Analysis and Design Methodologies for Future Mobile Services Essay in DT 8100 , Spring 2005

A lot of technologies that together can be used to realize truly mobile services have emerged lately; different handheld devices with various functionalities and form factors, broadband connections and wireless access networks are ubiquitously available both at home, at enterprise locations and elsewhere at public locations. However, it is not straightforward to design highly available software systems and services even if the underlying technology is in place. Careful analysis of requirements, posed by a range of different actors, and adequate middleware and service designs are needed to exploit these technologies optimally. Software engineering methodologies have also changed a lot the last 30 years, from the procedural-oriented, through object-oriented and component-based. Nowadays, service-oriented computing and architectures are emerging as promising concepts for the description of, publication of and interaction with services realized by highly distributed systems. This essay couples the advances in mobile technology with the advances of software engineering methodologies and concepts, to see how these can support several phases of the development cycle of future, data-based mobile services.
