Traditionell wird Vertraulichkeit bei ausgelagerten Daten durch das den Serviceprovidern entgegengebrachte Vertrauen, durch vertragliche regelungen zum Datenschutz sowie Mechanismen zur Zugriffskontrolle und - protokollierung erreicht. Zunehmende Datendiebstähle und dadurch verursachte Schäden erfordern weitere technische Maßnahmen. Sichere Datenverschlüsselung und effiziente Abfragebearbeitung sind schwierig gemeinsam zu erreichen, sodass diesbezüglich oft Kompromisse eingegangen werden. Gleichzeitig bestehen Wahlmöglichkeiten hinsichtlich der Entscheidung, ob Datenverschlüsselung und Abfragebearbeitung am Server oder am Client stattfindet.

data Integration is a well elaborated scientific area and one of the most important use cases of the Semantic Web. Techniques developed in this field aim at providing interoperability between heterogeneous data sources. Compared to typical Semantic Web use cases, data integration issues are manifold and also affect applications through their underlying schemas. Civil engineers specialized in risk and measurement analysis need a reliable Decision Support System (DSS) that integrates various required techniques. Hence, Structural Health Monitoring (SHM) applications tend to adopt typical integration concepts, but not by regarding data and their semantics independent from the application domain. Instead, such a DSS should be accessible in an integrated manner to support the usage of methods and techniques from different systems according to their intended operational purpose. This paper presents some practical examples of using data Mining operations which enable a better understanding of the analysed data and which can be successfully integrated into a unified DSS for SHM.

Active database systems use situation-action rules to define which action has to be taken vt hen a particular situation occurs. Situation diagrams, which are introduced in this paper, provide a high-level graphical representation of situations for the conceptual design of active object-oriented databases. A situation is specified declaratively as a graphical query with temporal and logical conditions over members of object classes, event classes, and interval classes.
