System Analysis 4. System Design 5. Implementation 6. Post Implementation 7. Whatever be the process involved in the system were done through register files. There were lots of complexities involved in the system. When any customer takes new connections then separate files were maintained. Updating of data was very tedious job. The manual work processes was time consuming and hence slow.
Following are the main drawbacks of the existing system: The existing system is totally manual thus there are chances of error in processing. The basic and major drawbacks in the existing system are the speed of retrieval of data from files, which leads to delay. Maintenance of voluminous data is very cumbersome and laborious job. The manual jobs such as calculation are more error prone. There are plenty of chances of duplicity of data and information.
Updating is very tedious job. There is no central database from where one can get different statistical data at one place. Since the existing system was totally manual which has lots of complexities, shortcomings in itself and all the data was being stored in registers, files etc thus to overcome the limitation of the existing system, the new computerized system was needed, so that information can be provided to the user more quickly, easily and more accurately.
Information is a vital ingredient for the operation and management of any organization. Thus any system should have the ability to provide error free filtered information after processing the required data. This system has been taken up with a view for developing a more sophisticated system that can be easily handled by any kind of users.
The proposed system aims at efficient and timely information for decision-making, integrate with other functions, and reduce redundant work. Consistent user interface with high economic features built into it. System design in modular and structured way so as to make the integration with other subsystems easier. User-friendly error messages are provided wherever necessary. Addition, deletion, modification of records as when needed. Providing connections to new customers. Bill generation for customers.
To reduce the delay in processing time. To reduce the delay in bill generation. To provide the user-friendliness in all possible ways. To provide greater flexibility. Make maintenance changes easy. To store data in a centralized location to reduce redundancy and increase consistency. PURPOSE : The purpose of the project is to develop a system which is user friendly, easy to use , maintain and satisfies all the requirements of the user. This tool uses several canvases on the same form.
Valid customer no. Individual Bills for each call types Monthly Rental 5. The functionalities of the system is designed and studied in this phase. The first step is designing of program specification. This determines the various data inputs to the system, data flow and the format in which output is to be obtained. Design phase is a transmission phase because it is a transition from user oriented document to computer data.
The activity in the design phase is the allocation of functions to manual operations, equipment and computer programs. Flow charts prepared in the study time received and decomposed until all functions in the system perform evidently. Design is a multistep process that focuses on data structures, software architecture, procedural details algorithms etc and links between the modules.
The design process goes through logical and physical stages. In logical design reviews are made linking existing system and specification gathered. Modularization of task is made in the mode. The success of any integrated system depends on the planning of each and every fundamental module. Usually a project is revised in step by step sequence. Inter phase management of such module is also important. Software design methodology changes continually as new methods, better analysis and broader understanding evolve.
Various techniques for software design do exit with the availability of criteria for design quality. Software design leads three technical activities-design, code and test.
The techniques for software design do exit with the availability of criteria for design quality. Software design leads three technical activities-design, code and test that are required to build and verify software. Each activity transforms information, which validates the software. The design system converts theoretical solution introduced by the feasibility study into a logical reality. The goal of design input data is to make data entry as easy, logical and free.
The most common source of data processing errors is inactive input data. Effective design of the input data minimizes the error made by data entry operators. Catching errors on input is far less costly than correcting after data storage is complete. User-friendly input design enables quick error detecting and correction. Verification and validation is the most important in input design.
Since the system is used interactively, it has two types of inputs. Interactive input-which is the point contact of the user with the system and the input to the internal system i. For full efficiency of the system, it is necessary that the input must be accurate. Since the user of the system may not be a technical person and may not know input concepts so it is required that he warn, prevent and correct invalid data entry.
There are many ways that can be designed to handle such a situation. We can prevent the user entering invalid data into the databases by warning, neglecting or messaging appropriately. The user is then allowed to input correct data. Some help provisions may aid the user to point out the error. In this system inputs are collected from terminals through keyboard.
The objective of the output design is to convey the information of all past activities, current status and to emphasize important events.
The output generally refers to the results and information that is generated from the system. The output design of the system is accomplished keeping in mind the following activities: Determine what information is to display. Decide whether to display or print the information retrieved, processed, generated from the system. Arrange the presentation of information in an acceptable format. Decide how to distribute the output to the intended recipients.
