Power Objects is a front end tool. Oracle Objects are objects used to interface to the Oracle Database. You still need to use a Front End tool like VB or DELPHI. Instead of using CLI you would use Oracle Objects.

Yes.

>3) does PO support multiple inheritance ?

To a certain extent. You will be able to create what are called application objects with method code, and will be able to drag and drop them on to a form. This holds for objects like Push Buttons, Telephone Entry Box etc. Multiple inheritence in the classical sense is not supported. But you could create a user class of a form with other objects in it, then instantiate it to create an object.

Very similar to VB.

Not at this time. Only under Windows 3.X for now.

You can use OCX's. You have to import them into PO. They appear in the tool box. Then you would use them in a normal fashion. You can also create OLE objects. You can only embed them not link them.

>7) which rdbms will be supported but ms-sqlserver or sybase?
> odbc ? what's blaze ? what about ibm's db/2 or gupta's sqlbase ?
They will have native drivers for Sybase and Sql server. DBLIB only for now. Blaze is the local engine that comes with PO for stand-alone development.

>8) when will PO be released and what's the price (like visual basic) ?
It is in beta now. Probably september/october time frame. $399 for standalone, and something more for a client server version.

>11) does PO support oracle 7.1 sql-syntax completly ?

Too early to tell.

Not that I have seen.

>14) don't take this last question too serious:

We have seen a few guys that are interested..

Hope this helps..
