a Jet database engine, combined with a graphical interface, to provide ease of
use in building front-end database applications. Microsoft Access is a structured environment,
used by novice programmers, with little or no experience, to handle relatively small database
functions. It is also a useful tool, for advanced developers, to provide rapid application
development.
Though MS Access has been successfully front-ended against databases, including itself,
Microsoft Access does not scale well for large databases or multiple-access, network
environments. The underlying Jet Database is a file-sharing database that performs all processing
at the client level. As such, Microsoft Access is not designed for high volume multi-user
environments that allow multiple clients to read, write and perform other operations on shared
files at the same time.

10

Visual Basic 6.0

Visual Basic (VB) is the third-generation event-driven programming language and integrated development environment (IDE)
from Microsoft for its COM programming model. Because of its graphical development features and BASIC heritage, VB is
considered to be relatively easy to learn and use.[1]
Visual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface
(GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation
of ActiveX controls and objects. Scripting languages such as VBA and VBScript are syntactically similar to Visual Basic, but
perform differently.
A programmer can put together an application using the components provided with Visual Basic itself. Programs written in
Visual Basic can also use the Windows API, but doing so requires external function declarations.

Like the BASIC programming language, Visual Basic was designed to be easily learned and used by beginner
programmers. The language not only allows programmers to create simple GUI applications, but can also develop
complex applications. Programming in VB is a combination of visually arranging components or controls on a form,
specifying attributes and actions of those components, and writing additional lines of code for more functionality.
Since default attributes and actions are defined for the components, a simple program can be created without the
programmer having to write many lines of code. Performance problems were experienced by earlier versions, but
with faster computers and native code compilation this has become less of an issue.
Although programs can be compiled into native code executables from version 5 onwards, they still require the
presence of runtime libraries of approximately 1 MB in size. This runtime is included by default in Windows
2000 and later, but for earlier versions of Windows like 95/98/NT it must be distributed together with the
executable.
Forms are created using drag-and-drop techniques. A tool is used to place controls (e.g., text boxes, buttons, etc.) on
the form (window). Controls have attributes and event handlers associated with them. Default values are provided
when the control is created, but may be changed by the programmer. Many attribute values can be modified during
run time based on user actions or changes in the environment, providing a dynamic application. For example, code
can be inserted into the form resize event handler to reposition a control so that it remains centered on the form,

11

expands to fill up the form, etc. By inserting code into the event handler for a keypress in a text box, the program
can automatically translate the case of the text being entered, or even prevent certain characters from being inserted.
Visual Basic can create executables (EXE files), ActiveX controls, or DLL files, but is primarily used to develop
Windows applications and to interface database systems. Dialog boxes with less functionality can be used to provide
pop-up capabilities. Controls provide the basic functionality of the application, while programmers can insert
additional logic within the appropriate event handlers. For example, a drop-down combination box will
automatically display its list and allow the user to select any element. An event handler is called when an item is
selected, which can then execute additional code created by the programmer to perform some action based on which
element was selected, such as populating a related list.
Alternatively, a Visual Basic component can have no user interface, and instead provide ActiveX objects to other
programs via Component Object Model (COM). This allows for server-side processing or an add-in module.
The language is garbage collected using reference counting, has a large library of utility objects, and has basic object
oriented support. Since the more common components are included in the default project template, the programmer
seldom needs to specify additional libraries. Unlike many other programming languages, Visual Basic is generally
not case sensitive, although it will transform keywords into a standard case configuration and force the case of
variable names to conform to the case of the entry within the symbol table. String comparisons are case sensitive by
default, but can be made case insensitive if so desired.
The Visual Basic compiler is shared with other Visual Studio languages (C, C++), but restrictions in the IDE do not
allow the creation of some targets (Windows model DLLs) and threading models.

Characteristics
Visual Basic has the following traits which differ from C-derived languages:


Multiple assignment available in C language is not possible. A = B = C does not imply that the values of A,

B and C are equal. The Boolean result of "Is B = C?" is stored in A. The result stored in A would therefore be
either false or true.


Boolean constant True has numeric value −1. This is because the Boolean data type is stored as a 16-bit

signed integer. In this construct −1 evaluates to 16 binary 1s (the Boolean value True), and 0 as 16 0s (the
Boolean value False). This is apparent when performing a Not operation on a 16 bit signed integer value 0
which will return the integer value −1, in other words True = Not False. This inherent functionality becomes
especially useful when performing logical operations on the individual bits of an integer such
as And, Or, Xor and Not.[4] This definition of True is also consistent with BASIC since the early 1970s
Microsoft BASIC implementation and is also related to the characteristics of CPU instructions at the time.

12



Logical and bitwise operators are unified. This is unlike some C-derived languages (such as Perl), which

have separate logical and bitwise operators. This again is a traditional feature of BASIC.


