Next, the designer chooses a data model, and by applying the concepts of the chosen data model, translates these requirements into a conceptual schema of the database. Entity type - Entities can be classified into different types. In the logical-design phase, the designer maps the high-level conceptual schema onto the implementation data model of the database system that will be used.
