Data cleansing

Have you ever played with your toys and made a mess in your room? You know how your parents ask you to tidy up your room and put everything in the right place? Well, it's a bit like that with data cleansing.

Data cleansing is like cleaning up a big mess of information. Just like you have to organize and tidy up your room, companies and organizations have to keep their information clean and organized too. But instead of toys, they have lots and lots of numbers, letters, and symbols that make up their data.

Sometimes, when people use computers to collect information, they might make mistakes - like spelling a name wrong, putting in the wrong number, or even adding extra information that is not needed. These mistakes can cause problems when you want to use the data later.

So, data cleansing helps to make sure that there are no mistakes in the big mess of information. It's like a special type of cleaning that makes sure that all the pieces of information are in the right place, and that there are no mistakes or extra bits that don't belong there.

By doing this cleaning process, companies can make sure that their information is accurate, and they can use it to make important decisions. It's like having a clean room, where you can find everything you need, and you can play without worrying about stepping on something that could hurt you.
