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.
