    With all your data in one place, it becomes simpler to perform analysis and reporting at different aggregate levels..

  • What is loading?

    Initial Load: For the very first time loading all the data warehouse tables.Incremental Load: Periodically applying ongoing changes as per the requirement. Full Refresh: Deleting the contents of a table and reloading it with fresh data.
Data loading (the “L” in “ETL” or “ELT”) is the process of packing up your data and moving it to a designated data warehouse. At the beginning of this transitory phase, you can plan a roadmap, outline where you would like to move forward with your data, and consider how you would like to use it.
Data loading is quite simply the process of packing up your data and moving it to a designated data warehouse. It is at the beginning of this transitory phase where you can begin planning a roadmap, outlining where you would like to move forward with your data and how you would like to use it.
In the process of Data Loading the data is physically moved to the data warehouse. The Data Loading takes place within a “load window. The tendency is close to real-time updates for data warehouses as warehouses are growing used for operational applications. Cloud-based.

Transform

In the staging area, the raw data undergoes data processing. Here, the data is transformed and consolidated for its intended analytical use case

Load

In this last step, the transformed data is moved from the staging area into a target data warehouse. Typically
