Database Modeling Rules
The data model enables representation of the static structure of data at business level. A database is the object that enables storage and organization of data for use by programs corresponding to distinct applications, to facilitate the independent evolution of the data and the application programs.
You can connect a data model and associated diagram to a database. You can then create the corresponding relational diagram.
