  1. 31. View Integration in Conceptual Database Design : Problems, Approaches and Solutions

    Författare :Peter Bellström; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Systems; Informatik;

    Sammanfattning : View integration is a complex and time-consuming task because there are several problems that need to be addressed. Two such problems are conflict identification and conflict resolution. Conflicts occur because end users may define concepts on different levels of abstraction and because end users may name concepts differently. LÄS MER

  4. 33. Data management in control applications : a proposal based on active database systems

    Författare :Esa Falkenroth; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Active database management systems can provide general solutions to data management problems in control applications. This thesis describes how traditional control algorithms and high-level operations in a control system can be combined by using an embedded active object-relational database management system as middleware.
