The first SQL model was developed by Ted Code, who introduced the ability of communication between different storage units. His idea was later acquired by Donald Chamberlin and Raymond Boyce and developed the model in the 1970s. However, the version at the time was referred to as SEQUEL (Structured English Query Language) specifically designed to help in data storage and retrieval. More modifications were made over the years in IBM, with the first being done in a laboratory in San Jose, California, United States, where the first subscript notation was introduced. After testing the effectiveness of the software in customer test websites, SQL was then developed for use commercially after its usefulness and practicality determined.
