On the other hand, the conceptual data model shows a fundamental high level of design, while the physical data model gives a very detailed view of design. The complexity or difficulty and details increase from the conceptual data model to the physical data model. This generally helps us to understand how the model will be actually implemented in the database. Physical data model: It will be showing us primary keys, foreign keys, column names, column data types, table names.Logical data model: It will be depicting attributes, entity names, primary keys, entity relationships, and foreign keys in each entity.Conceptual data model: It will be just depicting entity names and entity relationships.We have three different types of data models. What are the different types of data models? The proposal through which data models are created is called data modeling. What do you understand by the term ‘Data Modeling’?Ī data model represents logical data model tools and physical data model: business requirements and database objects, respectively, required for a database and are essential in communicating and expressing the database objects and business requirements.
