Getting Started

This page describes how to get started with the open-source CQL IDE.

The suggested introductory course of study includes an introductory paper about CQL for computer scientists, introductory slides and video about CQL from a functional programming perspective, introductory slides and video about CQL from a mathematical perspective, introductory slides about category theory from a knowledge management perspective, a paper from NIST arguing that category theory is critical for IT interoperability, and an introductory textbook on category theory, as well as a data science case study.

See the CQL Wiki for links to JDBC drivers, known limitations, etc, and the CQL Manual for a description of CQL's syntax and an index of the IDE's built-in examples. Once downloaded, double click cql.jar to open, or run java -jar cql.jar at the command line. To get started with CQL once it is running, see the examples below.
