These are rules and practices to follow, regardless of database structure type: In the planning phase, consider what functionality will be included in the database. It is important to start with a complete picture of the database structure, which can then be refined along the way. This will make working with the database much easier. Determine the necessary tables and fields. This is the most difficult part of the development process, one that requires attention to detail. Use a data modeling tool, preferably one that can create visual models of the database. This will help determine which specific information needs to be stored. You can use MySQL, Workbench, DBDesigner4, or Gliffy. Use a unique key for every record in a table. This will prevent data duplication. Grouping and separating data: Table fields should be organized as efficiently as possible. It is important to know when to combine them and when to keep them separate. Database normalization is a set of guidelines for storing information more efficiently.
