The cleaned-up data is then converted from a database format to a warehouse format. Once stored in the warehouse, the data goes through sorting, consolidating, and summarizing, so that it will be easier to use. Over time, more data is added to the warehouse as the various data sources a...
ETL is a data integration process that extracts, transforms and loads data from multiple sources into a data warehouse or other unified data repository.
In contrast, with ELTs, the staging area is in the data warehouse, and the database engine that powers the DBMS does the transformations, as opposed to an ETL tool. Therefore, one of the immediate consequences of ELTs is that you lose the data preparation and cleansing functions that ETL...

The ETL process refers to the movement of data from its raw format to its final cleaned format ready for analytics in three basic steps (E-T-L): Extract. Data is extracted from its raw data sources. Transform. Data is transformed (cleaned, aggregated, etc.) to reshape it into a usable...
Staging areas are used for both ELT and ETL, but with ETL the staging areas are built into the ETL tool being used. With ELT, the staging area is in a database used for the data warehouse. A visual of how ELT and ETL process data differently ...

Data ingestion is the process of obtaining and importing data for immediate use or storage in adatabase. To ingest something is to take something in or absorb something. Data can be streamed in real time or ingested inbatches. In real-time data ingestion, each data item is imported as the...
