Queries are extremely important in software development and having a |
|

|
robust query engine is a must for CC. |

Our goal is to develop a query-language compiler (Q) which can be |
|

|
tuned at compile-time to meet the needs of any database backend. |

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. |

Q will require an Intermediate Representation (IR) - the encoding will |
|

|
be based on S-expressions with a specialized reader. |
