Developing a Custom Connection Manager
Integration Services uses connection managers to encapsulate the information needed to connect to an external data source. Integration Services includes a variety of connection managers that support connections to the most commonly used data sources, from enterprise databases to text files and Excel worksheets. If the connection managers and external data sources supported by Integration Services do not entirely meet your requirements, you can create a custom connection manager.
To create a custom connection manager, you have to create a class that inherits from the ConnectionManagerBase base class, apply the DtsConnectionAttribute attribute to your new class, and override the important methods and properties of the base class, including the ConnectionString property and the AcquireConnection method.
Most of the tasks, sources, and destinations that have been built into Integration Services work only with specific types of built-in connection managers. Before developing a custom connection manager for use with built-in tasks and components, check whether those components restrict the list of available connection managers to those of a specific type. If your solution requires a custom connection manager, you might also have to develop a custom task, or a custom source or destination, for use with the connection manager.
