Data Mapping the Vault

Course overview

About this course

There is a vault. To open it, you need a four-digit code — and the only way to find it is to master data mapping. Learn how data flows between systems, screens, and APIs, then prove it across four parts of increasing difficulty. The final challenge will test everything: reading an API response, using a mapping file, and applying a query to find the code hidden in the results.

What you'll learn

Practical outcomes

  • What data mapping is and why it matters when systems exchange information.
  • How to read and write dot notation, including array indexing.
  • How to trace a value on a screen back to its source field in an API response.
  • How to map fields between two APIs, including when one field must be split across several.
  • How to apply filtering, sorting, and pagination to work out what data is actually displayed.

Pre-requisites

What you should know first

  • No coding experience required — all concepts are taught from the basics.
  • Helpful: comfort reading structured information like tables or forms.
