How to get SQL Assignment Help Online?
Structured Query Language or SQL, initially known as SEQUEL (Structured Query English Language) was developed at IBM by Donald D. Chamberlin and Raymond F. Boyce in the early 1970s. Relational databases like MS Access, Oracle, SQL server etc., use SQL as their standard database language.
SQL is a declarative programming language. A declarative programming language describes what you do not how you do that task. SQL statements only describe what you want to retrieve or insert or delete from a database. However, they do not tell how to do that. SQL is often referred as a query language as we use it to query the database.
