A computerized data processing system and method are provided. One embodiment of the system of the present invention includes a computer-readable memory for storing a definitional data table for defining variable symbols representing respective measurable physical phenomena. The definitional data table uniquely defines the variable symbols by relating them to respective data domains for the respective phenomena represented by the symbols. The system also includes a comparator for signaling existence of a match condition if both a symbolic description in an object instance describing at least one measured phenomenon matches one of the variable symbols in the table and an actual value, also in the object instance, of the at least one measured phenomenon conforms to a respective data domain defining the one variable symbol in the table. A object-to-relational data converter is provided for mapping the attributes of the object instance into two relational tables stored in the memory, an observation table and a measured value table, if the match condition is signaled by the comparator. The converter maps the symbolic description from the object instance into the observation table in association with a unique identification number for the object instance, and also maps the respective data domain and the actual value into the measured value table in association with the unique identification number. Particular utility for the present invention is found in processing, storing, and retrieving of heath-care related in and from, respectively, very large database systems, although other utilities are also contemplated for the present invention.
