Hi Tiemo,

Originally, there were only the 'revdb_' commands and
functions. In Revolution 2.0, a number of synonyms
were added to make them easier to recognize and
understand.
The good news is that they're interchangeable: for
instance, if you have a database connection opened
with 'revdb_connect', you can use this connection ID
with the 'revDataFromQuery' function. The same goes
for all functions and commands that have to do with
cursors.
The not-so-good news is that this can cause some
confusion, as users aren't quite sure if one set is
deprecated and will go away in the future. And there
are some subtle differences where the 'revdb_' syntax
is a function, but the 'revXYZ' syntax is a command.

Personally, I still use the 'revdb_' set as I find it
easier to recognize that I'm doing something with the
database library external.
Maybe someday we'll get a proper namespacing feature
in the language and then there will be less confusion
- or just different confusion, as the case may be ;-)

Hope this helped,

Jan Schenkel.
