To clarify, 500 photographs each about 300k is the total number of photo's
for all 15 records.

I was wondering about the capacity of TClientdataset for in memory tables. I have only 15 records but each record will have a large amount of data including photographs. Could I use TClientdataset for this application? If not, what would you suggest as an alternative. This is just a small desktop
application and I am trying to keep it as simple as possible. Just one screen to input data. Probably just 2 files. One for text and the other for the pictures if I decide to use them. Previously all I've used is the BDE with Delphi. Thanks.

That is 150 mb of memory just to hold the photos. I would not use a CDS
for that. Use a database such as Advantage Local Server (free), DBISAM,
or NexusDb.

I see no value in stuffing the photos themselves into a CDS. Why not keep
the photos separate in their native format and use the CDS to store the
location of the photo, and things like caption, date, location taken, etc.

I was considering that too. This application is for a multi-party lawsuit
and involves expert's photo's taken by an engineer so I believe there is
value in embedding them in a database so they cannot be easily tampered
with. Of course an XML TClientdataset would be a poor choice too. I would
have used the binary version. In the end I will probably go with the local
Advantage database.
