products using an open-ended, variable set of query criteria. The resulting queries can have
widely different structures and use a number of aggregate functions. The actual querying is

by the company. The company values ease of development and does not want to see resources
taken away from the company’s main specialty, which is financial analysis. Which persistence
technology best supports this company’s requirements?
