How does a database work?

TechnologyLesson on requestFree to read

Quick answer

A database works by storing information in an organized structure — often tables of rows and columns — so it can be quickly searched, updated, and retrieved. Software called a database management system handles storing the data and answering queries.

Step by step

  1. Data is stored in an organized structure, often tables.
  2. A management system handles storage and retrieval.
  3. Queries (often in SQL) fetch exactly the data you need.
  4. Indexes make searching huge amounts of data fast.
