K2 [13] is a distributed query system that has been developed at the University of Pennsylvania. K2 relies on a set of data drivers, each of which handles the low-level details of communicating with a single class of underlying data sources (e.g., Sybase relational databases, Perl/shell scripts, the BLAST family of similarity search programs, etc.). A data driver accepts queries expressed in the query language of its underlying data source. It transmits each such query to the source for evaluation and then converts the query result into K2 s internal complex value representation. Data drivers are also responsible for providing K2 with data source metadata (i.e., types and schemas), which are used to type check queries.
