A database
model shows the logical structure of a database, including the relationships
and constraints that determine how data can be stored and accessed. Individual
database models are designed based on the rules and concepts of whichever
broader data model the designers adopt. Most data models can be represented by
an accompanying database diagram. The most popular example of a database model is the relational
model, which uses a table-based format.
