Advanced ECL - Working with Relational Data
This class examines in detail the ECL functions that make it easy to work with Relational data in the HPCC system. 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.
Course Length: 2 days
Class Prerequisites: Students must have attended the Introduction to ECL and Introduction to Thor Training classes. Students are welcome to bring their own laptops to take away the code and examples from the class.
- Creating hierarchical relational datasets (Nested Child Datasets)
- Nested Child Dataset Definitions (RECORD/DATASET)
- NORMALIZE and DENORMALIZE
- Complex Multi-level Relational Querying
Note: We recommend that people who attend the Advanced ECL class also attend the Advanced THOR class if it meets your schedule, as they are both presented in the same week.
