This is an old post but I think it’s still relevant.
The Bring Your Own Device (BYOD) movement has gained unstoppable momentum. And thanks to the burgeoning mobile app market, employees have high expectations for these tools. They want an attractive user experience tailored to their devices. In other words, companies need to invest in building apps, period.
During the internet explosion, applications settled on three tiers: presentation, logic and data. [..] the lines between the presentation and logic tiers frequently blurred, and a hard border was created between the logic and data tiers.
However, I believe that the overwhelming emphasis on user experience combined with the impact of cloud and big data will now blur the line between logic and data, and the border between presentation and logic will become much more complete. That concrete border has a name: it is the API. That order process now needs to be available on the web and to a variety of mobile devices, so that the logic tier can be accessible to all channels through the API.
