There is no built-in support for persisting collections in this version. What you could do in the meantime is save them in a single database cell as, say, a space-separated list of values. This will not work too well if you have thousands of values, but otherwise, it is quite easy to do in ODB. See the ‘mapping’ example for some sample code.

Can it persist classes using STL data types such as Map or is it limited to the basic C++ types in this version?

There is no direct support for relationships in this version but it is coming in the next release. The to-one relationship can be emulated by storing the object id and then manually loading the other end of the relationship. The to-many relationship is harder since there is no direct support for storing sequences either (also coming in the version).

How do you handle relationships? I couldn’t find anything on the docs.
