Remarks
DDEX supports the concepts of data sources and DDEX providers. A data source represents a data source type, such as a SQL Server or Microsoft Access database (.mdb) file. A DDEX provider supports one or more specific data sources. On the other hand, each data source may have one or more DDEX providers associated with it.
A given DDEX provider supports one or more specific data sources. Further, a given data source may support any number of DDEX providers.
