Data truncation

Data truncation is like trying to fit a big toy into a small toy box. Imagine you have a toy car that is too big for your toy box. You want to put it in the box, but it just won't fit because the box is too small.

Similarly, data truncation in computer terms, is when you have too much information (big toy car) and you have to put it into a small storage space (toy box). But, there is a problem because the storage space is not big enough to fit all of the information.

When this happens, the computer has to choose what information to keep and what information to leave out. So like with the toy box, the computer will have to cut off the extra part of the information that won't fit in the storage space.

This can be a problem because the information that gets cut off might be important and not having all of the information could cause errors in whatever the computer is doing. So it's important to make sure the storage space is big enough to fit all the information or find a different way to store the information that won't cause data truncation.
