Which editor enables you to design and configure how the data gets loaded into the target data warehouse, and is used to design a graphical representation of the relation between the data source objects that are used to populate the data warehouse target objects. The editor provides a set of operators that you can include with the mappings along with standard or custom transformations if required, such as key look, generating sequence etc. It also enables validation and generation of the code used to populate the data warehouse target.

The Mapping Editor in OWB is specifically designed for creating ETL (Extract, Transform, Load) mappings that define how data flows from source systems to the target data warehouse. It provides a graphical interface to visualize relationships between source and target objects, includes transformation operators (key lookup, sequence generation, etc.), supports custom transformations, enables validation of mappings, and generates the deployment code. The Object Editor is for object properties, Code Editor for generated code modification, and Transformation Editor is not a standard OWB component.
