Renaming Objects in the Business Layer
The next time you need to do any renaming of your business layer of the repository, try using the Rename Wizard, located under Tools > Utilities. This will allow you to quickly and globally replace underscores with spaces, database names with business names, change from all caps to first letter capitalized only, and perform many other useful Find and Replace operations. The Wizard allows you to create an ordered sequence of operations, and to which repository objects to include in the processing. Be aware though, if you include objects from the presentation layer, the original object names will be preserved as aliases once you have renamed them using the Wizard.
Hiding Layers in the Administration Tool for Ease of Use
Under the View menu, consider displaying only the repository layers that you are working on. Your eyes will thank you! Viewing all three repository layers at once reduces visibility to objects with long names, especially in the logical layer.
