- Embedded SQL for C.
If you happen to be on a platform other than Mac, you also get JDBC.
What else would you like to see in a CSDK bundle? Maybe I'm getting spoiled but looking at Microsoft and Apple, if you get an SDK you actually get a a real toolkit, something that also helps you build rapid prototypes, or even full fledged applications. I honestly think that IBM has a solution there already too. The free version is called Data Studio, and with just a little tweaking IMHO, could be the exact gui programming tool I see missing from the CSDK bundle. Even then though, I think all we would see on Unix platforms would be JCC, JDBC, ESQL/C and ODBC, and the question then is "is that enough, or do you want more?"
Would PHP, Ruby, and perl be enough? What else could/should a developer want for a CSDK bundle? I want to hear you thoughts on the matter.
