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.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
