You can import a physical layer residing in the Physical Metadata namespace This layer contains data source query subjects representing the imported tables. The physical layer contains query subjects and physical relationships between query subjects. These physical relationships are inferred from the relationships defined in the import file. Imported tables become Framework Manager query subjects, and surrogate keys become Framework Manager determinants. The regular dimensions may be conformed or non-conformed. The measure dimension objects correspond to the imported stars.

You can import A physical layer residing in the Physical Metadata namespace This layer contains data source query subjects representing the imported tables. The physical layer contains query subjects and physical relationships between query subjects. These physical relationships are inferred from the relationships defined in the import file. Imported tables become Framework Manager query subjects, and surrogate keys become Framework Manager determinants.

A dimensional layer residing in the Dimensions namespace This layer contains regular dimensions, measure dimensions, and scope relationships. The regular dimensions may be conformed or non-conformed.

The measure dimension objects correspond to the imported stars. The scope relationships are inferred from the relationships defined in the import file.

A logical layer residing in the Business View namespace This layer contains shortcuts to the regular and measure dimensions in the Dimension namespace. The shortcuts are organized as star schema groupings, which are namespaces with the same name as the stars from the import file. Facts A star maps to a Framework Manager query subject in the Physical Metadata namespace or as a measure dimension in the Dimensions namespace.

The following fact attributes are included in the model. Attribute name Framework Manager mapping Table name Name of the database query subject on which the model query representing the fact is based Short name.
