SQL
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Ted Codd in the early 1970s. This version, initially called "SEQUEL" ("Structured English Query Language"), was designed to manipulate and retrieve data stored in IBM's original quasi-relational database management system, System R, which a group at IBM San Jose Research Laboratory had developed during the 1970s.
History of Microsoft SQL Server
With the release of Service Pack 3, Microsoft also released the first 64-bit version of the SQL Server for the Itanium IA-64 platform. (not to be confused with the x86-64 platform) Only the SQL Server relational engine and SQL Agent were ported to Itanium at this time. Client tools, such as Enterprise Manager, would still need to be run from 32-bit x86 clients. The first release of SQL IA-64 was version 8.00.760, with a build date of February 6, 2003.
