Metadata Repository Support for Legacy Knowledge Discovery in Public Administrations [chapter]

Adriana Maria C. M Figueiredo, Aqueo Kamada, Luciano L Damasceno, Marcos Antonio Rodrigues, Manuel de Jesus Mendes
2004 Lecture Notes in Computer Science  
In this paper we examine how a MOF-based repository can support the definition, modeling, exchanging and integration of metamodels created for legacy knowledge discovery.  ...  The OMG has issued a request soliciting proposals for a metamodel to capture knowledge from legacy systems (referred to as the Legacy Knowledge).  ...  The prime purpose of these mappings is to define a generic framework for managing, in terms of repository, the metadata described by the metamodel.  ...

Challenges in Efficient Data Warehousing

Muhammad Arif, Faheem Zaffar
2015 International Journal of Grid and Distributed Computing  
Data warehousing has proved its importance as a source of decision support in competing market strategies and thus a lot of work is carried out in various aspects of it like conceptual enterprise perspective  ...  Future Work Meta model described for quality of data and quality of service is partially validated. Software tools and applications are required; those can fully validate the proposed model.  ...  CWM is based on the following OMG standards: UML, MOF (Meta Object Facility), a Meta modeling and meta-data repository standard, and XMI, an XML-based standard for metadata exchange originating from OMG  ...

An Architecture Framework for Complex Data Warehouses [article]

Jérôme Darmont, Omar Boussaid, Jean-Christian Ralaivao, Kamel Aouiche
2007 arXiv   pre-print
Then we present a general architecture framework for warehousing complex data.  ...  This architecture heavily relies on metadata and domain-related knowledge, and rests on the XML language, which helps storing data, metadata and domain-specific knowledge altogether, and facilitates communication  ...  Furthermore, they are adapted to reasoning for metadata exploitation.  ...

A Standard for Representing Multidimensional Properties: The Common Warehouse Metamodel (CWM) [chapter]

Enrique Medina, Juan Trujillo
2002 Lecture Notes in Computer Science  
Then, CWM-compliant tools could interoperate by exchanging their CWM-based metadata in a commonly understood format and benefit of the expressiveness of the MD model at the conceptual level.  ...  Data warehouses, multidimensional databases, and OLAP tools are based on the multidimensional (MD) modeling.  ...  Acknowledgements We would like to thank the CWM committee, especially David Mellor and John Poole, for their useful ideas and support in the writing of this paper.  ...

Towards Introducing User Preferences in OLAP Reporting Tool [chapter]

Natalija Kozmina, Darja Solodovnikova
2012 Lecture Notes in Business Information Processing  
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.  ...  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.  ...  OLAP Reporting Tool All operation of the data warehouse framework and the OLAP reporting tool as a part of it is based on metadata that consists of five interconnected layers ( fig. 1 ).  ...
