Database design is defined as a collection of steps that help with designing, creating, implementing, and maintaining a business’s data management systems. The main purpose of designing a database is to produce physical and logical models of designs for the proposed database system. A good database design process is governed by specific rules. The first rule dictates that redundant data must be avoided; as it wastes space and increases the probability of faults and discrepancies within the database. The next rule is that the accuracy and comprehensiveness of information is extremely imperative. If the database contains erroneous information, any documents that fetch data from such a database will also include inaccurate information. Consequently, any decisions based on those documents will be misleading, thus, increasing the importance of a database design that caters to all of the above rules. So, how can you ensure that your database design is good? A well-designed database is the one that: Distributes your data into tables based on specific subject areas to decrease data redundancy Delivers the database the information needed to link the data in the tables Provides support, and guarantees the precision and reliability of data Caters to your information processing and reporting requirements Functions interactively with the database operators as much as possible
