Representation of ETL Workflow ETL in Cloud When handling huge volumes of data and many source systems, the data is combined into a single data store.ĮTL is used to transfer data from an existing database to another database, This is the only process involved in loading the data to and from data warehouses and data marts. The data from multiple sources is extracted and this data is further copied to the existing data warehouse. The load is the final step of the ETL process which writes the data into the target database.The various methods used for transforming the data are filtering, sorting, conversion, removing the duplicates, and translating. Transform converts the extracted data from its initial format to the required format.There are many storage systems where the data can be stored, some of them are XML files, Flat files, Relational Database management systems(RDBMS), etc. Extract involves the process of reading the data from a particular database which is collected from multiple sources.This data is used for storing in a database and used for future reference. It extracts the data from different sources and converts it into an understandable format.
