VIRTUAL FOLDERING SYSTEM FOR BLENDING PROCESS AND CONTENT IN A COLLABORATIVE ENVIRONMENT

A computer system that includes a processor and a storage medium. The storage medium stores a database of tables and a calculation engine. Each table includes columns and rows. The tables describe components of a hierarchy in which hierarchical relationships between components of the hierarchy are defined. The tables include a component table and component-specific tables. The components of the hierarchy encompass component types. Each component-specific table encompasses only components of the hierarchy. The calculation engine includes a popup calculator being displayed to a user via a display interface of the computer system upon the calculation engine being executed by the processor. The popup calculator performs, under interactive control by the user via the display interface, an evaluation of a specified function of set of functions and displays a result of the evaluation to the user via the display interface.
