Tend to disagree with both.
Use tables for smaller lookup tables. These are opened at startup and stay
open.
Grids are useful for viewing data but not for data entry. In Delphi 1,
grids were extremely noisy beasts that sent 20-30 calls to the database
every time you thought about pressing a hey or moving the mouse. This is no
longer the case.
Useful for where the user needs to view and select from a well formatted
list of records such as transactions for a single master.
Where the number of records are very large, say 20,000, then perhaps the
programmer should reduce by selection, but even so, the grid will only
fetch enough to display the records currently shown, fetching others when
needed.
