A system, apparatus, method, and computer-readable media are provided for efficient database lookup operations. According to method, procedural checks for generating a response to a database query are converted into a set of database operations. The database operations are performed the first time a query of the database is received to generate a set of possible results for the query. The set of possible results for the query are then stored. A specific answer to the query is generated from the set of possible results. Future database queries are responded to by generating an answer to the query from the stored set of possible results.
