Hi 
I don't known either. Do you translate names such as "Writer" and "Calc"?
If so then "Base" should be translated but it's difficult to know
which way to go with it. Base as in solid foundation perhaps?
The "Table"s are a lot like the work-sheets in Calc. They hold all
the data but Queries and Forms and Reports are used to give different
views of that data, in much the same way that different windows in a
house give you different views of the outside world.
Queries are displayed as tables but in "design view" they look a LOT
different.

You know in Calc when you press on the f(x) button to build up a
formula? It's a bit like the same sort of idea but displayed
differently. It builds up an sql statement but unlike in Calc you
never see the actual sql in design view
Sorry!! I don't think any of this helps! It might even be leading
you astray a bit
Which language are you translating into?
Apols and regards from
