The Loader command allows you to process load files to add objects and relationships to the SmartPlant Foundation database. The Loader connects with the data warehouse and acts as a middle tier between various data sources and the calling program objects. Loader reduces the number of load programs by reusing the calling program objects directly. Each authoring tool loads different document types and associated data into SmartPlant Foundation to allow the exchange of data between the various authoring tools, avoiding the duplication of data for each tool.
