A database design is a structured collection of records, files, or data that is stored so a program can use these items to answer queries. A database is a collection of records that can be structured to provide a schema for the users. A schema is what explains the objects depicted in the database and the relationships that they have. Most users of databases usually have a task to complete and planning the database design can be an important foundation for the design and functionality.

When planning to create or purchase a database management system, users might need to be questioned as to what they need or expect as the end results. Databases are used to store, change, and retrieve data in nearly every type or business. By getting users involved in the creation, the database will be able to provide information and reports that the users expect to get.

A good starting point is to outline reports that are needed and to learn what limits might be put on the use of the database information. The selection of criteria might also play a role in which the data is sorted or queried. A list of all the fields needed is also a parameter to help establish what will be needed. A good rule is to try and make tables and have each table self-contained so that redundant fields might be eliminated. An excellent database management system can supply ways to interactively enter and update the database while allowing a user to interrogate it.

The next important criteria are to assign key fields. Key fields are column or columns that users can reference any given row in a table. Users can also set up table structures by deciding on relationships between tables. A well-structured database can create relationships between entities so that desirable information can be retrieved.

After the planning is complete, the design process should become easier because of the knowledge of how to use the fundamentals of a database. By putting all the pieces together tables, forms and reports can now be created. When the final process is complete, test and hunt for bugs until the desired results are achieved. As users continue to retrieve reports and data, they will find new uses and needs that will constantly change. A database will probably be revised and redesigned in coming years for the users needs.
