Tiered Architecture for Remote Access to Data Sources

Teamwork is benefited by the use of shared data sources. Also, ever increasingly, organizational work depends on the activities of team members situated in different physical locations, including both employees who work from their homes and others who have been temporarily transferred to another place. Since, for all these reasons, accessing data remotely is a growing need, organizations implement internal systems in order to control shared data access according to user privileges. In this regard, the cost of resource transportation needed to generate communication must be considered. The main contribution of this paper is the extended reference layered architecture ICDFS-CV (Interface Control and Distributed File Systems - Communication Versioning). It allows to build a solution that, facilitates documents download and the creation and concurrent modification by multiple users through versioning control.
