Building E6A, Room 102

Macquarie University

Keynote Speaker

Professor Philip Wadler, University of Edinburgh

A practical theory of language-integrated query
James Cheney, Sam Lindley, Philip Wadler

How best to blend a domain-specific language into a host language?
For the domain of databases, the old question of how to achieve
language integrated query is receiving renewed attention, in part
because of its support through Microsoft's LINQ framework. We present
a practical theory of language-integrated query based on quotation and
normalisation of quoted terms. Higher-order features prove useful
even for constructing first-order queries. We prove a theorem
characterising when a host query is guaranteed to generate a single
SQL query, and we present experimental results confirming our
technique works, even in situations where Microsoft's LINQ framework
either fails to produce an SQL query or, in one case, produces an
avalanche of SQL queries. Our ideas are implemented in F#, and the
talk briefly considers how they might apply to other languages such as
Scala and Haskell.

Local Arrangements

We have some funding from the Department of Computing at Macquarie University to support morning/afternoon tea. Attendees are responsible for their own lunch.

Directions

Please see these general directions for getting to Macquarie University campus. Campus maps can be found here. Building E6A is on the east side of campus about a five minute walk from the train station or shopping centre. Room 102 is a lecture room at the north end of E6A where building E6A joins building E6B.
