Title: Active database management of global data integrity constraints in heterogeneous database environments
Authors: Do, Lyman
Drew, Pamela
Issue Date: 1995
Series/Report no.: Computer Science Technical Report ; HKUST-CS95-1
Abstract: Today, enterprises maintain many, disparate information sources over which complex business applications are executed. The informal and ad hoc characteristics of these environments make the information very prone to inconsistency. Yet, the flexibility of application execution given to different parts of an organization is desirable. This paper introduces a new mechanism in which the execution of asynchronous, pre-existing, yet related, applications can be harnessed. A multidatabase framework that supports the concurrent execution of these heterogeneous, distributed applications is presented. Using this framework, we introduce an intuitive conceptual model and algorithm for the enforcement of interdatabase constraints based on active database technology.
