Physical database designing is a process that helps make descriptions of the execution of the database on secondary storage. This process describes the base relations, file organisations along with indexes which helps to gain efficient access to the data, any associated integrity constraints and security measures. The methodology is divided into two major parts, the first is to transform the logical data model for target DBMS, and the other is to design file organisations and indexes. Under the first one, the three steps are to design base relations, then the representation of derived data and the general constraints. Under the second step, there are multiple steps such as analysing transactions, choosing file organisation, choosing indexes, estimating disk space requirements, designing security mechanisms and user views, and monitoring and tuning operational systems.
