SQL & PostgresFundamentals : What problems sql solved?. Intro with Postgres

SQL solve the data chaos. Prior to this standard :
- Each database has its own crypt language
- Database run in a specific hardware
- You need a dedicate engineer to effectively handles data

Postgres is just a flavor of this Structure Query Language which is a Relational (Table) database.

Which is good for handling structured and known relations.
