Remote Training: 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.
