PostgreSQL: The world's most advanced open source database Main Phases of Database Design In the picture below there are the main phases of database design. Database design is connected with application design. The requirements and the collection analysis phase produce both data requirements and functional requirements. The data requirements are used as a source of database design. In parallel with specifying the data requirements, it is useful to specify the known functional requirements of the application. Note that some phases are database management system independent and some are dependent. Conceptual Design Once all the requirements have been collected and analyzed, the next step is to create a conceptual shema for the database, using a high level conceptual data model. The result of this phase is an Entity-Relationship (ER) diagram or UML class diagram. During or after the conceptual shema design, the basic data model operations can be used to specify the high-level user operations identified during the functional analysis.