In the output design phase one or more output media can be selected. Out of which the most common ones are CRT displays and print out. Here only CRT display has been attempted. A rapid enquiry is obtained from CRT displays. From design is made interesting and attractive. Easy understanding and effectiveness is made possible. Mouse as pointing device. Software Environment The application front end will be designed using Visual Basic 6. The database has been designed on Microsoft Access Office Package.
Building a windows program in Visual Basic requires dragging and dropping graphic objects on to the screen from a toolbox. Visual Basic 6. The programming language forms the background of all that takes place in a running Visual Basic program.
The language is a secondary consideration to the user interface. A windows program offers a high degree of user interaction using the graphical elements that forms the objects on the window the user sees. If the user interface is not correct, user will not like the program. Visual Basic lets one add menus, text boxes, command buttons, option buttons for making exclusive choice , check boxes, list boxes, scroll bars and file and directory boxes to black windows.
One can use Visual Basic to communicate with other applications, running under windows. Visual Basic offers: More Internet features, better support for data base development, more language feature to make programming job easier. Active X technology allows using functionality provided by other applications such as Microsoft Word, Microsoft Excel and other applications and objects could be created using the Professional Enterprise editions of Visual Basic. Internet capabilities make it easy to provide access to documents and applications across the Internet or Intranet server applications.
The finished applications are a true. The Tool Box is a collection of tool that acts as a repository of controls we can place on forms. Form: Visual Basic uses a window; controls are the widgets one place of a form. In a form we will customize by adding controls such as command buttons, list boxes to it. At the top of the black form is the little bar with its caption.
Common Form properties: There are several common properties to customize a form, these are: Caption: Caption is used as a title that the Microsoft Window for the application icon when the user minimizes the application.
Name: This property is used to give the name that one want to use to refer to the form. Enabled: If user sets Enabled to false, the form cannot respond to any events such as the user checking on the form. Icon: The icon property determines the icon users application will display when it is minimized on tool bar or turned into a stand-alone application on windows desktop.
Visible: If the value of the property is set to false, it will no longer be visible. Text Boxes: It is used to display text or to accept user input. Most of the code is written to process the information users enter into them.
Several properties of text boxes are as follows: Text: The text property in text box is the analog of the caption property for a command button or a form; it controls text the users see. It determines whether text on the control such as label or command button, is left justified, centered, or right justified on the control. The Alignment property take one of the three values: 0-Left justify, 1-Right justify, 2-Center. Multiline: This property determines whether a text box can accept more than one line of text when the user runs the application, and it is usually combine with resulting the value of the scrollbar property.
If true the property specifies the text box can hold more than a line of text. Max Length: This property specifies the maximum number of characters that the text box will accept. A value of 0 indicates that the user can enter a value of any length.
Locked: This property determines whether the user can enter a value or change the default value of the text box. If true, the user cannot change the text box value until the program, at run time assigns a false to this property.
Password char: The Password property lets us limit what the text box displays. Labels: Use Labels to display information programmer does not want the user to be able to change. Most common use for Labels is to identify a text box or other control by describing its contents. Another common use is to display help information. Message Boxes: Message boxes display information in the dialog box superimposed on the form.
They want for the user to choose a button before return to the application. User cannot switch to another form in programmers applications as long as Visual Basic is displaying a message box.
MsgBox The message goes in codes, 4 Frames: Programmer usually frames passively to group images or controls. Option Buttons: They all work together. When the user chooses one button, all other buttons in the group are turned off. The value property of the option button tells us whether a button was selected by the user. If the value property is true, the user selected that button; otherwise, its value property is false. Check Boxes: Check Boxes differ from option button in that, regardless of how many Check Boxes one places on a form, they can all be turned on and off independently.
If the user has selected Check Boxes, the value property switches to true. It stays true until the user deselects that box. List and Combo boxes: Use list boxes when we have a fixed list of choices. Visual Basic automatically adds vertical scroll bars when the list box is small for all items it contains. To allow users to input data as well as choices from a list, we use a Combo Box. The database is the actual data. It is the database that you will be accessing when you need to retrieve data.

Thus a new software has been proposed to reduce manual work, improving work efficiency, saving time and to provide greater flexibility and user- friendliness as the system previously followed was totally manual one with lots of errors. This new system is built with the following objective: 1 Information retrieval will become easy.
Whatever be the process involved in the system were done through register files. There were lots of complexities involved in the system. When any customer takes new connections then separate files were maintained. The manual work processes was time consuming and hence slow.
