|Master's Thesis: A GENERALIZED FRAMEWORK FOR MONITORING CHANGES TO DATABASE RELATIONS USING ACTIVE CAPABILITY|
Current data-driven applications operate in a global context with shared data being modified by several applications. Database
management systems (DBMSs) provide mechanisms for sharing large amounts of data and manipulating them by many concurrent users in a consistent manner. However, they were not designed to support monitoring of subsets of relations by multiple users when they
are being changed or manipulated by several users. In many applications, it is not only necessary to monitor these subsets but also to visualize the changes in some way. For example, in one of the applications, the track relation is being updated with respect to tracks (or objects) and their
positions by multiple sources. Many users monitor subsets of these tracks as needed for their use (e,g, different regions).
