The logical data model drives the physical data model that is specific to a database product and is the detailed design document that guides the creation of the database and application software. The physical data design model involves translating the logical db design of the database onto physical media using hardware resources and software systems such as database management systems (dbms). Data modeling in software engineering is the process of creating a data model by applying formal data model descriptions using data modeling techniques.

Therefore, the main objective of this research is to represent different models of software In analysis modelling, information, behavior, and functions of the system are defined and translated into the architecture, component, and interface level design in the design modeling. Good data modeling and database design are essential to the development of functional, reliable, and secure application systems and databases that work well with data. Learning by building models • the software design process involves gaining knowledge about a problem, and about its technical solution.
