Analysis Services has three programmatic interfaces that you can use from your analysis application. The first two interfaces are client-side interfaces: ADO MD and OLE DB for OLAP. Both of these programming interfaces offer functionality for data exploration, metadata exploration, write-back capabilities, and read-only analysis functions. Only the write-back capabilities affect the contents of the cube that other users in the system share. If you want to make other types of changes to Analysis Services data programmatically, you have to use the administrative programming interface Decision Support Objects (DSO). DSO lets you create and alter cubes, dimensions, and calculated members and use other functions that you can perform interactively through the Analysis Manager application.
