Mobile phones are becoming a new popular platform for business applications. The number of mobile users increases daily and so does the need for efficient mobile data access and management. However, a traditional approach to business application and database design is not suitable for mobile devices because of the limited memory and connection bandwidth. This paper presents a novel lightweight mobile SOA-based architecture for business applications running on J2ME enabled devices such as cell phones. The paper includes position statement based on our experience and describes a first prototype implementation of the architecture. Some important features of our design are: using the knowledge of business processes to minimize data transferred to and stored on the device; pro-active data loading; allowing applications to fully function in a disconnected mode. The above architecture results in a lightweight framework, which can be used in order to develop a wide spectrum of business-oriented mobile applications. [ABSTRACT FROM AUTHOR]

One of the challenges for information system architects and interface designers is organizing the information in order to easily navigate through the application. The actual problem is a gap that exists between users' needs and business experts priorities. The goal of this paper is to describe a new approach to analyze data obtained from Card Sorting experiments considering different sources of information such as business requirements and usability experts' opinions. Particularly, we investigate how to apply Vertical Fragmentation algorithms, developed as an alternative for hierarchical clustering in distributed databases, to the Card Sorting problem and how to interpret the output.
