In some example embodiments, a system is provided for executing a primitive call that implements a query operation. The system may include a data processor and a memory. The memory may store instructions that result in operations when executed by the data processor. The operations may include: executing, at an data management engine, the primitive call by at least performing a first operation with respect to a value identifier set, the value identifier set including one or more value identifiers, and the primitive call being configured to access a database storing a plurality of value identifiers; and generating, based at least on a result of the first operation, a result for the primitive call. Related methods and articles of manufacture, including computer program products, are also described.
