12.1 Brief History of SQL
The origins of SQL date back to the 1970s at the IBM Research Center. The language was initially developed by Donald D. Chamberlin and Raymond F. Boyce, who initially named it SEQUEL (Structured English Query Language). SEQUEL was a part of a larger project at IBM named System R, which aimed to design and implement a prototype RDBMS. The project was influenced by the relational model proposed by Dr. E. F. Codd, also from IBM, who set the foundational principles for organizing and interacting with data in relational databases.
SEQUEL was later renamed SQL due to a trademark conflict. Over the years, SQL has been adopted and expanded upon by different database management system vendors, such as Oracle, Microsoft, and MySQL. The standardization of SQL started in the 1980s, with the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) playing significant roles in this process.
