As an aspiring BA, I have been researching the internet for practical examples of a requirement that has been translated into a functional requirement. Unfortunately, my internet queries yield theory, which is great, however, I am seeking examples. Below I have created a fictitious requirement and I would like to understand how to convert this into a technical requirement.

“The user shall be able to search either all of the initial set of databases or select a subset from it”

How would this be written to enable developers to develop the code? Or will the developers utilize the use cases and UML diagrams?

Thanks

I have visited a number of these websites previously. Thanks for the response
