What is a relational data?

A relational data is a set of data that have a certain pre-defined structure. Once this data structure (aka, data schema) is enforced on data then we can start talking about a relational database.

Thus, a relational database (DB) is a collection of data items with some pre-defined relationships. These data items are organized as a set of tables with columns and rows. The tables are used to hold a similar type of information object to be represented in the database.

WHAT is relational data storage in azure?

In Microsoft Azure, relational data could be stored in different forms and shapes. The early approach of storing and running relational databases has been accomplished through Virtual Machine (VM) instances. However, this approach brought a certain operational overhead and required specialized skills within the team to manage those VMs properly.

Nowadays, we could run the relational databases as a managed service (aka, PAAS) in the cloud. In other words, Microsoft Azure helped to offload operational overhead associated with the management of VMs that are assigned to run your database services. All this became possible by the introduction of managed relational Azure Database services like SQL, MySQL, PostgreSQL, and MariaDB.

In this study guide, you will learn about these managed, relational DB services in depth.
