Fully concur - one of the things I considered to write was someting along the lines of a vfp-like cursoradapter or the Dotnet Dataadapters to pipe the usual local list/tuple output of datastore connectors into SQLite cursors. Planned usage as local datastore and biz layer for dynamic app development. Benefits: much easier on memory usage to allow larger local datasets in apps, local datamunging with local lookup lists also in SQLite in SQL and with some additional planned goodies like targeting memory: or slower media via properties. Either in Javascript, Java or Python (the latter to be switched largely into Cython) to connect to their specific back-end-abstractions like DBAPI. And SQLite is also available on Symbian as standard for internal data tables and is also relatively errorfree due to longer usage time and large user base.

As Lianja promises to do much more (Replication...) than that I shelved the idea...
