Version: GeneXus 16
With an example where we create a new category called “Tourist Site” and change the category of all the transactions that were “Monument” in Beijing to the new category, we introduce the business component as a data type created as mirror of the transaction, and usable through variables and their Save(), Load(), Delete() methods, as well as Insert(), Update(), InsertorUpdate(), Success(), in any object. A comparison is made of the update through the transaction against the update through the business component. An explication is made regarding the need to use the Commit command.
