The ETL process is often used in data warehousing. [2] ETL systems commonly integrate data from multiple applications (systems), typically developed and supported by different vendors or hosted on separate computer hardware.
Power Query is an ETL tool created by Microsoft for data extraction, loading and transformation, and is used to retrieve data from sources, process it, and load them into one or more target systems. Power Query is available in several variations within the Microsoft Power Platform , and is used for business intelligence on fully or partially ...
A staging area, or landing zone, is an intermediate storage area used for data processing during the extract, transform and load (ETL) process. The data staging area sits between the data source(s) and the data target(s), which are often data warehouses, data marts, or other data repositories.
The data may pass through an operational data store and may require data cleansing for additional operations to ensure data quality before it is used in the data warehouse for reporting. The two main workflows for building a data warehouse system are extract, transform, load (ETL) and extract, load, transform (ELT).
An operational data store (ODS) is used for operational reporting and as a source of data for the enterprise data warehouse (EDW). It is a complementary element to an EDW in a decision support environment, and is used for operational reporting, controls, and decision making, as opposed to the EDW, which is used for tactical and strategic decision support.
Any number of readers, writers and transformers can be used in an FME workflow. A further tool is the Data Inspector, which can present spatial workflow results in a cartographic display. The ArcGIS Pro software can use the FME engine and workflows as part of the data interoperability extension. [11]
In a simplified CDC context, one computer system has data believed to have changed from a previous point in time, and a second computer system needs to take action based on that changed data. The former is the source, the latter is the target.
The extract, transform, load (ETL) step in populating data warehouses is inherently a batch process in most implementations. Performing bulk operations on digital images such as resizing, conversion, watermarking, or otherwise editing a group of image files. Converting computer files from one format to another.
