Bridging the Knowledge Gap between Transactional Databases and Data Warehouses

Normal 0 false false false EN-US X-NONE X-NONE Data warehouse is widely recognized in the industry as the principal decision support system architecture and an integral part of the corporate information system.  However, the majority of academic institutions in the US and world-wide have been slow in developing curriculums that reflect this reality.  This paper examines the issues that have contributed to the lag in the coverage of data warehousing topics at universities.</p

Spatial pattern of structural ageing in eastern Croatia: evolution and explanations

The article aims to examine the ageing situation and social policy issues in the Osijek-Baranja County of Eastern Croatia. Using historical evidence from Census data, the research suggests that the evolution of the ageing pattern has been mainly determined by such factors as development of the transport system; changes in political-territorial organisation; supply of jobs in the cities; deagrarianisation and a domestic war in the 1990s. The increased importance of urban centres, through planned industrialisation and administrative centralisation, has accelerated and intensified rural-to-urban migration. Consequently, the spatial pattern of structural ageing has been substantially affected. A significant variation was found in urban and rural areas and also within sub-regional units. The findings suggest that the evolution of spatial disparities in the ageing pattern has been due to unplanned migration; also to spatial differences in the level of socio-economic development; the influence of tradition, such as higher fertility rates historically in some areas and suburbanisation, notably around the city of Osijek. The article concludes that ageing is affecting the country’s economic growth and the formal and informal social support systems including the provision of resources for older citizens in the endangered areas

Public Investments and Borrowing: New Challenges for the Local Governmetns in Eastern Croatia

In Croatia there is recognized growing interest and effort gain by authorities to give all areas equal opportunities to gain economic and social resources above all needed for EU accession. Allocation of budget which can ensure expected quick economic growth of eastern parts of Croatia justifies budget deficit. The paper shows necessity to accept a challenge of change the mainstream of financing capital investments because conventional patterns slow down and make difficult to run development projects. There is a great extend of opportunities of financial sources but not used in enough scale. The goal is to answer on questions: what kind of sources of financing are suitable to use in public sector, and is their current way of borrowing fit efficiently enough to be adequate for quick economic development? This paper contributes in attempt to present some solutions to problem of areas legged behind in Eastern Croatia which plead for strengthening development and economic prosperity because nominated projects for public goods exceed their budgets possibilities. Many factors depend about financial productivity of local units. For that purpose the current mainstream of public debts will be considered. The potential of different pattern of public debt will be foreseen and at the same time identify the possibilities which could bring new patters of financing public investments like involvement of private sector in projects of public interest like public-private partnership.public investment, debt, means of finance, local development.

Employing a Multilevel Secure Approach in CRM Systems

This research shows how Multilevel Secure (MLS) data models can be used in a Customer Relationship Management (CRM) context. MLS models were originally developed as database models for the management of information in environments characterized by a strict hierarchy of security levels, such as military institutions and government security agencies. Improvements in evolving database technologies have made MLS data modeling practical as well as theoretically appealing. This paper illustrates how an MLS model can be used as a part of the technology for coordinating business-customer interactions with the objective of building long-term customer loyalty. Several examples are used to show how organizing a database management system based on MLS principles can be used to help businesses provide consistent and appropriate content to various customers and partners. Improvements in flexibility and cost of applications, as well as opportunities for new CRM strategies, are discussed as potential benefits of integrating MLS and CRM technology

STRATEGIC APPROACH IN MODEL OF SCHOOLING ”K-12”

Electronic learning is such aspect of modern learning where lectures, examination or instruction performs exclusively through Internet, while the percentage of learning and using ICT is over 80%. Key elements of e-learning pattern are technological mainframe, curriculum, interaction, strategic management and marketing. Model K-12 gives his contribution in organization of education and time flexibility, provides quality communication and gains higher profit. The paper addresses model of schooling K-12 which needs to be compared with current stage in Republic of Croatia. It is confusing that the term of e-learning industry still does not find itself in Croatian economical terminology, although its value in 2008 was ranked on 38 billions of euros.e-learning, model K-12, education management, KM, ICT

A Framework for Collecting and Defining Requirements for Data Warehousing Projects

In this paper we address the issue of failure of data warehousing projects due to inadequate requirements collection and definition process. We describe a framework that can help accomplish the objective of developing a business-driven, actionable set of requirements. The framework consists of a series of steps to facilitate collection and definition of requirements in data warehousing projects. The paper also addresses the difficult yet common issue of end-users’ limited availability during the requirements collection process and proposes an approach that can serve to alleviate this problem

Teradata University Network: A No Cost Web-Portal for Teaching Database, Data Warehousing, and Data-Related Subjects

This paper describes the value that information systems faculty and students in classes dealing with database management, data warehousing, decision support systems, and related topics, could derive from the use of the Teradata University Network (TUN), a free comprehensive web-portal. A detailed overview of TUN functionalities and content is given. Freely available resources, such as software tools, large corporate data sets, case studies, and exercises are detailed. Various ways in which the TUN resources can facilitate teaching and learning processes are discussed. The zero-installation, zero-maintenance, zero-cost TUN paradigm is explained

Localization of the epileptogenic foci using Support Vector Machine

Epileptic foci localization is a crucial step in planning surgical treatment of medically intractable epilepsy. The solution to this problem can be determined by the detection of the earliest time of seizure onset in electroencephalographic (EEG) recordings. This study presents the application of support vector machine (SVM) for localization of the focus region at the epileptic seizure on the basis of EEG signals. We used intracranial EEG recordings from patients suffering from pharmacoresistant focal-onset epilepsy. We have been investigating a localization of the focus region at the epileptic seizure based on SVM to detect the onset of seizure activity in EEG data. The SVM is trained on sets of intracranial EEG recordings from patients suffering from pharmacoresistant focal-onset epilepsy. The performance of SVM is measured by using accuracy obtained from a fit between the target value and network output. Our EEG based localization of the focus region at the epileptic seizure approach achieves 97.4% accuracy with using 10-fold cross validation. Therefore, our method can be successfully applied to localization of the epileptogenic foci
