A Brief History of SQL

  • Just wanted to add a link to a resource that most authors refer to as not (fully) available online.

    A Relational Model of Data for Large Shared Data Banks by E. F. Codd


    I think this is the full text.

    For those who are interested.

  • Wonderful article. I was searching for a article like this for long time.

    Great work. Congrats

  • I felt the content was interesting. It sure would have benefitted from a good proofreading however.  One more example of shoddy publication.

  • I liked the article. It was easy to understand, so I don't think any typos got in the way. Even Frank's signature was intriguing:

    "Frank Wenn Englisch zu schwierig ist?"

    So I took a look at the site (http://www.insidesql.de). Frank, judging by the first sentence, German doesn't seem to be very different from English:

    "Hier finden Sie zahlreiche Artikel, FAQs, Links, Tips und Tricks rund um den Microsoft SQL Server."

  • nice article but something is missing:

    From Wikipedia, the free encyclopedia.

    "Sybase SQL Server" was the name of Sybase Corporation's relational database product.

    It was originally created for UNIX platforms in 1987. In 1988, SQL Server for OS/2 was codeveloped for the PC by Sybase, Microsoft, and Ashton-Tate. Ashton-Tate divested its interest and Microsoft became the lead partner after porting SQL Server to MS Windows NT.

    Microsoft and Sybase sold and supported the product through version 4.21. In 1993 the codevelopment licensing agreement between Microsoft and Sybase ended and the companies parted ways.

    In 1995, Sybase released SQL Server 11.0. Thereafter, it decided to better differentiate its product from Microsoft SQL Server by renaming it to Adaptive Server Enterprise in versions 11.5 and beyond.

    Further History... Sybase was founded by Bob Epstein, the architect of a product called the Intelligent Database Machine (IDM) from Britton-Lee. This was a computer that only did relational database. It used IDL as its native language (similar but not identical to SQL). The architecture of that product was used as the starting point for Sybase, which began development from 1984(?). Beta testing of Sybase's first product started in 1986.

  • "So what’s next? Well, at a minimum SQL4 is due to be released in this century."

    SQL:2003 has already been published.


     Yet another standard for vendors to ignore.
