IBM System R facts for kids
IBM System R was a very important computer program, like a super organized digital filing system, created by scientists at IBM starting in 1974. It was built at IBM's San Jose Research Laboratory. A smart scientist named Edgar Codd led the team. Their main goal was to bring his new ideas about how to store and organize information, called "relational databases," to life.
System R was a groundbreaking project because it was the very first time the computer language called SQL was used. SQL is like a special language that computers use to ask questions and get information from databases. Today, SQL is the main language used for almost all relational databases around the world.
This system also proved that relational databases could handle many tasks and process information very quickly. This was a big achievement back then. The clever ways System R was designed, and the smart computer "recipes" (called algorithms) it used to find information fast, helped shape how many other databases were built in the years that followed.
The First Users
System R was first used by a company called Pratt & Whitney in 1977. However, it didn't become super popular right away because it didn't work on the Unix computer system, which was becoming very common at the time.
