Balaguruswamy, E and others : Dbase III Plus: A g, 9. Relational Model. Logical model - This stage is concerned with developing a database model based on requirements. 4. A strong database model will also enable various ways to manage, control, and organize the stored information to effectively execute multiple key tasks. Physical model - This stage implements the logical model of the database taking into account the DBMS and physical implementation factors. As a result, applications may need to issue fewer queries and updates to complete common operations. ce(s) but also the performance of the system.
