UniDAC vs SQL SDAC

[MatjazCof]

Can someone please clarify what is the difference between SQL Server Data Access Components and Universal Data Access Components.
The price confused me. It is the same, but UniDAC can connect to multiple database where SQL SDAC can connect only to MsSQL server. But the price are the same for both products.
I expect UniDAC would cost more.


Professional Edition with source code
UniDAC Professional Edition + Source Access*
$449.95 $1099.95 $1999.95

UniDAC allows working with a large number of databases, but it has limited functionality to work with each of them. SDAC allows working only with one database, but it operates with a richer functionality set. In order to balance their functionality/cost ratio, the prices were made the same.

Thank you.
Do you have compare table which would help me determine what are additional functionalities in SDAC?

To access SQL Server, UniDAC uses the same main modules that are used in SDAC. However, UniDAC has no support for some specific SQL Server features, that are supported in SDAC:

- ServiceBroker;
- ChangeNotification;
- the NonBlocking mode, in which an SQL query is executed in a separate thread;
- data types: geometry, geography, hierarchyid, and xml

Therefore, if you don't plan to use SDAC specific features, there is no difference between using SDAC and UniDAC.
