A Project Report on

CABLE NETWORK MANAGEMENT SYSTEM

By

Nilesh Kolhe

ABSTRACT

Objective/Aim of the project:



6

This project aims at developing an application which will help a cable

network/cable operator company to easily manipulate their database for customer

information and other relevant information based on some pre decided criteria. The cable

operators will be able to search, modify and display details of each and every subscribed

customer.

Only one user profile will be available i.e. administrator. The administrator has

access to all rights/privileges offered to them. The administrator can add, update and

delete a record, as and when required.

INTRODUCTION

The Cable Network Management System software is a dual end software, i.e it has two

ends – the Front End and the Back End. The Front End is concerned with user interaction



7

while the back end is used to store the database. Connection is made between the two

ends via the “connection stream”. The Front End software is developed by using Visual

Basic 6.0 while the Back End is developed by using Oracle 9i which is a software which

supports Structured Query Language.

Features:

• Plan details:

The project will have enlisted categorized service plans from which the

administrator will be able to keep track of the plan selected by the user.

The project will also give details of the plan validity/plan duration selected by the

user.

• Bill generation:

According to the plan selected and the plan duration, the

administrator will be able to generate the bill for commercial

purposes.



8

SCOPE OF THE PROJECT

In today’s world, almost everything has become dependent on the computer. All the

major companies of all kinds develop their own softwares by which they can manipulate

their databases. These databases are of great importance as they store the

financial/commercial records of the company.

Our project entitled “Cable Network Management System” is an example of such a

database manipulation application.

Our project can be put to commercial use in the industry. All cable TV operator

companies have a huge database of customers that they need to manage. They need to

keep track of the customer’s personal details along with their account details such as date

of subscription, type of service plan selected, plan duration and more importantly the bill

generated after each month according to the selected plan and its duration.

Our project satisfies all these requirements. Since it has only one profile i.e

administrator, only the privileged individuals will be able to access the company data and

thus security of the product is preserved. Thus, the application has a great potential in the

upcoming Information Technology industry.

SOFTWARE SPECIFICATIONS

Operating System: - Windows 98/XP/Vista/7

Front End: - VISUAL BASIC 6.0 (VB 6.0)

Back End: - Oracle 9i



10

• FRONT END

For the Front end we have used the VB i.e. Visual Basic.

The “Visual” part refers to the method used create the graphical user interface[GUI]. Rather than writing numerous lines of interface elements, you simply add pre-

built objects into place on screen.

The “Basic” part refers to the BASIC [Beginners All Purpose Symbolic

Instruction Code] language, a language used by more programmers than any other

language in the history of computing. VB has evolved from the original BASIC language

and now contains several statements, functions and keywords, many of which relate

directly to the window GUI.

VB is very popular language because it allows rapid development of window

based applications. VB is commonly used for creating front end or interface of

application. It is easy to learn and easy to understand programming language. It supports

many wizards, which makes complex task easier.

It stands in non-structural language. It has different objects displayed in front end

for input/output from user. Each object and front end things have the code written is

executing in its background. VB has three editions:-

• Learning- Intrinsic controls, plus grid and data bound controls

• Professional- All controls from learning edition + Active X controls

• Enterprise- All the features of professional edition plus back office tools such as

SQL Server, Microsoft Transaction Server, Internet Information Server, Visual

SourceSafe, SNA Server etc.

When the VB window is opened it shows startup screen used to select the type of

project design in VB. VB window is called as an IDE [Integrated Developed

Environment]. It refers as an IDE because it integrates many functions such as editing,compiling, linking and debugging within single environment.

The VB IDE consists of:-

1] Menu Bar

2] Toolbar

3] Toolbox



11

4] Property window

5] Form layout window

6] Project explorer window

7] Object browser

8] Form designer

9] Code editor window

Some Features of VB:

• Menu Interface:-

Adding menus to it can enhance VB application. It offers a convenient and

consistent way to group commands and an easy way for access them. Using the menu

editor, we can add new commands to executing menus, create new menus and menu bars,

change and edit existing menus and menu bars.

• Graphics:-

VB provides a variety of ways to create and use graphics in an application, which

adds styles, interest and visual structure to the interface of an application. Graphic objects

such as lines, circles and bitmaps can be displayed in VB in a quicker and easier way.

• Multiple Document Interface:-

A Multiple Document Interface [MDI] is used for opening many windows at the

same time. All the document windows are contained in a parent window, which provides

a workspace in the application.



12

• BACK END

For the back end purpose means the connection of various tables and databases

we are using the Structured Query Language (SQL). The term database means thecollection of fields and records. The term database is collection of all tables that

composes the complete system. SQL offers a variety of features for different databaseneeds.

SQL is the language using which we can perform the operation like create,

retrieve, add, modify, delete and control access to ORACLE database. SQL is a non-procedural language.

SQL*PLUS is not a language. It is a powerful support product. It is an

environment which enables us to manipulate SQL commands, PL/SQL blocks and many

additional tasks.SQL commands are standard SQL commands used for working with data in

database. SQL is made of three sub-language, they are Data Definition Language (DDL),Data Manipulation Language (DML) and Data Control Language (DCL).

The Data Definition Language consists of a set of commands used to create

objects such as tables, views and indexes. The Data Manipulation Language is used for

query, insertion, updating and deletion of data stored in database. The Data ControlLanguage is used for controlling access to data.

SQL can be used to develop three general type of application.

1. Application used to run small business:-SQL is excellent platform for developing an application that runs a small

business, its wizards allows developers to quickly and easily build a foundation of the

application.

2. Departmental application:-

SQL is perfect for developing application for departments within large

corporation. It is relatively easy to upgrade the user within a department to appropriatehardware.

3. Corporation wide application:-

SQL can also used to produce application that distribute throughout the

organization.

Features of SQL:

• Working on other applications

• Working with sample applications

• Working in the database window



13

• Using & customizing toolbars, menu bars & shortcut menus

• Working with data

• Working with filters

• Printing and previewing

• Designing a database

• Creating and customizing a query

• Creating and customizing forms and reports

• Securing and administering a database

Thus we can use SQL efficiently as backend tool.

FUTURE ENHANCEMENTS

1) If the administrator changes, then provisions will be made to add another administrator

with same privelage level as that of his predecessor. The new administrator will have a

new login ID and a new password.

2)If the cable operator company introduces a new plan, then provisions will be made for

users to be able to select the new plan.

3)If data rate of the existing plan changes, then provisions will be made for the

administrator to change the data rate of the changed plan.



39

CONCLUSION

In this way, after a lot of research, hardwork and dedication by all three of us, we have

successfully completed and implemented the mini-project entitled “Cable Network

Management System” on Relational Database Management System (RDBMS) and Front

End development.
