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.
Alain Lefebvre
In 1990, Jean Rouveyrolles and Alain Lefebvre founded the company SQLI. In 1995, he directed the technical strategy of SQLI Group Intranet. This involved the introduction of the company to the new market of Euronext Paris in July 2000, SQLI then having 700 employees. This IPO was successful during the early crash of the bubble Internet. This was one of the few company "Internet" to have succeeded / survived the burst of the Internet bubble.
