Comparative Study on Extended Entity Relationship and Unified Modeling Language

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Entity Relationship modeling is the process of coming up with an abstract and conceptual representation of data. Entity Relationship diagrams ultimately model the databases. Entity Relationship model is generally better in relationship name and participation representation than the Unified Modeling Language diagram. In Extended entity relationship diagram is describing the data requirements for a new information system in a direct and easy to understand graphical notation. Unified Modeling Language has a direct relation with object oriented analysis and design to representation for the cardinality relationship compared with Entity Relationship diagrams. The fields are entities, attributes, relationship, cardinalities, identifiers to use the Extended Entity Relationship and Unified Modeling Language diagrams with the representing notation.
