ELI5: Explain Like I'm 5

Dimensional modeling

Okay kiddo, so let me explain dimensional modeling to you in a way that is easy to understand.

Have you ever played with building blocks? Blocks can come in different shapes and colors like circles, squares, and triangles. It's fun to put them all together and make a big structure!

Now, imagine that you have data instead of blocks. Data can be like information about customers, sales, or products. In dimensional modeling, we take this data and organize it in a way that makes it easy to understand and use.

We start by creating a simple shape, like a rectangle or cube, called a "fact table." This table contains all of the important data that we want to analyze. For example, a fact table for a toy store might contain information about each product sold, such as the price, quantity, and date of sale.

Next, we add more shapes, called "dimension tables," around the fact table. These tables contain information about the different factors that might affect the sales of toys, like the store location or time of year. Each dimension table has a unique key that we use to link it to the fact table.

Just like how you can use building blocks to make different structures, we can use dimensional modeling to make different kinds of reports and analyses for business use. This is how we can easily understand and make decisions based on lots of data!
