Object-relationship modelling

Object-relationship modeling is like playing with dolls, but instead of dolls, we use words to understand how things are connected.

Okay, so let's say we have a doll named "Lisa" and a car named "Ferrari." We know that Lisa can drive the Ferrari, but how do we show that on paper so that other people can understand it too?

This is where object-relationship modeling comes in. We draw pictures and write down words to show how Lisa and Ferrari are related. We draw a line from Lisa to Ferrari and write "drives" next to it. This means that Lisa can drive Ferrari. We can also draw another line from Ferrari to Lisa and write "owned by" next to it. This means that Ferrari belongs to Lisa.

Object-relationship modeling is like a puzzle. We have to figure out how things are connected, and then draw a picture and write down words to explain it. This helps us understand how things work together and makes it easier for others to understand it too. So, next time you play with dolls or play with toys, you can practice object-relationship modeling to understand how everything fits together!
