One advantage of being an antedeluvian sauroid is having been there when ancient history took place.
In the 1950s and early 1960s, computing was new and exciting. Many groups were formed to study and talk about various aspects. ACM, SHARE, GUIDE, etc. Together they put on expos called "Joint Computer Conference", Spring and Fall. I last attended the 1969 Fall Joint in San Francisco, where I gained some notoriety by out-hustling the bumper-pool Bunny at the Playboy club.
Two organizations that came out of all this collegialism were Committee on Data Systems Languages (CODASYL) and Data Base Task Group (DBTG). DBTG specified a database model, which was implemented by at least two colleges, Princeton (RAMIS II) and UNC (SAS). This was a few years before Codd & Date's relational model, but there is a strong resemblance.
SAS and RAMIS are so much alike that you can convert a retrieval command of one to the other just by moving a few lines of code around, which I have actually done.
SAS especially is still going strong. It has always been more powerful with statistics. If you are comfortable with the relational model and the statistics, it's a piece of cake.
If offered and accepting a gig, I would invest a Benjamin or two in manuals purchased from SAS Institute.
