Using Reference Models for Data Warehouse Metadata Management

Based on experience from applying the Common Warehouse Metamodel to metadata management at a large Swiss bank, the applicability of metadata reference models in complex application domains is analyzed. In order to explain the context of the case, the state-of-the-art of the Common Warehouse Metamodel and its application for data warehouse management are summarized. Based on the project experience documented in this paper, benefits of the reference model approach are described and recommendations for future developments of the Common Warehouse Metamodel are proposed

Об одном из методов разработки концептуальной объектно-ориентированной многомерной метамодели информационно-аналитической системы

Object-oriented approach provides essential advantages in multidimensional modeling. The question of information analytical system multidimensional metamodel development is considered in this paper very closely. It is offered to use widely the methods based on standards in the field of the multidimensional analysis: Meta Object Facility (MOF), Common Warehouse Metamodel (CWM), Unified Modeling Language (UML).Объектно-ориентированный подход предоставляет существенные преимущества в многомерном моделировании. В статье разбираются вопросы разработки многомерной метамодели информационно-аналитической системы. При этом предлагается широко использовать методы, основанные на традиционных технологиях в области многомерного анализа данных: Meta Object Facility (MOF), Common Warehouse Metamodel (CWM), Unified Modeling Language (UML)

A model-based software architecture for XML data and metadata integration in data warehouse systems

This project is carried out to develop a system prototype of an electronic tendering (e-Tender) system.Several steps have been taken starting with information gathering and analyzing, developing a prototype, and ending in system testing.The prototype was further tested with real users to analyze the document flow speed.In conclusion, e-Tendering system has a better approach compared to the manual process of tender. The document flow speed was increased by 58.5%, which suggests a more efficient process

Dynamic Model-based Management of Service-Oriented Infrastructure.

Models are an effective tool for systems and software design. They allow software architects to abstract from the non-relevant details. Those qualities are also useful for the technical management of networks, systems and software, such as those that compose service oriented architectures. Models can provide a set of well-defined abstractions over the distributed heterogeneous service infrastructure that enable its automated management. We propose to use the managed system as a source of dynamically generated runtime models, and decompose management processes into a composition of model transformations. We have created an autonomic service deployment and configuration architecture that obtains, analyzes, and transforms system models to apply the required actions, while being oblivious to the low-level details. An instrumentation layer automatically builds these models and interprets the planned management actions to the system. We illustrate these concepts with a distributed service update operation

Towards a meaningful manufacturing enterprise metamodel: a semantic driven framework

This paper presents a deep investigation and an interdisciplinary analysis of the collaborative networked enterprise engineering issues and modelling approaches related to the relevant aspects of the semantic web technology and knowledge strategies. The paper also suggests a novel framework based on ontology metamodelling, knowledge model discovery, and semantic web infrastructures, architectures, languages, and systems. The main aim of the research enclosed in this paper is to bridge the gaps between enterprise engineering, modelling, and especially networking by intensively applying semantic web technology based on ontology conceptual representations and knowledge discovery. The ontological modelling approaches together with knowledge strategies such as discovery (data mining) have become promising for future enterprise computing systems. The related reported research deals with the conceptual definition of a semantic-driven framework and a manufacturing enterprise metamodel (ME_M) using ontology, knowledge-driven object models, standards, and architectural approaches applied to collaborative networked enterprises. The conceptual semantic framework and related issues discussed in this paper may contribute towards new approaches of enterprise systems engineering and networking as well as applied standard and referenced ontological models

AOSD Ontology 1.0 - Public Ontology of Aspect-Orientation

This report presents a Common Foundation for Aspect-Oriented Software Development. A Common Foundation is required to enable effective communication and to enable integration of activities within the Network of Excellence. This Common Foundation is realized by developing an ontology, i.e. the shared meaning of terms and concepts in the domain of AOSD. In the first part of this report, we describe the definitions of an initial set of common AOSD terms. There is general agreement on these definitions. In the second part, we describe the Common Foundation task in detail
