An organization want to develop an application programming interface (API) to seamlessly exchange personal data with an application hosted by a third-party service provider. What should be the FIRST step when developing an application link?

Show Suggested Answer Hide 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.

Wait, isn't data tagging the first thing we should do?

I practiced a similar question, and I think data mapping was emphasized as the initial step to ensure everything aligns correctly.

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

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