The Topology Builder is a tool used to create and add business elements to the business-related topology loaded into the Global Manager’s repository from the Business Impact Manager’s import datafiles. Typically, you use the import datafiles to create most of the business elements, and use the Topology Builder to create smaller collections of business elements.
You use the Topology Builder to create business elements, to create relationships (links) between business elements, and to create relationships between business elements and infrastructure, application, or hierarchical group elements. The analysis performed by a Manager such as Business Impact Manager depends on the relationships between topology elements.
