Sinopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In software engineering, an entity-relationship model (ERM) is an abstract and conceptual representation of data. Entity-relationship modeling is a database modeling method, used to produce a type of conceptual schema or semantic data model of a system, often a relational database, and its requirements in a top-down fashion. Diagrams created by this process are called entity-relationship diagrams,ER diagrams, or ERDs.
