Towards Introducing User Preferences in OLAP Reporting Tool

Abstract

Abstract. This paper presents an OLAP reporting tool and an approach for determining and processing user OLAP preferences, which are useful for generating recommendations on potentially interesting reports. We discuss the metadata layers of the reporting tool including our proposed OLAP preferences metamodel, which supports various scenarios of formulating preferences of two different types: schema-specific and report-specific. The process of semantic metadata usage at the stage of formulating user preferences is also considered. The methods for processing schema-specific and report-specific OLAP preferences are outlined.

Towards an approach to integration of the viewpoint concept into the CWM

“…Another work introduces user preferences in OLAP reporting tool [19], and have used the CWM as a basis of the metadata to determine and process user OLAP preferences in order to generating recommendations on interesting reports, but, this work was restricted to only specific packages of the CWM.…”

Adding Recommendations to OLAP Reporting Tool

“…OLAP preferences metadata stores definitions of user preferences on reports' structure and data. The detailed description of each layer and its interconnections can be found in (Kozmina and Solodovnikova, 2012).…”
