Method and System for Applying Changes to Elements in a Hierarchical Tree

Disclosed is a method and system for applying changes to elements in a hierarchical tree. Generally, changes are applied to elements in a hierarchical tree as a bottom-up rollup operation or as a top-down rollup operaion. However, the method and system disclosed herein uses a hybrid rollup approach to apply changes to elements in the hierarchical tree. The elements are classified into two categories, namely, container elements and leaf elements. Container elements are elements that have associated child elements in the hierarchical tree. Leaf elements are elements that do not have any associated child elements. For example, in the hierarchical tree structure illustrated in Fig. 1, program, project, iteration and summary are container elements and task is a leaf element.

For applying changes to the elements in the hierarchical tree structure, the method and system disclosed herein chooses a rollup container element. The rollup container element acts as a boundary while performing rollup. Accordingly, when elements are modified in the hierarchical tree structure, the changes are applied to the other elements in two phases as illustrated in the flow-diagram in Fig. 2. In the first phase, which is a bottom-up phase, the changed values of the modified element are rolled up till the rollup container element. In the...
