Source definitions : Definitions of database objects such as tables, views, synonyms, or files that provide source data. Target definitions : Definitions of database objects or files that contain the target data.
Mappings : A set of source and target definitions along with transformations containing business logic that you build into the transformation. These are the instructions that the Integration Service uses to transform and move data.
Reusable transformations : Transformations that you use in multiple mappings.
Mapplets : A set of transformations that you use in multiple mappings.
Sessions and workflows : Sessions and workflows store information about how and when the Integration Service moves data. A workflow is a set of instructions that describes how and when to run tasks related to extracting, transforming, and loading data.
