摘要: A method and a system for evaluating data. The method comprises: receiving an Object Constraint Language (OCL) expression-based evaluation request; transforming at least part of the OCL expressions in the evaluation request into query requests; querying relevant data based on the query requests; and evaluating data obtained from the querying based on the evaluation request. The present invention may support evaluation of complex OCL expressions on a mass data set.
