Abstract Database Systems has a practical‚ hands-on approach that makes it uniquely suited to providing a strong foundation in good database design practice. Database design is more art than science. While it’s true that a properly designed database should follow the normal forms and the relational model‚ you still have to come up with a design that reflects the business you are trying to model. This paper shows describes design process of database project. The importance of Completing the Design Process

Database Design Paper “A database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional‚ it must not only store large amounts of records well‚ but be accessed easily. In addition‚ new information and changes should also be fairly easy to input.” (tech-faq.com); to ensure usefulness over the long-term‚ databases should be built with high data integrity and the ability to recover data if the hardware fails.
