Efficient, effective, and trustworthy collaboration in design is vital to maintain organizational competence. Conventional access control methods are too coarse in inter-organizational lean and secure data exchange. In this paper, a Scheduled Role-Based Distributed Data Access Control Model is described to support data security management in a distributed environment. The model allows for fine-grained data access control at both the server and client sides, thus securing different levels of design information dissemination for intellectual property protection purposes. Common interface for heterogeneous data is built based on XML.

The necessity of having intelligent methodology to access databases in networks has become more apparent in the age of distributed networks. Using semantics and ontologies can be highly helpful in developing such methodologies, as they provide the required classifications and mined information. The necessities that are required by the database administrator to build durable, reliable, and flexible data access methodology have been highly appreciated. This study that compares between the proposed system and conventional methods, for example Role Based Access Control (RBAC) and classical chain-based methods. The comparison is done using applications in the healthcare sector. This study is based on real surveys that have been conducted in an active hospital in the State of Kuwait.
