Edgar Frank "Ted" Codd (19 August 1923 – 18 April 2003) was a British computer scientist who, while working for IBM, invented the relational model for database management, the theoretical basis for relational databases and relational database management systems.
Formally, a "database" refers to a set of related data accessed through the use of a "database management system" (DBMS), which is an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data).

Database administration is the function of managing and maintaining database management systems (DBMS) software. Mainstream DBMS software such as Oracle , IBM Db2 and Microsoft SQL Server need ongoing management.
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
Sometimes the old "turn it off and on again" actually works. In this case, try completely signing out of your account then sign back in. Many times, this will help, especially in cases of bad passwords or some simple browser issues.
IBM's System R was the precursor of the SQL relational databases that have become a standard throughout the world. For Microsoft, he worked on TerraServer-USA and Skyserver. His best-known achievements include: ACID, an acronym describing the requirements for reliable transaction processing and its software implementation; Granular database ...
