I agree that database adapters should be considered a core component
of the IDL suite.
The lack of an adapter encourages programmers to use IDL in
complicated ways. For example, I have used lock files to attempt to
block access to shared files over a network drive. I also had work out
a way to merge the contents of save files when two people are trying
to write at the same time. Needless to say, it was a complete
disaster.

I've see a few free database adapters floating around, but many of
them miss important features such as type conversion and string
escaping. I am concerned that this is going to make IDL look bad in
the longer term, because there will be a whole heap of applications in
the user community which are written poorly.

However, Michi, in your particular case I cannot see how you will have
a problem. AFAIK, you are simply implementing a patient selector for
DICOM files. I can't see why you have a problem simply caching DICOM
tags in a sav file. I have done this myself and it seems to work
reasonably well for a single user situation. If I were implementing
the same thing in Python then I would consider using freeze/thaw in
preference to SQLlite.

If you are doing anything beyond a patient selector then you would
probably need a database.
