Sql Database Design Tips – Database Design Normalization

The aim of relational database designis to generate a set of schemas that allow us to Store information without unnecessary redundancy or overhead and Retrieve information easily with accuracy.

Bad logical database design results in bad physical database design, and generally results in poor database performance. Both the logical and physical design must be right before you can expect to get good performance out of your database. If the logical design is not correct before you begin the design and development of your application, it might be too late after the application has been implemented to fix it. No amount of fast, expensive hardware can fix the poor performance caused by poor logical database design done by average database designer.
