Edit the contents of a package by including or excluding model objects such as namespaces,
folders, and query subjects.

B.
Publish packages to the network as well as to the content store in order to maintain model
versioning and prevent report errors.

C.
Perform an impact analysis on a package to identify the impact of changing the cardinality of a
relationship between two query subjects included in the package.

When publishing packages, use file system version control so that reports created based on

many times the package is published.
