Abstract: A cellular model based on the Incrementally ModularAbstraction Hierarchy (IMAH) is a novel model that can represent thearchitecture of and changes in cyberworlds, preserving invariants froma general level to a specific one. We have developed a data processingsystem called the Cellular Data System (CDS). In the development ofbusiness applications, you can prevent combinatorial explosion in theprocess of business design and testing by using CDS. In this paper, wehave first designed and implemented wide-use algebra on thepresentation level. Next, we have developed and verified theeffectiveness of two general business applications using CDS: 1) acustomer information management system, and 2) an estimate system.
