Distributed Unit of Work

For Distributed Unit of Work:

• Within a single unit of work, users or applications can read and update data on multiple systems. Each SQL statement can access one system.
• There are several RDBMS’s per unit of work.
• There is one RDBMS per request.
• There are several unit of work managers.

Distributed Unit of Work (DUOW) permits the same capability and functionality as RUOW, but allows the system connections to take place on an implicit basis. In other words, the SQL CONNECT statement is not required. The program still controls commit and rollback, and you must still make provisions for them at the program level.
