Business Cycle Phases. Database design is a framework that the database uses for planning, storing and managing data in companies and organizations. Metaphors can be used to reduce the data pile and find patterns in it so that it becomes easier to connect data with theory. The conceptual database design phase starts with the formation of a conceptual data model of the enterprise that is entirely independent of implementation details such as the target DBMS, use of application programs, programming languages used, hardware platform, performance issues, or any other physical deliberations. Besides, database designers may also add primary keys, foreign keys and constraints to the design. 1. This design phase serves as input for the next phase of the model.
