Designing Databases

Designing a database requires an understanding of the business functions you want to model. It also requires an understanding of the database concepts and features that you want to use to represent those business functions. Make sure that you accurately design the database to model the business, because it can be time-consuming to significantly change the design of a database after you implement it. A well-designed database also performs better.
