Is SQL relational or non-relational?

Is SQL a non-relational database?

Non-relational databases are sometimes referred to as “NoSQL,” which stands for Not Only SQL. The main difference between these is how they store their information. A non-relational database stores data in a non-tabular form, and tends to be more flexible than the traditional, SQL-based, relational database structures.

Is SQL a relational model?

Is MySQL relational or non-relational?

Why is SQL called relational?

The name comes from the mathematical notion of “relation.” It all started with E. F. Codd who in 1970 (in the article A Relational Model of Data for Large Shared Data Banks) proposed something now called relational algebra as the mathematical foundation of databases.
