4.2. Database Building
4.2.1. Conceptual Design
The conceptual design of database is the result of the first understanding of the application and illustrates the application at its simplest. To answer the
question those arise during the need assessment, conceptual design will defines the objective of the database and the data need which required in the system.
Context Diagram
The context diagram is the highest level and represents the overall system, means context diagram shows all the external entities that interact with the system
through data or information flow over the system. The Context Diagram for this study shows three main entities and what they currently share in the way of
information; administrator, data source and user Figure 8.

Entity Relationship Diagram
On Conceptual design, the master data list table would be follow by the design of Entity Relationship Diagram ERD of the database. ERD model
contains components of entity set including their relationship set with their attributes that represent all facts from part of the real world. This diagram also
describes cardinality, the number of possible relationship of each entity. There are three type of cardinality, namely one to one 1:1, one to many 1:M and many to
many M:N. Figure 9 show ERD of this system.
