The Development of Core Logic for an Estimate System Using the Cellular Data System

In the era of cloud computing, data is processed in "Cloud", and data and its dependencies between systems or functions progress and change constantly within the cloud, as auser\´s requirements change. Such information worlds are called cyber worlds. We need a more powerful mathematical background which can model the cyber worlds in the "cloud"as they are. We consider the Incrementally Modular Abstraction Hierarchy (IMAH) to be appropriate for modeling the dynamically changing cyber worlds by descending from the most abstract homotopy level to the most specific view level, while preserving invariants. We have developed a data processing system called the Cellular Data System (CDS) based on IMAH. In this paper, we introduce into CDS the applied functions for calculating numerical values, and apply CDS to develop the core logic of an estimate system, used in most industries but costly due to its complexity, to verify its effectiveness.
