1. 4.0 Theoretical Framework
In this chapter the proponents will present the theoretical foundation of the study. When we say
theoretical framework it is the structure that holds or supports the fundamental principles of the
study.
4.1.Information System
Information systems inter-relate with data systems on the one hand and activity systems on the
other. An information system is a form of communication system in which data represent and are
processed as a form of social memory. An information system can also be considered a semi-
formal language which supports human decision making and action.
4.2. Users of system
Admission: He/she is the one who receive inquiries.
Registrar: He/she is the one who transfer data to admin.
School/dean: The one who read and denote data to paper works.
Students: The target of current system.
4.3 database management system- asoftware system that facilities the creation and maintenance
and use of an electronic database.
Database Management System – software that mediates access to, additions and deletions of, and
change in data contained in a database, so as to store and access data efficiently and control
which data particular programs or individuals are allowed to use.
4.4 Entity-Relationship Diagram
An entity-relationship (ER) diagram is a specialized graphic that illustrates the interrelationships
between entities in a database. ER diagram often use symbols to represents the three different
types of information. Boxes are commonly used to represent entities. Diamonds are normally
used to represent relationships and ovals are used to represent attributes.
Entity- the entity is a person, object or event for which data is .
Relationship- is the interaction between the entities.

2. Attribute- is a specification that defines a property of an object, element etc.
4.5 Normalization
Is the process of efficiently organizing data in a database .There are two goals of normalization
process: eliminating redundant data (for example, storing the same data in more than one table)
and ensuring data dependencies make sense (only storing related data in table). Both of these are
worthy goals as they reduce the amount of space a database consumes and ensure that data is
logically stored.
*DFD (Data Flow Diagram) Is a graphical reprensentation of the flow of data through an
information system. It is set of process and each process perform their function and describes
specifies steps performs by a process to achieve its expected response.
