The database is the cornerstone of all database-driven applications. Databases are designed to offer an organized mechanism of storing, maintaining and retrieving information through tables. If you’ve ever used Microsoft Excel, you’ve probably seen data presented in the tabular format. Databases function in a similar fashion, only they’re much more powerful than a simple spreadsheet in the ways in which they can manipulate, organize and retrieve data. Here are just some of the things a database can do that would be difficult, if not impossible, for a basic spreadsheet:
- Locate and retrieve stored information that matches a certain criteria.
- Update records in bulk.
- Perform complex calculations quickly and efficiently.
In an e-commerce website, a database is where all products are stored which allows visitor to search products simultaneously and retrieve them quickly. The database can also contain the information of registered users, promotional offers, payment information and more.
