VTL Training

This repository contains training materials for VTL 2.1.

Notes

VTL does not define how to load/persist data.

In the VTL scripts provided in this repository, we use the following notations to represent data import and export:

import: foo.bar, in an expression, means you read the bar data source located in foo(path/method defined elsewhere, according to the tool)
export: baz.quux in a persistent assignment, means you will persist the quux dataset in baz (path/method defined elsewhere, according to the tool)

Example:

baz.quux <- foo.bar [keep aa][rename aa to bb];
