This question - how to create useful documentation for an ETL process - was one of the key aspects we worked to solve with the development of hale studio, our open source ETL framework. It helps the testing team to estimate testing effort needed, test coverage, resource tracking, execution progress, etc. Example ETLs. When the files are detected, they are converted, using the fallback JAXB Type Converter to a PersonDocument class. It is a complete suite of documents that allows you to describe and document test planning, test design, test execution, test results that are drawn from the testing activity. The sample ETL transformations document contains a number of example transformations, including identity handling and data-type mappings. Directory Structure. We use any of the ETL tools to cleanse the data. Convert Database to CDM (ETL) ETL creation best practices. ETL pipelines¶ This package makes extensive use of lazy evaluation and iterators.
