E-CARe: A Process for Engineering Ubiquitous Information Systems

Ubiquity in Information Systems ISs is a new requirement widely expressed by customers and users due to emerging and evolving communication and mobile technologies. Each IS should support a set of mobile applications used either to interact smartly with the changing environment, to provide adaptive services to customers or both. Designing ISs with highly technological risks requires a precise and appropriate development process. However, such processes fail to consider ubiquitous requirements throughout the development process. This paper tries to solve this issue by proposing a process for identifying and modeling ubiquitous requirements that can be integrated into an existing IS engineering process. This process, called E-CARe, focuses on adapting to the surrounding context; this requires detailed specification and analysis work by a context designer. E-CARe uses an event-driven logic, as dynamicity and reactivity are the major properties required from ubiquitous applications. A Model-Driven Engineering MDE approach is used to automate specification work. In order to test the process, a case study from the intelligent transport domain is applied as an illustration.

A CASE Tool for the Modeling of Methods and Information Systems

MODSI is a multi-models tool for information systems modeling. A modeling process in MODSI can be driven according to three different approaches: informal, semi-formal and formal. The MODSI tool is therefore based on the linked usage of these three modeling approaches. It can be employed at two different levels: the meta-modeling of a method and the modeling of an information system.
