when you have data for lookups, you should keep these datasets active,
as you probably will use these same data again. This will minimize
network traffic, server load, etc...
For these cases, the best solution is to use ClientDatasets, as you
can load the data in the ClientDataset and disconnect from the
database, keeping the data on the local memory.
