A number of ex-IBM employees covered a wide range of topics about how IBM Research developed SQL and System R and the role that IBM's Research Division played in getting IBM to finally announce and deliver relational database products: SQL/DS and DB2. There is a lengthy discussion of Query by Example (QBE) by its creator and a discussion of why it didn't get accepted as a product by any of the IBM operating divisions in spite of its strong support of the relational model developed by Ted Codd. The dominance of IMS in IBM's thinking and its impact on the lack of resources assigned to relational products, particularly the concern for possible erosion of IBM's enterprise MVS position, was explored. The focus in IBM Research of providing software which could be turned into products was examined and its effect in lessening the true research type of projects in the Research Division. Various methods for integrating research and development activities in IBM were also discussed. The discussion also highlights the problem of inter-organizational communications in an organization as large (and as balkanized) as IBM.
