The logical model will usually come first and represents the implementation nonspecific data requirements while the physical model covers the implementation specific details used to implement the database.

Physical Database Model Physical database modeling deals with designing the actual database based on the requirements gathered during logical database modeling. During analysis the conceptual process model evolves into the detailed functional requirements or logical process model. Both the logical and physical models represent design layers in the application development process.

How should a process be named. The logical Database Model describes data and not how they are implemented. During physical modeling objects are defined at a level called a schema level.

Define what is meant by a data flow in a process model. The main difference between data modeling and process modeling is that data modeling is the mechanism of creating a data model for an information system while process modeling is the mechanism of classifying the similar processes together into a model. One big difference between logical and physical data models is that we now need to use table and column names rather than specifying entity and attribute names.

The logical model enables you to represent business information and define business rules. Distinguish between logical process models and physical process models. Distinguish between logical process models and physical process models.
