Hi all,
Can someone tell me what COM/DCOM/ADO are?!! I heard about them but never been interacted with them. I need some introduction please.
Thanks
COM (Component Object Model)
Purpose
COM is a platform-independent, distributed, object-oriented system for creating binary software components that can interact. COM is the foundation technology for Microsoft's OLE (compound documents) and ActiveX® (Internet-enabled components) technologies, as well as others.
Where Applicable
COM objects can be created with a variety of programming languages. Object-oriented languages, such as C++, provide programming mechanisms that simplify the implementation of COM objects. These objects can be within a single process, in other processes, even on remote machines.

DCOM
Distributed Component Object Model
Definition is to long. Look in your MSDN Library for more on DCOM.

ADO
ActiveX™ Data Objects. A cross-language technology for data access that exposes an object model incorporating data connection objects, data command objects, Recordset objects, and collections within these objects. The ADO object model provides an easy-to-use set of objects, properties, and methods for creating script that accesses data in databases.
