Data objects stored in a data store include data attribute(s) and associated value(s) for the attributes. Data analysis tools (DATs) stored in a data store are associated with reference data attritbute(s). The data objects are identified by one or more DATs based on each reference data attribute(s) of a corresponding DAT matching one of the data attribute(s) of the corresponding data object(s) and independent of the value for the data attribute(s). The DATs generate an additional data object as a function of the identified data object, and the additional data object is stored in the data store.
