SSAS 2008 Upgrade Consideration: ODBC Data Sources from Analysis Services 2000 are not migrated
ODBC or Open Database Connectivity is a platform neutral, universal approach for providing an Application Programming Interface (API) to access relational database management systems. ODBC was an early modular approach to enable database access. The ODBC library itself is an independent Operating System (OS) component which acts like a bridge passing requests from the consuming application to the corresponding ODBC drivers.
