It does; it is also available as a TechInfo sheet ( It doesn't discuss a transition involving Midas, though. Insofar as a transition from TQuery to TIBOQuery is involved, you are looking at a very straightforward conversion. Conversion time for IBO is minutes, compared with days or weeks for IBX. Straight off, the only recoding required will be to open the connection and activate any datasets you might wish to have open at startup (6 lines of code in your FormCreate).

Performance improvement will depend a lot on your architecture. If you have the "classic BDE" picture involving uncontrolled fetching and a lot of dependence on iterating through datasets on the client side, you can impose the same overhead on an IBO app if you wish and not notice much improvement in performance. If you want to work towards a more server-centric approach, then IBO offers an enormous amount of encapsulation that simply isn't available with BDE or IBX and the performance effects will be dramatic.

Actually, it is not free. It is subject to a one-time subscription of $29.50.

On the IBO website we have a considerable body of on-line FAQ which is keyword-searchable (powered by IBO, of course!)
