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