>Actually AFAIK, System/R was the first relational database implementation, done in IBM research in the late 1970s. SQL/DS was the first productized version (it ran on VM) and DB2 showed up on MVS/XA a little later - circa 1983.
Model 204 came out in 1973 (or 4). The only reason I know this is because my ex-wife's first database job was as an M204 DBA. - -teD I’m an enthusiastic proselytiser of the universal panacea I believe in! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
