We harvest links to their datasets on a weekly basis. Extract In this phase, raw data is extracted from multiple sources and stored in a single repository. We did not want to impose a separate publishing process for each of these organizations, and were able to instead set up a workflow where they publish to their own repository. We also harvest the geographic data catalog from Allegheny County and the City of Pittsburgh‘s ArcGIS Open Data Portals on a weekly basis. The publishing frequency for each dataset is available in the metadata record for each dataset. Using “_etl” as a search term on the open data portal will provide you with a current list of datasets that are published through an automated process. We have added “_etl” as a tag to each of the datasets we automated through our own internal processes. The framework for automating a publishing process is commonly referred to as “Extract – Transform – Load” (ETL). We work closely with our publishers to automate their publishing processes, and have developed an automated publishing toolkit to make our processes more efficient. People get busy, go on vacations, and switch jobs, so taking the human element out of the process can result in a more predictable and efficient publishing workflow. Pass data between your specialized processes to aid in de-coupling. By identifying and preventing data quality issues such as duplicate data or data loss, ETL testing saves you. It’s a crucial component of data warehouse testing. According to Forbes, 95 of businesses need new means. ETL testing is the process of verifying that the data from source systems has been extracted completely, transferred properly, and loaded into the new system in the correct format. But in order to effectively analyze data from multiple sources, you need to properly aggregate, clean, and store it. Analyzing your data is one of the best ways to evaluate performance and make better business decisions. We learned early-on about the importance of automating the data publishing process.
