👉 What Is a Query?

Query means a request for data from a database. Using a query allows you to review data from multiple tables simultaneously.

For database management, you’ll need to use a query language like SQL, AQL, Datalog, or DMX.

👉 How Do Queries Work?

Queries add meaning to the code so the system can understand and execute actions. Users and databases can exchange information as long as they use the same language.

👉 Query Languages

There are two types of query languages: Structured Query Language (SQL) and Not Only Structured Query Language (NoSQL). The main difference between them is the data structure.

👉 Query Examples

There are a lot of query commands for managing data in a database table. Learn some of the commands by watching this video.
