How to Develop a Relational Database for a Company or Business
Databases are a mainstay of the business world, and for good reason. Database software can be used to create everything from a detailed list of employees to an interactive order database that product managers can use to track the most popular products and determine which products need to be restocked. Creating a relational database is an excellent way to improve the efficiency of any business and reduce the costs of doing business.

Map out the tables you wish to include in the database and how those tables relate to one another. The relationship between the tables is the heart of a relational database, so it is important to look at how those tables come together. For instance, a database devoted to employee information might contain a table for employee data like name, date of birth and hire date, along with another table listing the dates and results of each performance review. The common element between these two tables would be a unique field such as the employee number or Social Security number, and that field would be used to link the two tables.

Use the relationship builder function in the database program you are using to establish the relationship between the various tables in the database. The exact location of this relational database will vary with the software package you are using, but the concept is the same.

Create a query that uses linked data from each of your linked tables. One of the biggest advantages of building a relational database is the ability to combine fields from several different tables into a single query or report. Each time this query is run, the results will be updated based on any new information entered into those tables.
