Data mapping

Data mapping is like drawing a map. When you’re drawing a map, you need to draw lines from one place to another to show how they’re connected. Data mapping is the same way but instead of drawing lines between places on a map, you draw lines between pieces of data in your computer. Data mapping helps computers understand how they should organize information. For example, if you wanted to store all the people in your family in a database, data mapping would help the computer know where to store everyone’s name, age, address, and other information.
