Unit 4: Use Case #1 – One-to-One Mapping

In this unit, we'll take a closer look at the first use case involving one-to-one mapping.

One-to-one mapping – resolving a challenge

As we dive deeper into examining our first use case of transcoding data using one-to-one mapping, we are presented with the following challenge as an example:

• Source dataset has the dimensions with ID "FREQ", "REF_AREA", and "INDICATOR"
• The REF_AREA dimension consists of 2-Letter ISO2 country codes
• Target dataset needs to have 3-letter ISO3 country codes

Select each option to learn about the solution to this challenge, along with specific values.

One-to-one mapping in action

Let's now consider an example of one-to-one mapping in action. In this short video, we'll examine creating the structures in FMR and then transcoding the datafiles using the UI and the API – sync & async.
