Applying JAVA-Triggers for X-Link Management in the Industrial Framework

Abstract

This chapter focuses on referential link integrity problems. In the industrial context, the life cycle of a document plays a central role in describing the “steps out” of a product. Users realize some manipulations like creation, edition, suppression and querying under a multi-user environment, risking possible destruction or the alteration of the document’s integrity. A classical impact is the infamous “Error 404: file not found.” However, the user needs a notification alert mechanism to prevent and warrant the coherence of manipulations over all the life cycle processes of a product. The main objective of this chapter is to provide a generic relationship validation mechanism to remedy this shortcoming. We believe in the combination of some standard features of XML, specifically XLL specification as a support for integrity management and Java-Triggers approach as an alert method. This study, compared with actual approaches, proposes a solution based on active functionalities.
