In late 1987 Sybase and Microsoft launched into a partnership to produce and market DataServer, which used SQL, and ran on the OS/2 operating system. Over time many of these original vendor-specific extensions would be adopted by other vendors, eventually finding their way into the standard SQL language. This is what led to Sybase to develop the Transact-SQL language extensions to support their own RDBMS implementation. With the SQL language now being a standard, vendor implementations of SQL found it hard to support their product lines with only standard SQL syntax, therefore vendors started creating their own extensions to the SQL language to enhance their products. During this standardization process the official pronunciation for SQL was declared to be ess queue el, but many people still refer to it as sequel. In 1987 the International Organization for Standards (ISO) adopted SQL. With many vendors exploiting SQL, the language was standardized by the American National Standards Institute (ANSI) who defined the SQL-86 standard in 1986. In the 1980s many other products that used SQL came to market.

System/38 proved to be a viable offering that lead IBM to spend even more time and effort exploring other software applications that took advantage of SQL.

Shortly after the release of Oracle V2, IBM released its RDBMS known as System/38 which used the SQL language to manipulate data.

beat IBM to market place with SQL, and this wouldn’t be the first or last time that a company beat IBM to the market place on a technology product. In June 1979 they released the first commercially available RDBMS that used SQL, which was called Oracle V2 which ran on a VAX machine. They started developing a database management system they hoped to sell to the U.S. In the late 1970s a company called Relational Software Inc., which later became Oracle, saw the value of the relational database model and the SQL language developed by Chamberlin and Raymond. That is how the SQL language was now born. They shortened the name to just three letters, SQL. It was discovered that the name SEQUEL was already trademarked by a United Kingdom aircraft company named Hawker Siddeley, which caused IBM to change the name of this new data manipulation language. If you want to find out more information about the first SEQUEL rule set you can read a paper published by Chamberlin and Raymond, which can be found here. The original SQL code set identified a set of functions, and a set of simple and consistent rules. They invented this language to allowed programmers and infrequent database users to interact with data. They originally called this new coding language SEQUEL, which stood for S tructured E nglish Q uery L anguage. Boyce developed the first incarnation of the SQL language while they were working in IBM’s San Jose Research lab. It all began at a little known company called IBM in the early 1970s. Fasten your seatbelts while I crank up the time machine and travel back in time to follow the history of SQL and Microsoft SQL Server from its early years to where they are today.

Now let’s step back in time and discuss the history of Structured Query Language, or what most SQL Server professionals just shorten to SQL or pronounce like the second part of a bad movie and say sequel.
