A user driven method for database reverse engineering Barbar, Aziz In this thesis we describe the UQoRE method which supports database reverse engineering by using a data mining technique. Generally, Reverse Engineering methods work by using information extracted from data dictionaries, database extensions, application programs and expert users. The main differences between all these methods rely on the assumptions made on the a-priori knowledge available about the database (schema and constraints on attributes) as well as the user competence. Most of them are based on the attribute name consistency. This paper presents a method based on user queries. Queries are stored in a “Query Base” and our system mines this new source of knowledge in order to discover hidden links and similarity between database elements.

Developing foundations for knowledge management systems Dorit Nevo, Yair Wand Knowledge Management (KM) is an important issue in organizations. However there are several barriers to successful KM. In particular, knowledge hoarding, difficulties in identifying organizational knowledge, not understanding KM requirements, and technical difficulties of knowledge representation. In this work we focus on a connection between the managerial and technical aspects of knowledge management. We study the nature of organizational knowledge in order to derive knowledge management requirements to support the design of computerized Knowledge Management Systems. The work consists of three parts: 1) Defining organizational knowledge that needs to be managed. 2) Using the definition of organizational knowledge and its attributes to identify knowledge management requirements. This involves identifying the various facets of knowledge as well as the perceived meta- knowledge requirements of users. 3) Deriving guidelines for the efficient design of knowledge management systems.

Developing Internet-based integrated architecture for managing globally distributed software development projects Kotlarsky, Julia Given the increasing importance of globally distributed software development (GDSD) over the last decade, it is surprising that empirical research in this area is still in the very early stage. The few existing suggest that traditional coordination and control mechanisms can be effective for these projects only with support from appropriate information technology. However, at present, little is known about the success of current Information and Communication Technology (ICT) support in the context of GDSD projects. Therefore, the main question this research addresses is what ICT-based support is appropriate for globally distributed software development projects? The objectives of this research are to elicit and develop the functional requirements for ICT support for GDSD projects, to analyze the gap between existing tools and these requirements, and to develop an Internet-based integrated architecture of tools that would fill these gaps.

Dynamic management for business processes modeling & execution in workflows Golani, Mati Contemporary workflow-management systems cannot represent change or evolution of business processes. When a change is needed due to external reason, an offline procedure is invoked in order to create a new workflow engine template for the future instances in the workflow enactment module. The standard interfaces do not deal with the business process metadata in a way that can actually change it as a reaction to inbound knowledge. There are many relevant cases, especially in the virtual enterprise arena, where the business process is not deterministic and is influenced by external parameters (such as the selection of virtual partners), so the knowledge of what should be done is available, however it is external to the system. There is a need to develop a modeling mechanism that enables to transfer process definitions in an automatic way, without the need for human interference. One way of confronting with these issues is the use of a rule-based engine to monitor business process execution. This engine will contain internal meta-rules that refer to metadata entities, i.e. rules that describe how to act on other rules (business process routing) when a change is detected, while executing all needed consistency checks.
