TIBOTable and TIBOQuery are TDataset descendants. What that means is
that you can use Delphi's TDatasource and data-aware components, also
any other third-party component.

TIB_Query is NOT a TDataset descendant, so you can't use Delphi's
data-aware components. It uses TIB_Datasource and the TIB_* visual
components.

My recommendation is yes change TTable to TIBOQuery. But, you can
also perform that gradually, by migrating your application from TTable
to TIBOTable, as a start. Then gradually change TIBOTable to
TIBOQuery. And, if some are there just to read data and is not
connected to a data-aware control, you could use TIB_Cursor, since it
has less overhead.

Since the application has been developed with Delphi's data-aware
components, use TIBOTable and TIBOQuery. Otherwise, you'll have to
change all the visual components, if you want to use TIB_Query.
