I seem to recall some discussion here a while ago that touched on the issue of record-oriented vs. set-oriented data structures. Very simply, what are some of the fundamental reference materials on this topic? To further clarify, I certainly understand the idea of SQL being set oriented, but many implementations I have looked at seem to access data that is ultimately stored in a relatively traditional record (or row) oriented structure. Many of the fundamental papers on SQL query optimization also present algorithms that rely on looping through and conditionally testing a series of records. Finally, are there any DOS C libraries or products that utilize this? Raima's acclaimed db_vista package claims to use a "network" (vs. relational) structure, yet just from its literature I looked at it seemed like it would support "set" queries very well. (Or am I way off base here?) Tom Rombouts Torrance Techie tomr@ashtate.A-T.com V: (213) 538-7108
