I wanted to start working again on creating educational content for users here and even otherwise. So I will share my learnings here. Today's topic is databases.

So, what are databases?

  • Database is any collection of related information.

  • Computers are great for storing data and information.

  • Database Management Systems (DBMS) make it easy to create, maintain and secure databases.

  • DBMS allow you to perform CRUD (Create Read Update and Delete) and other administrative tasks.

  • There are 2 main types of databases like relational (ex. Oracle) and non relational (ex. MongoDB) databases.

  • Relational databases use Structured Query Language (SQL) and store data in rows and columns

  • Non relational databases store data in other data structures like a JSON formatted object.
