     5 Queries are extremely important in software development and having a
     6 robust query engine is a must for CC.
     7 
     8 Our goal is to develop a query-language compiler (Q) which can be
     9 tuned at compile-time to meet the needs of any database backend.
    10 
    11 The query languages that interest us most are derived from Prolog
    12 (/datalog) and SQL, but we won't be supporting all of their features -
    13 only the ones that can be reasonably coerced to all supported frontends.
    14 
    15 Q will require an Intermediate Representation (IR) - the encoding will
    16 be based on S-expressions with a specialized reader.
