Ensuring Transaction Integrity


You are familiar with individual data source operations that insert, update, or delete data source segment instances. However, most applications are concerned with real-world transactions, like transferring funds or fulfilling a sales order, that each require several data source operations. These data source operations may access several data sources, and may be issued from several procedures. We call such a collection of data source operations a logical transaction (it is also known as a logical unit of work).
