Data Model– Building Web Applications

Shilpa Rani

Abstract :

A data model describes the structure of a database, data relationships, data semantics and consistency constraints. In data model, an entity is defines as a type of object, and is simply an aggregate of named attributes, where each attribute is a primitive data element such as a number, string or date. Object database management systems add database functionality to object programming languages. The network model may have many different records containing unique identifiers, each of which acts as an entry point into the record structure. Record types are grouped into sets of two, one or both of which can in turn be part of another set of two record types. There is a hierarchy of parent and child data segments in hierarchical model.
