Titel: An Entity-Relationship Model Extended to Describe Historical Information
Sammanfattning: The ER model has proved a successful conceptual capture and modelling tool for the  relational data model. Much effort has recently been made to extend the relational  data model to describe historical information, but as yet little corresponding  development in ER modelling has been made. We describe in detail the various  temporal behaviours that entities and relations may exhibit, and apply the results to  enhance a binary ER model with temporal semantics, which may fully model a certain  class of historical relational databases.  Keywords: Data Models, ER Models, Temporal Databases, Historical Databases.
