Cyberworlds are distributed systems where data and their dependencies are constantly changing and evolving. In such business application systems, combinatorial explosion happens because schemas and application programs must be modified whenever schemas change, if existing techniques are used. To solve the problem, we have developed a data processing system called Cellular Data System. In this paper, we design and implement a condition formula and its processing maps as an important function in CDS. A condition formula processing is a very effective measure when a user wants to analyze data in cyberworlds without losing consistency in the entire system, since he/she can search for the data you want without changing application programs, if he/she employs a condition formula processing.
