Object-based models - data models, Database Management System

Assignment Help:

Object-based Models: Use objects as key data representation components.

Examples:-  

  • Entity-Relationship Model: It is a collection of real world objects known as entities and their relationships. It is largely represented in graphical form using E-R diagrams. This is very useful in Database design.
  • Object-Oriented Model: Tells the database as a collection of objects that haves both data members/values and operations that are allowed on the data. The constraints and interrelationships are executed through links, objects and message passing mechanisms. Object-Models are effective for databases where data interrelationships are difficult, for example, Computer Assisted Design based components.
