There are two ways the adapters belonging to Adapter Pack can be used by SQL Service Integration Services:
1. Using ADO layer built on top of base adapters. This option is available with SAP and Siebel adapters.
2. Writing custom SSIS task which directly invokes adapter to communicate with LOB system.
Option 1 covers all scenarios where data need to be moved from LOB system into SQL server. The reason being that ADO layer exposes only Query and Execute interfaces. Using these ADO interfaces, we can only pull out data from LOB system.
If usage scenario is such that data has to be loaded into LOB system, then option 1 doesn't help. But that is the not end of story. We can write custom SSIS task. This custom task essentially wraps the adapter as destination component. Once adapter is exposed as SSIS component, it is available for use in any SSIS scenario.
