Language-integrated queries: a BOLDR approach
Intervenant(s) : Julien LOPEZ (LRI - université Paris sud)
We present BOLDR, a modular framework that enables the evalu-
ation in databases of queries containing application logic and, in
particular, user-defined functions. BOLDR also allows the nesting
of queries for different databases of possibly different data models.
The framework detects the boundaries of queries present in an
application, translates them into an intermediate representation
together with the relevant language environment, rewrites them in
order to avoid query avalanches and to make the most out of data-
base optimizations, and converts the results back to the application.
Our experiments show that the techniques we implemented are ap-
plicable to real-world database applications, successfully handling
a variety of language-integrated queries with good performances.
