Relational Database Design

The goal of a relational database design is to generate a set of relation that allows us to store information without unnecessary redundancy and also to retrieve information easily.

One approach to design schemas that are in an appropriate normal form. The normal forms are used to ensure that various types of anomalies and
inconsistencies are not introduced into the database.

Data Model

Data model is based on Data, Data relationship, Data semantic and Data constraint. A data model provides the details of information to be stored, and is of primary use to aid a computer software make-or-buy decision.

Data models are often used as an aid to communication between the business people defining the requirements for a computer system and the technical people defining the design in response to those requirements.

The relational data model is the most widely used data model, and a vast majority of current database systems are based on the relational model. The relational model was designed by the IBM research scientist and mathematician, Dr. E.F.Codd. Many modern DBMS do not conform to the Codd’s definition of a RDBMS, but nonetheless they are still considered to be RDBMS.
