Dear Smalltalker, I'm trying to get into Smalltalk a bit more seriously. I'm especially currently trying to get into Seaside programmming and the persistence of Objects. I found GLASS, which seems to be remarkabel in that aspect. Now I wonder
1) How does one do versioning in Smalltalk. AFAIU it seems, one files out ChangeSets which then can be read in in another image. Am I wrong about that?
2) How does one Data Migration in Smalltalk? I just know it from Rails, where one has migrations, but how's that done in the Persistence layers of some Smalltalk. E.g what happens if I add or remove instance variables?
There are somewhat related question but more about GLASS. I read teh gemstone soup up and down, and was able to install the Web Edition on my System also. It was a few days work but I learned a lot. However I found just a few videos about Gemstone, but not more "serious" use (with more database related stuff, scheme changes etc) Would you mind to share your experiences?
Regards Friedrich
