Introduction
The
query-compiler package is a set of tools for the inspection of the process of query compilation. It shows how a SQL query is parsed, desugared, translated in relational algebra and optimized. The user interface is web-based, implemented using
stratego-net and
xml-tools?. Of course the components of the query-compiler are also available as command-line utils.
The
query-compiler is based on the
sql-front and
relational-algebra packages.
sql-front is used to parse a SQL query to an abstract syntax for SQL. The relatonal-algebra packages implements the optimization of relational algebra and the renderering of relational algebra expressions in
MathML?.
