<translate>== What are databases? == <!--T:1-->

<!--T:2-->

For our purposes, databases organize, represent, store, and make-searchable information.

<!--T:3-->

There are many kinds of databases. You might have heard about &quot;relational databases&quot; because they are very common and display information in tables (rows and columns), like a spreadsheet.

<!--T:4-->

As databases have advanced, programmers have been able to associate data with specific entities like people (ex. &quot;Person A&quot; has an address, age, occupation, etc.)

<!--T:5-->

This is possible by using '''unique identifiers''' (and '''identifiers''' in general) to describe relationships.

<!--T:6-->

Document-oriented databases are designed to structure data this way. Wikidata is a document-oriented database.
