online etl testing training



ETL process involves extracting the data from the sourcesystem(s). In many cases, this represents the most important aspect of ETL,since extracting data correctly sets the stage for the success of subsequentprocesses. Most data-warehousing projects combine data from different sourcesystems. Each separate system may also use a different data organization and/orformat. Common data-source formats include relational databases, XML, JSON andflat files, but may also include non-relational database structures such asInformation Management System (IMS) or other data structures such as VirtualStorage Access Method (VSAM) or Indexed Sequential Access Method (ISAM), oreven formats fetched from outside sources by means such as web spidering orscreen-scraping. The streaming of the extracted data source and loadingon-the-fly to the destination database is another way of performing ETL when nointermediate data storage is required. In general, the extraction phase aims toconvert the data into a single format appropriate for transformationprocessing.
