SQL

SQL(Structured Query Language), is a language designed to allow to users query, manipulate, and transform data from a relational database . SQL databases provide safe and scalable storage.

Relational databases

 A relational database represents a collection of related (two-dimensional) tables. 

Relationships between tables allow you to organize your database and avoid data duplication

Some sql commands :

• Create a database ` CREATE DATABASE database_name `
• Delete a database : ` DROP DATABASE database_name`
• Create a table in a database. : ` CREATE TABLE “table_name”(“column_1” “data_type_for_column_1”,”column_2” “data_type_for_column_2”,… ) `
