“…Most of related works have used the extension of CWM to reach new conceptual domains: to represent the security and audit rules captured during the conceptual modeling phase of data warehouses [15], to make a conceptual metamodel for data quality and cleaning [16], to provide a relevant trace information of metadata evolution [17], and to define the metadata needed to be used in online approximate analytical processing [18].…”

The key to successful integration and interoperability between applications and software products depends on the intelligent use and management of metadata. This can be accomplished by the use of the CWM standard which provides a mechanism for exchanging metadata in the data warehousing and business intelligence domain. As for, it is known that the development and maintenance of information systems based on the user's interaction play a strategic role in the decision making process. In this paper we investigate the integration of user's viewpoint into the CWM standard to enhance reusability and interoperability of metadata during data warehouse design process.

Matchmaking plays an important role in Web services interactions. The matchmaking based on keywords easily leads to low precision, Meanwhile, the current semantic service discovery methods perform service I/O based profile matching, there exists no matchmaker that performs an integrated service matching by additional reasoning on logically defined preconditions, effects, Qos and so on. In this paper, the semantic web services are described based on Description Logics, and the services description model is designed, which describes the various aspects (such as IOPEs, Qos and so on) of the web services. So the services matchmaking is transformed into the match of concepts. The service match algorithm is proposed and the description logics reasoner RacerPro is adopted for Web services discovery. We show how the semantic matching between providers and a requester is performed by a case study.

“…Numerous proposals exist that extends CWM with different objectives: for the modeling of logical object-oriented relational data storage and the corresponding ETL process [10], for universal data mining library that implements data mining methods and algorithms [23], for recording the trace information of metadata evolution and maintain consistency during metaclass evolution [25], for representing and integrate the metadata generated by data and metadata lineage implementation [21] and for providing quality information to DW client tools [1] and for building a conceptual model for data quality and cleaning, both applicable to operational and data warehousing context. However, none of the previous proposals extend the relational metamodel from CWM with security aspects.…”

Data Warehouses (DWs) constitute a valuable support to store extensive volumes of historical data for the decision making process. For this reason, it is vital to incorporate security requirements from the early stages of the DWs projects and enforce them in the further design phases. Very few approaches specify security and audit measures in the conceptual modeling of DWs. Furthermore, these security measures are specified in the final implementation on top of commercial systems as there is not a standard relational representation of security measures for DWs. On the other hand, the Common Warehouse Metamodel (CWM) has been accepted as the standard for the exchange and the interoperability of the metadata. Nevertheless, it does not allow us to specify security measures for DWs. In this paper, we make use of the own extension mechanisms provided by the CWM to extend the relational package to specify at the logical level the security and audit rules captured during the conceptual modeling phase of the DWs design. Finally, in order to show the benefits of our extension, we apply it to a case study related to the management of the pharmacies consortium businesses.
