SQL created by EF Codd at IBM (see his paper the relational model) is [[Structured Query Language]], a language for manipulating large data tables within a database.  Most relational databases have sql embedded withing them.  Users ask for the data they write a "query" using sql and the database quickly returns the data.  Versant is an example of an object oriented database. OODB-s offer a different strategy than relational db-s that some claim can lead to much greater speed.  The market now seems to favor relational databases currently and only time will tell if OODB-s catch on.
