A model-driven approach for the development of native mobile applications focusing on the data layer

摘要

The data layer access design is a critical task for mobile applications which need constant access to remote data, making them available offline in case of network connectivity problems. Moreover, the variety of mobile operating systems and platforms (fragmentation phenomenon) that handles data storage differently affects the portability of mobile applications. This issue suggests the use of Model-Driven Development (MDD) approach that may ease the smartphone application development for different platforms. Therefore, we propose an extension of the Model-Oriented Web Approach (MoWebA) for the development of native mobile applications focusing on the data layer. MoWebA Mobile (as we name the proposal) covers data persistence concepts to achieve offline applications in case of network connectivity problems. It defines meta-models and the Architecture-Specific Model (ASM) for data persistence and data provider to design the data sources of mobile applications. As well, we propose transformation rules for the generation of Android and Windows Phone applications. The MoWebA Mobile process was illustrated by means of modeling, design, and development of a typical mobile application. Despite the learning curve of the approach, the first evaluation suggests that MoWebA Mobile has the potential for supporting the mobile design applications considering the persistence of data.
