ECL is a remarkably powerful language for solving big data challenges — as you start learning the language, the ideas will begin to flow.
Our training options are sorted into learning tracks to make it easy to figure out what classes you should take in what order. First, select the learning track that best fits your needs. Once you have identified the courses you need, you can get started right away with our online classes or check the schedule and attend the next remote or in-person instructor led class.

Introduction to ECL (Part 1): Concepts and Queries
This class is for developers who want to understand HPCC Systems and learn ECL to build powerful data queries. Anyone who needs a basic familiarity with ECL should take this course.
Topics Include:
- HPCC Systems Overview (Thor and Roxie)
- Introduction to ECL Concepts and Syntax
- Using the ECL IDE and ECL Watch programming tools
- Flat and CSV File Sprays
- Defining Files (RECORD/DATASET)
- Record Filtering
- Basic Definition Types – Boolean, Value, Set, Recordset
- Creating Simple ECL Queries
- Managing your ECL Code
- Despraying Files
Introduction to ECL (Part 2): Data Profiling and Transformation
This intermediate level class is for developers who want to extend their knowledge of ECL to profile and transform any data with the HPCC Systems environment. Anyone planning to write and work with ECL code should attend this course.
Topics Include:
- Principles of ETL in ECL
- The TABLE Function (Memory Tables)
- TRANSFORM Functions (PROJECT, etc.)
- Data Hygiene (Cleaning and Standardization)
- Lookup Tables
- OUTPUT to Disk Files
- Simple JOINs
This course is the second in a two-part introductory series.
Advanced ECL (Part 1): Working with Relational Data
This class examines in detail the ECL functions that make it easy to work with relational data in the HPCC Systems platform. ECL began as an extremely powerful query language built around easily querying into relational data. The techniques taught here reveal that power to its fullest.
Topics Include:
- Creating Hierarchical Relational Datasets (Nested Child Datasets)
- Nested Child Dataset Definitions (RECORD/DATASET)
- NORMALIZE and DENORMALIZE
- Complex Multi-level Relational Querying
It is highly recommended that students take the Introduction to ECL (Part 1) – Concepts and Queries and Introduction to ECL (Part 2) – Data Profiling and Transformation training classes before starting this class.
Advanced ECL (Part 2): Super Files, Working with XML, Free-Form Text Parsing, and Machine Learning
This course explores the concept of Super Files in ECL and the techniques for working with XML data, getting it into your HPCC Systems cluster, and defining it to work with other data elements. This flows naturally into the detailed ECL support of Natural Language Parsing – creating pattern-matching definitions and using the PARSE function to extract data from either XML or free-form text.
Topics Include:
- SuperFiles and SuperKeys
- Simple XML Spray and Dataset Definition
- Working with XML Data (simple, complex, and nested)
- Complex XML Spraying and De-spraying
- PARSE with XML Data
- Spraying and defining free-form text data
- PARSE with free-form text
- New! An Introduction to Machine Learning
It is highly recommended that students take the Introduction to ECL (Part 1) – Concepts and Queries and Introduction to ECL (Part 2) – Data Profiling and Transformation training classes before starting this class.
Applied ECL: ECL Code Generation Tools
This class is for developers who want to extend their knowledge of ECL to use the ECL code generation tools to automate operational tasks.
Topics Include:
- Creating and using FUNCTIONMACROs
- Creating and using MACROs
- The ECL Template Language
- Automating ECL
- ECL Scheduling
It is highly recommended that students have completed the Advanced ECL (Part 1) – Working with Relational Data training course before starting this class.
ROXIE ECL (Part 1): Indexes and Queries
This class is for developers who want to extend their knowledge of ECL to developing ROXIE queries for end-user use. In this course you will learn the benefits of payload indexes, as well as use of the indexed joins that make query results fast. Anyone planning to write ECL code to provide final-product data to end-users should attend this course.
Topics Include:
- Defining and Creating INDEXes
- Using FETCH
- Creating ROXIE Queries (STORED)
- Testing Queries in Thor
- Deploying to ROXIE
- Payload Indexes
- Full and Half-Keyed JOINs
- Optimizing Queries (LIMIT, ATMOST, KEEP)
It is highly recommended that students take the Introduction to ECL (Part 1) – Concepts and Queries and Introduction to ECL (Part 2) – Data Profiling and Transformation training classes before starting this class.
ROXIE ECL (Part 2): Complex Query Development
Learn how to optimize and organize your ROXIE queries for optimal performance. This class reviews and recommends best practices used in ROXIE development, including INTERFACE, Half Keyed JOINS, LIMIT, superkeys, and package maps.
Topics Include:
- Using INTERFACE Structures with ROXIE Queries
- Limiting Your ROXIE Results (LIMIT, JOIN, CHOOSEN)
- Designing Queries Using Multiple Datasets
- Case Insensitive Searches
- Use of Superkeys in ROXIE Queries
- Use of Package Maps for Query Organization
- ROXIE-Specific Functions (PRELOAD, ALLNODES, etc.)
- ROXIE Post Filtering
To get the most benefit from this class, it is highly recommended that students take the Advanced ECL (Part 2) – Super files, Working with XML, and Free-form Text Parsing, and the Roxie ECL (Part 1) – Indexes and Queries training classes before starting this class.
Applied ECL: Special Projects
This class helps developers level up their skills from Student ECL Coder to Journeyman ECL Coder through a supervised real-world project.
Topics Include:
- One real-world project proposed by the student(s) and agreed to by the Instructor.
- Mentoring at every step, with guidance from project planning through completion.
- Regularly scheduled remote (Teams/Webex) meetings.
- Code Review
- Progress Evaluation
Class prerequisites: All other ECL Core Classes
