1.8 SCOPE OF THE STUDY:
This project seeks to design and develop Personnel Information System. Our focus is on National Population Commission. Our major area is to identify and modernize the specific function of Admin and Supply Department as regard to the management of personnel information. The software will be able to complement personnel database with payroll database. The sample size will be the staff of National Population Commission Enugu state office. The design will have three levels of users. They include:
• AN INDIVIUAL USER: Here an individual is able to view his records.
• THE ADMINISTRATIVE USER: Here the administrator has access to all the users' record of the department.
• THE SUPER USER: Here the officer has access to all the users of all the departments. The individual user can login and access their data/records only.
1.9 OPERATIONAL DEFINITION OF SOME TERMS:
Application:
An application is the executable file and all related files that a program needs to function which serve common purposes. The word is sometimes used synonymously with program.
ASCII:
This is an acronym for 'American Standard Code Information Interchange'. It is used to describe the byte values assigned to specific character. For instance, the letter 'a' has ASCII code of 65.
CLIENT:
1 Is anything that requires the service of something else. Example, in Object Pascal, a client is any code that uses one or more features of an object or unit. In windows, a client is the code that makes use of windows Application Program Interface (API).
2 Is a database system, in which a workstation connected to a server can request for data from the server. The client workstation can process data locally and write it back to the server.
COMPILER:
This translates a program source written in a high level language to an object code which consists of instructions that the computer can understand.
COMPONENT:
The element of visual basic application ionized on the component palette in the visual basic programming environment. Component including forms are object one can manipulate. It is always self contained and provides access to its features through properties.
DATA ACCESS COMPONENT:
Data objects are based within a visual basic program to manipulate database as well as the tables and indexes within the database. The data objects are the representations (in program code) of the physical database, data tables, fields, indexes and so on.
DATABASE:
A collection of operational data of organization stored in related tables.
DATA CONTROL COMPONENT:
Data control component means a visual basic component that enables a developer to create the interface of a database application.
DATA SET:
This is a collection of data determined by a Ttable or Tquery component. A dataset defined by Ttable includes every row in a table and dataset defined by a Tquery contains a selection of rows and columns from the tables that meet the condition specified in the query.
END USER:
This is a member of an application's intended audience synonymous with user but emphasized the fact that the programmer is not the user. According to Delphi document, end user is referred to as the users of application developed in a programming environment such as Delphi.
EXCEPTION, EXCEPTION-HANDLER:
An exception is an event or condition that if it occurs, breaks the normal flow of execution. Code assigned to resolve the situation in run-time environment that raises the exception and/or restores the environment to a stable state is called exception handler.
EVENT, EVENT-HANDLER:
Event is a user action such as a button click or a system occurrence such as a preset time interval recognized by a component. Each component has a list of specific events to which it can respond. Code that is executed when a particular event occurs is called an event-handler.
