Logical Design: Logical design is used to translate the Conceptual design into the internal model for a selected DBMS (such as DB2, SQL Server, Oracle, I MS, Inf ormix, Access, Ingress and so on). The logical data model defines the structure of the data elements and set the relationships between them. Some methodologies merge the logical design phase into the other two phases.

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. 68 14
Can it vary in number independently of other entities? Conceptual ERD is the simplest model among all.Note: Conceptual ERD supports the use of generalization in modeling the ‘a kind of’ relationship between two entities, for instance, Triangle, is a kind of Shape. The conceptual schema must adhere to the data independence requirement.
