CImplement different system APIs named createCustomerInCRMZ, amendCustomerInCRMZ, retrieveCustomerFromCRMZ and suspendCustomerInCRMZ as they are modular and has seperation of concerns

Show Suggested Answer

Suggested Answer: B

Correct Answer : Implement different system APIs named createCustomer, amendCustomer, retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns

*****************************************

>> It is quite normal to have a single API and different Verb + Resource combinations. However, this fits well for an Experience API or a Process API but not a best architecture style for System APIs. So, option with just one customerManagement API is not the best choice here.

>> The option with APIs in createCustomerInCRMZ format is next close choice w.r.t modularization and less maintenance but the naming of APIs is directly coupled with the legacy system. A better foreseen approach would be to name your APIs by abstracting the backend system names as it allows seamless replacement/migration of any backend system anytime. So, this is not the correct choice too.

>> createCustomer, amendCustomer, retrieveCustomer and suspendCustomer is the right approach and is the best fit compared to other options as they are both modular and same time got the names decoupled from backend system and it has covered all requirements a System API needs.

I'm with the others on this one. Option C is the clear winner. Though I do wonder if the CRM-Z developers are still using floppy disks and punch cards...

Option B looks good too, but I think C is the stronger choice. Who wants to deal with a generic 'customerManagement' API when you can have specific, descriptive ones?

I agree with My. Option C is the most modular and maintainable approach. Separating the concerns like that is a best practice.

I think option A is the best choice because having all functionalities in one API makes it easier to manage.
