Introduction
In this project. On this project, I was advised to work as a trainee data
analyst for a new firm. Primarily, I want to develop a helpful spreadsheet
model that can predict how changes in exchange rates would affect a
company's profit margin. Using this information, I will design a data model
that meets all the client's criteria, including worksheet structural diagrams
and a test plan. The design would next be discussed with other clients to
identify and propose adjustments. I will also describe how the criteria are
fully addressed, and then I will analyze the optimized data model while
considering current customer requirements.

Scenario
P3
Data modelling is the process of simulating a real-world scenario in which
business choices must be made using a spreadsheet or similar tool. The
data model may be used to gather data, and a number of software
applications can be used to make the data understandable, accessible, and
easy to use. To aid in assessing various possibilities, data modelling is used.
You will learn how to evaluate models and provide evidence for your
decisions.
