Want to show room availability

Need to find a robust way for mobile client to retrieve data; definitely not DB connection How to authenticate the mobile client There are multiple room booking systems on campus

API Platform A robust way to retrieve data

Authentication API platform

Process API for aggregating all booking systems data System API for Booking System A Consumed by System Booking API for Booking System B

System API of Booking System B System API of Booking System C We need to cache the result Process API for aggregating the data from all booking systems

Finally … • The City. U mobile app with room availability function was launched • as a strategic project of Office of CIO and; • as the first user of the API platform • The cache shortens the room availability search time from 3 seconds (the patient limit of a human being) down to less than 0. 5 second

MVC framework Loose coupling between APIs System API Decouple the details of the data model Message-driven Process API Define the business logic and orchestrate the processes Experience API Transform the data for UI component’s consumption

Did the one who built the base station know that “someone” would use it? What if the designer changes the base station design? Would it break the bird nest?

Did the programmer who built a function know that “someone” would use it? What if the programmer changes the function design? Would it break other one’s program?

Looking Forward …

Recap • API architecture design is important • MVC framework • API registration and interdependency map is important • Reduce the risk of broken code • Enable cross ERPs workflow in a more robust and real-time way

Thank you
