 | | Oracle is often incorrectly cited as beating IBM to market by two years, but in a great public relations coup, beat IBM s release of the System/38 by only a few weeks. |
 | | It is often suggested that IBM was slow to develop SQL and relational products, possibly because it wasn t available initially on the mainframe and Unix environments, and that they were afraid it would cut into lucrative sales of their IMS database product, which used navigational database models instead of relational. |
 | | But at the same time as Oracle was being developed, IBM was developing the System/38, which was intended to be the first relational database system, and was thought by some at the time, because of its advanced design and capabilities, that it might have become a possible replacement for the mainframe and Unix systems. |
