Answer:
In computing, extract, transform, load (ETL) is the general procedure of copying data from one or more sources into a destination system which represents the data differently from the source(s) or in a different context than the source(s).
Data extraction involves extracting data from homogeneous or heterogeneous sources; data transformation processes data by data cleansing and transforming them into a proper storage format/structure for the purposes of querying and analysis; finally, data loading describes the insertion of data into the final target database such as an operational data store, a data mart, data lake or a data warehouse.

<em>GUI provides simple and easy way to operate computers. </em>
<u>Explanation:</u>
Before <em>GUI there were only CUI (Character User Interface) where the user needs to remember lots of commands to interact with computer </em>and it is also time consuming.
<em>Eg. DOS (Disk Based Operating System). </em>
This problem was overcome by GUI where it contains buttons where the user can use the <em>mouse to click, double click or right click </em>according to the options provided by the environment. <em>GUI is the successor of CUI.</em>
