From the Yellow Pages and your household inventory to employee records for companies, databases make it easier to manage information. Unlike file holder methods that require you to copy files from one location to another for every different type of data, databases have the ability to store and retrieve information in a quick and organized manner. In addition, the database system takes care of backups and recovery.
A database can handle large amounts of data and support scalability to accommodate business growth. In addition to ensuring that relevant information is easily available, databases can help streamline business processes by eliminating duplications and inefficiencies. By allowing multiple departments to access and share information, databases enable cross-functional collaboration and foster communication across teams.
The main function of a database is to store, organize and report on information in an integrated way. To do this, databases separate information into tables based on specific types of information, such as products or customers. Each table is then connected to other tables using field values called foreign keys. The primary key for each table is usually an identifier that will not change, such as a unique product or order number.
To create a database, first brainstorm what kinds of information you will need to record. This will help you decide how to divide your information into tables. Next, you will need to determine the details of each table, such as the name and size of the fields. Try to limit the number of different facts that you combine in a field; for example, avoid recording a supplier’s address in both the suppliers and products tables.
