Online SQL Training
SQL draws its basic concept from relational model, which was first defined by an IBM based researcher, Dr. E. F. Codd. He wrote a paper, ‘A Relational Model of Data for Large Shared Data Banks’. This article attracted more people about the feasibility of this system in terms of commercial application. IBM started the System/R project in 1974 as the works of Donald Chamberlin and others led to the emergence of the SEQUEL, a Structured English Query Language. In 1976-1977, SEQUEL was completely rewritten to help with the implementation of multi user and multi table features. The revised system was renamed as SEQUEL/2 and eventually it came to be known as SQL.

In other databases, the data types and the SQL syntax might differ but you can learn them faster once the base knowledge is complete. While learning SQL you will learn about databases, their necessity, primitive methods and their disadvantages, advantages of databases.
