The final step in the ETL process is to load the newly transformed data into a new destination, for example, a cloud-based data warehouse like Google BigQuery, Snowflake, or Amazon Redshift.ĭata can be loaded to a data warehouse at once - full load or at scheduled intervals incremental load. It improves data integrity, removes duplicates, and standardizes the data so it arrives at its new destination fully compatible and ready to use. Transformation is probably the most important part of the ETL process. The data transformation process consists of several sub-processes like cleansing and deduplication, which we’ll cover in more detail below. In this stage of the ETL process, data is subjected to a matrix of rules and regulations that ensure data quality and accessibility. ETL tools now automate the entire process, giving way to more reliable data management. This stage was traditionally performed manually by data engineers and was time-intensive and prone to errors. Cloud, on-premises, and hybrid environments.Data sets can be extracted from a range of sources, including the following: In the first step of the ETL process, structured and unstructured data is consolidated into a single data repository. Extractionīefore data can be moved to a new destination, it must be extracted from various sources and data analysis tools.

If you’re looking to upgrade your data stack, switch vendors, or simply want to keep your business data safe in one place, book a demo call with our product manager and find out how Whatagraph can help.īut first, let’s explain how the ETL process works. Whatagraph not only saves the time needed to load data from multiple sources to Google BigQuery, but also allows you to generate beautiful interactive reports with only a few clicks. We simplified both processes to the point-and-click level so anyone can complete them. Provide effortless reporting on stored data.When designing Whatagraph, we wanted to achieve two things: The transformed data can also be used as a source for machine learning workflows or other data analytics uses. This can be a target database, data warehouse, data lake, or even multiple destinations.Ĭleaned data is often loaded into business intelligence (BI) tools for visualization and analysis by users who don’t need any tech skills. In a typical ETL workflow, data transformation is the stage that follows data extraction - a process where raw data is extracted from various data sources to the staging area.Īfter data is transformed, it is loaded into its data store. This includes cleaning the data, such as removing duplicates, filling in NULL values, and reshaping and computing new dimensions and metrics. The data transformation process is part of an ETL process (extract, transform, load) that prepares data for analysis.
