1.71 MonetDB Version 5
The MonetDB product family consists of a large number of components developed within our group over the last decade. Some components have already been shipped to happy customers, some are still in the making, and others have found a resting place in the attic.
The MonetDB architecture is designed to accommodate a wide-spectrum of standardized query language front-ends (SQL, XQuery), a variety of query transformation schemes, and different execution platforms (interpreted materialized or pipelined, dynamic compilation).
MonetDB Version 5 is a major release of our software infrastructure. The most notable differences are its greatly improved software stack and a new interface language, which turns the database server back-end into an abstract database machine with its associated assembly language (MAL). It supports backward compatibility of interfaces, tools, and source sharing where feasible within the limited scope of resources available.
In the remainder of this section we shortly introduce the MonetDB Version 5 design considerations and a quick overview of its architecture.
