The market players are struggling to adapt their business processes to the mobile world. There are thousands of mobile applications in stores, already developed and published.
The world of enterprise applications is undergoing a revolution as the smartphone becomes employees' go-to information appliance. Smartphones now are able to replace traditional PCs, Notebooks and other everyday facilities; moreover, involving smartphones gives mobility and more flexibility.
As mobile technologies are getting popular, mobile application development approaches become better, in order to produce simple, usable, powerful and beautiful applications. Rapidly growing requirements to the functionality, design and usability of applications force developers to find out new efficient ways in programming.
One of such approaches is mobile backend cloud services. There are two reasons of why these services are getting widely used as nowadays modern programming techniques:
- Huge inconvenience in developing and updating offline mobile application with local database. After every, even little, software update there is a necessity to publish application again. It takes a plenty amount of time and resources. Also, users have to update their mobile apps, after it is republished at mobile application stores;
- Rapid penetration of mobile internet in cities. This gives an opportunity to develop online applications, where changes to mobile apps data are able to be done once user connected to the internet. There is no necessity to republish the app in stores, because all changes and data are synchronized between a server and app.
There are few mobile backend services such as Parse, SAP, Kinvey or BAASBOX which gives availability to developers to create mobile applications with online data synchronization.
But now, already, thousands of offline mobile application have been developed and used among users. What to do with them?
The research of mine is dedicated on creating and implementing a methodology by which, developers would be able to change their application from offline mode apps to online once. This will allow to thousands of applications to change the traditional workflow to modern and demanded one.
The practical implementation is done on existing mobile application named “KazLearn”. “KazLearn” is a mobile application which allows learning Kazakh language for beginners by taking simple lessons. The problem with this application is that there is no availability to update the list of the lessons online. Every lesson update or even a small change is followed by republication of app in Google Play store.
So, to avoid this, mobile backend server has been created all of the existing content transferred to the server. The data synchronization is done through HTTP Application Programming Interface. Following is the resulting sequence diagram, which shows the implementation:
So now, once the application started, it begins the synchronization process. This guarantees that the data always up to date. From the other side, it becomes simpler to make changes, because it is done on the server side. All the updates take place simultaneously.
