Databases store information in a structured format that allows for rapid search and retrieval. There are many uses for databases, but some of the more common applications are membership rosters, product catalogs, and document libraries.
Integrating a database into your website presents the opportunity to create compelling interactive features, allowing users to search for information, and allowing you to collect information.
When a database is integrated into a website, the web pages viewed by users display information that is stored in the database. The information that is stored in the database can be updated at any time, and the web pages that are linked to the database display the updated information. In addition to viewing information coming out of the database, users can also be permitted to update information in the database by entering it into forms in your web pages.
Databases are a part of most web applications.
