An ABL ProDataSet is an in-memory relational data object that can encapsulate one or more ABL temp-tables (sets of data rows) and any parent-child relationships among them. It also includes mechanisms to track changes, which facilitates synchronization with any data sources used to initialize it. In effect, a ProDataSet models a relational database, its entity relations, and its change state in memory. Because of the power and efficiency with which it can organize and communicate complex relational data, the ProDataSet is a primary mechanism for bundling and passing complex data within applications that conform to the OpenEdge Reference Architecture (OERA).
