ECL Programmers Guide

The ECL Programmers Guide gives an introduction to the ECL language along with example data and use cases.

ECL Language Reference

ECL is the Enterprise Control Language designed specifically for huge data projects using the HPCC platform. Its extreme scalability comes from a design that allows you to leverage every query you create for re-use in subsequent queries as needed. To do this, ECL takes a dictionary approach to building queries wherein each ECL definition defines an Attribute. Each previously defined Attribute can then be used in succeeding ECL Attribute definitions as the language extends itself as you use it.

Visualizing ECL Results

The ECL compiler now supports adding external resources to a Workunit using a manifest file. The manifest, in XML format, adds external resources such as XSLT transformations, or other objects to the archive before it is compiled and deployed to the server. This document demonstrates how to use this feature to visualize ECL job results using Google Chart Tools.
