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.
