Connecting to a distributed relational database

What makes a distributed relational database application distributed is its ability to connect to a relational database on another system.

There are two types of CONNECT statements with the same syntax but different semantics:

CONNECT (Type 1) is used for remote unit of work.
CONNECT (Type 2) is used for distributed unit of work.

For embedded SQL applications, the RDBCNNMTH parameter on the CRTSQLxxx commands determines the type of CONNECT. CLI and Java™ applications always use distributed unit of work because of the nature of the language.
