SQL Server DAC / ADO Components

Hi,

i 've found CoreLab's SQL -Server Data Access Components at Delphi 2006 Partner CD too. Please allow me 2 questions :
- What are the differences between CoreLab Components and Borlands(?) ADO Components ? Well, CoreLab does'nt use ADO, ok, but may i use CoreLab Comps in an similary way ? (Btw, i would be happy if i hav'nt to care about different ADO versions at different Machines anymore

)
- Is it really free if i install from Delphi CD or should i register in future for getting updates & support (i think, you need some money for further development) ?

Thanks for answers,
Tino

An important matter is that ADO provides a universal data access and hence (like most of universal tools) yields to any specialized on in several respects. First of all, it affects performance. You can see Performance project from SDAC\Demos\Win32\Performance to find out yourself - ADO is inferior to SDAC at different tests from 1.5 to 20 times. Beside that, SDAC interface (run-time and design-time) is focused on working with specific features of SQL Server.

Yes, you can. Interface of SDAC is similar to ADO.

You should register SDAC to use it. There is a trial version on the companion CD.
