I've "Google" how to connect "TDSProviderConnection"
the "SQLConnection" property a "TIBCConnection"
Most have not found a way to do this
've looked at this link:
http://docwiki.embarcadero.com/RADStudi ... plications
I did not think anything more about it.
And I do not use the "TSQLConnection" with the drivers you
I want to use direct route "TIBCConnection" and "TIBCQuery"
I would like if you could please send me examples of two basic connection
Server and Client with IBDAC.
Grateful.

I recommend you to use the following article:
http://blog.devart.com/using-dac-produc ... pment.html
in which use of UniDAC with DataSnap is revealed in details.
To use IBDAC with DataSnap, replace the TUniConnection and TPostgreSQLUniProvider components with TIBCConnection, also replace TUniQuery and TUniStoredProc with TIBCQuery and TIBCStoredProc respectively.

Would you like a little project

The DataSnap technology involves three–tier architecture. To connect the DataSnap client with the DataSnap server, a native protocol is used, which is implemented by the TSQLConnection driver only. Therefore you cannot use our components for this purpose.
For connection with the database, the TUniConnection/TIBCConnection component is used, that is described in the blog.

Yes I understand you could post two more example of a server and a client and post on blog for better learning.
Grateful.

Please clarify what is unclear for you in the article and what difficulties you are encountering when migrating from UniDAC to IBDAC.

TSQLConnection implements a native DataSnap protocol to connect to the DataSnap server. And you cannot use TIBCConnection for this purpose in any way.