Variable array base. Arrays are declared by specifying the upper and lower bounds in a way similar

to Pascal and Fortran. It is also possible to use the Option Base statement to set the default lower bound. Use of
the Option Base statement can lead to confusion when reading Visual Basic code and is best avoided by always
explicitly specifying the lower bound of the array. This lower bound is not limited to 0 or 1, because it can also
be set by declaration. In this way, both the lower and upper bounds are programmable. In more subscriptlimited languages, the lower bound of the array is not variable. This uncommon trait does exist in Visual
Basic .NET but not in VBScript.

OPTION BASE was introduced by ANSI, with the standard for ANSI Minimal BASIC in the late
1970s.


Relatively strong integration with the Windows operating system and the Component Object

Model. The native types for strings and arrays are the dedicated COM types, BSTR and SAFEARRAY.


Banker's rounding as the default behavior when converting real numbers to integers with

the Round function.[5] ?


Round(2.5, 0) gives 2, ? Round(3.5, 0) gives 4.

Integers are automatically promoted to reals in expressions involving the normal division operator

(/) so that division of one integer by another produces the intuitively correct result. There is a specific
integer divide operator () which does truncate.


By default, if a variable has not been declared or if no type declaration character is specified, the

variable is of type Variant. However this can be changed with Data type statements such
asDefInt, DefBool, DefVar, DefObj, DefStr. There are 12 Data type statements in total offered by Visual
Basic 6.0. The default type may be overridden for a specific declaration by using a special suffix character
on the variable name (# for Double, ! for Single, & for Long, % for Integer, $ for String, and @ for
Currency) or using the key phrase As (type). VB can also be set in a mode that only explicitly declared
variables can be used with the command Option Explicit.

SOFTWARE REQUIREMENTS SPECIFICATION
1. Introduction
1.1 Purpose :
Crime File System is a system used to report crimes. This project is mainly useful for police
Departments. This system will help to manage all the activities in a police Department using
computers. Currently all the works are done manually, by computerizing all the activities inside a
police Department can be managed easily and effectively.
The police Departments in the country are, today, virtually unconnected islands. Thanks to
telephones and wireless, and especially thanks to mobile telephones, there is voice connectivity
between the police Department and senior police officers, but that is about all. There is no
system of data storage, data sharing and accessing data. There is no system under which one
police Department can talk to another directly. There is no record of crimes or criminals that can
be accessed by a Department House Officer, except the manual records relating to that police
Department. The goals of the system are to facilitate collection, storage, retrieval, analysis,

14

transfer and sharing of data and information at the police Department and between the police
Department and the State Headquarters and the Central Police Organizations.

1.2

Scope:

1. The system ‘CRIME FILE’ will be a Reporting application that will be used for
automating the manual process of register different case in police Department .This
system will manage the details of all the crime who register themselves in police
Department. The system provides an interface to store the crime details of criminals or
prisoners and allows the user to search and view records. The system should have a
login. System should support for Data Entry module for Nominal Roll, Case register for
each prisoner entering in the prison

The system will greatly simplify the overall procedure of crime files.

DATA FLOW DIAGRAM

The data flow diagram enables the software engineer to develop models of the information
domain and functional domain at the same time. As the DFD is defined into greater level of
details, the analyst performs as implicit functional decomposition of the system, thereby
accomplishing the fourth operational analysis principle for functions. At the same time, the DFD
refinement results in a corresponding refinement of data as it moves through the processes that
embody the application

MANAGE THE LIST OF MOST WANTED CRIMINALS

85

This is an additional feature added to this Software, which helps us to make a quick
search about the most wanted criminals. This helps to always keep track of and identify a person
quickly, who is a most wanted criminal.

TEST CASES
Test cases used in this project are:
Test case 1:

Purpose: The main purpose of this test case to inform the administrator if he did not write the
correct username or password.
Pre condition and inputs: The precondition for this test case is if the administrator write the
correct username and password, then only user will be able to access the application.
Results: if username and password is not correct, then an error mess will be displayed for
incorrect password/ username.

Test case 2:

Purpose: The main purpose of this test case to inform the administrator if any exception occurs
while updating information on the application. The format should be correct while entering the
details for the criminal or prisoner name or fir information.
Precondition and inputs: The precondition of this test case is there are validations given in the
form which indicates the correct format of the data .The user has to fill the all required field ..

86

Results: lf data format entered is not correct or any field is blank, then no account will be
generated.

FUTURE ENHANCEMENT

•

We can update this system as online application

•

The main advantage of online application is that, a person can report the

crime any time from anywhere.
•

Users can view the progress of their complaint online.

•

By the future technology user can view the case details and progress of

the complaints on their mobile phones
•

Face recognition technology can apply. User or witness of the crime can

give the physical information of the thief.

87

CONCLUSION

CRIME FILE MANAGEMENT SYSTEM initiates the objective of providing
the user with customized and powerful complaint registration and process management
system side software.

The software is built with all options such as complaint

registration, prisoner’s registration, and postmortem report generation etc…All the
requirements specified during the analysis and design phase are fully met, thus resulting
in the formation of good software. The interface provided is very user friendly and
flexible for all times.
