TAILIEUCHUNG - SAS/Warehouse Administrator 2.3 Metadata API- P13

SAS/Warehouse Administrator Metadata API- P13: The operating system and SAS version that are associated with a given host are now available through the WHHOST property. For example, you can write a SAS/Warehouse Administrator add-in that reads the host metadata that is associated with a given data store and then uses these values to generate code that is appropriate for the operating system and SAS version. | SAS Warehouse Administrator Metadata Types A Relationships Among Metadata Types 57 Note that there can be zero or more WHTBLPRC type objects between two WHTABLE subtype objects. The previous figure shows one intermediate WHTBLPRC object. This diagram shows the overall process flow as well as any relationships that might be specific to the WHPRCMAN type objects. Note that for simplicity the relationships have been drawn for only one of the WHPRCMAN type objects in the diagram but these relationships exist for all WHPRCMAN type objects. Physical Storage Metadata Type Models Physical storage information is different for SAS data stores type WHSASSTR and DBMS data stores type WHDBMSST . The following figure shows how to access a common set of metadata for a SAS data store. Figure SAS Data Store Metadata Type Model The following figure shows how to access a common set of metadata for a DBMS data store. Figure DBMS Data Store Metadata Type Model 58 Relationships Among Metadata Types A Chapter 3 OLAP Metadata Type Model The following figure shows how to access metadata that defines the structure of an OLAP table Group or MDDB in SAS Warehouse Administrator including OLAP cubes crossings dimensions hierarchies and columns. Figure OLAP Metadata Type Model Column Mapping Types ODD to Detail Table Model The following figure shows how to access the metadata that defines the column mappings between an operational data definition ODD and a detail table. Figure Mapping Model ODD to Detail Table The ODD type WHODDTBL and detail table type WHDETAIL inherit the metadata that is shown in Figure on page 55. Note If the logic that is needed to transform the operational data column into the detail data column is not important for your application then you can use the output objects input objects relationship. For details see INPUT and OUTPUT Properties on page 64. a SAS Warehouse Administrator Metadata Types A Writing Metadata 59 Note There can be zero or more .
