Show Suggested Answer

Suggested Answer: C

Data mapping is the process of defining how data elements from different sources are related, transformed, and transferred to a common destination. Data mapping is the first step when developing an application link because it helps to ensure that the data exchanged between the API and the third-party application is consistent, accurate, and compatible. Data mapping also helps to identify any gaps, errors, or conflicts in the data and resolve them before the data transfer occurs.

I feel like data tagging might be relevant, but it seems more like a later step in the process.

I'm not entirely sure, but I remember something about data normalization being important for ensuring consistency.

I think the first step should be data mapping since it helps in understanding how the data will be structured between the two systems.
