Creation of an
- To create an information system an initial study and following phases are need to be made by the designer because they will create an impact to the design of the
database . - The information is collected in order to establish details about the entities, relationships among the entities generated.
- Business rules that are shaped up through relationships, connectivity, and cardinalities are being obtained and collected through designer.
- When an information system needs to developed, the development approach will differ based on the viewpoint.
- The designer team will apply the design idea by using a design team.
- The design team will be grouped as system analysts in order to choose the best design approach for the database that is the team will decide whether the design needs to be in decentralized approach...
