In the previous step, you had to complete an assessment to test your knowledge on all that we’ve learned thus far. In this step, we explore the fundamentals of Data Modelling.

When we plan and create solutions to implement business requirements, we need to be able to describe, model the objects and the data we’re going to be dealing with. This is where data modelling comes in.

As Wikipedia defines it, ‘Data modelling is a process used to define and analyse data requirements needed to support the business processes within the scope of corresponding information systems in organisations.’

The outcome of the process is a data model that is an organised, structured representation of the business requirements in the form of entities with fields, and relationships that connect them.

In this video, Julie Yak provides an overview of Data Modelling.

When we plan and create solutions to implement business requirements, we need to be able to describe, model the objects and the data we’re going to be dealing with. Can you think of real-life examples of entities where we store/capture/manage data?
