INTRODUCTION OF PROJECT
NEED OF PROJECT
As India rapidly moving toward evolution of mechanism, So as to meet the basic necessity we needs to travel from one place to another & only by air we can reach the required place/destination as early as possible.
So aircraft management that is airport management should be developed to meet the 21st century. Therefore, we should design our airport with well equipped technology. It will ease our transportation. By the help of this ‘Airways system’ software we can do all works as fast as we required.
Features of Visual Basic:
Visual Basic is a flexible, high level, structured programming language.
Visual Basic includes certain low level features that are normally available only in assembly or machine language.
Visual Basic is widely available, commercial interpreter are available for most personal computer, mini computers and main frames.
Visual Basic is largely machined independent. Programs written in visual basic are easily ported from one computer to another.
Your programs interface may include the familiar controls that window users already know how to operate-such as command buttons, option list, text boxes and scroll bars.
With just a few mouse actions, you can add any combination of these controls to a program.
As a result design tasks that used to require many hours of detailed programming efforts can how be completed in minutes.
In Visual Basic you can quickly design the visual elements of any new programming project.
The Programming Process:
These standards steps are to be followed while creating Visual Basic Programs:
1. Deciding what your application is do by crating an
overall design.
2. Creating the Visual Basic portion of the application (the serene and menus that the users will interact with)
3. Adding the Visual Basic programming language code to tie the Visual Basic elements together and to automate the program.
4. Testing the application to locate and remove any bugs.
5. Compiling the tested application and distribute the
compiled application to the end users.
Visual basic includes a special helpers system called a debugger that the programmer can use to help locate bugs that appear during testing. The debugger is an interactive monitoring system that you turn on and off inside Visual Basic that helps you locate statements that may contain bugs.
•Programming Maintenance
Apart from the bugs, the programmer has to maintain the program he /she has created. Program Maintainance is a term used for the updating of a program after the program after the program is put into use. This updating may be a result of the users request or a change in the way the program needs to operate.
•Project
A project is a collection of files that make up your application. A single Application might consist of several files and the projects is the collection of those files.
•Multiple Documents Interface (MDI)
It allows the application to contain multiple documents windows. In effect, this interface lets your work with several sets of data in multiple window within the program. Each document window is called a child window.
• Single Document Interface (SDI)
It limits the application take on a window Explorer- like interface with topic summaries in the left window an details for a selected topic in the right pane.
Why is System Analysis Necessary?
During system analysis some activities are carried out, such as problem definition, design, implementation.
Before designing the actual system/project, you should know,
1. What is the problem?
2. How to solve it?
3. What are the technical factors required?
4. What are its features and limitations?
If a system is designed without considering above activities then the system will not work properly to the satisfaction of user requirement.
So system analysis is necessary to design perfect and accurate system, which satisfies the user requirement.
Role of system analyst:
System analysis is central to the whole of system development. It includes gathering the necessary data and developing plans for new system. This is not an easy task because many people need to be satisfied and many conflicts resolved.
The system analyst is the person who guides the analysis, design and implementation and maintenance of a given system. In performing these four tasks, the analyst must always match the information system objectives with the goals of organization.
