<div>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...</div>
<div><br>
</div>
<div>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.</div>
