This document discusses Microsoft's integration strategy and Host Integration Server 2000. It provides an overview of Microsoft's approach to data integration, application integration, and network integration with non-Windows environments. Key capabilities covered include OLE DB and ODBC providers for accessing mainframe data, COMTI for wrapping mainframe transactions as COM objects, and the MSMQ-MQSeries bridge for messaging integration.
