This interaction is expected to make your information an analyzable entirety. It comprises three stages, Extract, Transform, and Load.
ETL programming used to be hand-coded, however, today it very well may be smarter to utilize an upgraded ETL device. ETL tools are a class of specific tools or devices with the errand of managing data warehouse homogeneity, cleaning, transforming, and loading issues. An ETL tool can give the business various advantages.
We’ll go inside and out with the ways an improved ETL process can benefit your business.
