Along with the rapid expansion of information technology and the urgent demand of Decision Support System, only in a few years, data warehouse have been converting absolute theory into practical technology. More and more enterprises have been plunging into the data warehouse system for supporting business process and decision. Data warehouse system does transfer big data of enterprise to useful resource or information and will not impact current history data. The data warehouse depends on enterprise various demands and plays the role of Decision Support System. It is the reason that enterprise pays attention and positive investment. This paper identifies as a set of evaluating criteria on the literature review and consults the expert to decide vendor level, design the questionnaire and retrieve weight. At last the paper uses the real case evaluating data warehouse system by ELECTRE I. The result of this study can not only contribute to the understanding of functionalities of a data warehouse system but can provide a practical guideline for selection of a data warehouse system.

Taiwanese society perceives English as an important skill; most people expend significant efforts and resources to learn English. However, Taiwanese education focuses exclusively on traditional teaching in language courses, overlooking interactions and cultural concepts. Thus, students' ability to communicate orally in English remains relatively low. Existing literature indicates that Computer-Assisted Language Learning (CALL) can enrich language learning as computers provide many functions to enhance lectures in a meaningful and effective manner. In particular, CALL can incorporate speech recognition software to help develop oral language and practice pronunciation. Integrating CALL technology into traditional language courses may improve Taiwanese students' oral performance. The current study utilized learner-centered design and second language acquisition theories as guidelines to identify relevant software; the SECTIONS model and evaluation criteria were used to select the most suitable program for integration into a traditional course. The experimental design was administered to two sophomore English classes whose students were not majoring in English at a private university in Taiwan over an eight-week period. Pre- and posttests were used to identify language achievement during the study while a questionnaire was administered to determine attitudes toward using the software. Changes in the Spoken English Test (SET) resulting from the treatment were found to have no statistically significant difference, but the experimental group demonstrated greater improvement on the sentence mastery section and vocabulary. The perceived usefulness and the subject norm had a significant and strong influence on the adoption and use of computer technologies in participants' English oral practice.

Innovation and technology advancements in information systems (IS) result in multiple product offerings and business intelligence (BI) software tools in the market to implement business intelligence systems (BIS). As a result, a high proportion of organisations fail to employ appropriate and suitable software tools meeting organisational needs, resulting in a prime number of BI solution failures and abandoned projects are therefore recorded. Due to such project failures, benefits associated with BI are not realised hence organisations loose enormous investments on BI solutions and competitive advantage. The study aims at discovering and exploring critical factors influencing the selection of BI tools when embarking on the selection process. This is a quantitative research study and questionnaire surveyed data was collected from 92 participants working in South African financial services providers listed on the Johannesburg Stock Exchange (JSE) appearing in the top 100 based on market capitalization. The data was analysed quantitative by employing the use of SPSS and SmartPLS-3 software's to test the significance of influential factors using the proposed conceptual model that emerged from the literature. The findings showed that a combination of domain technical and non-technical factors is critical. Therefore, software tool technical factors (functionality, ease of use, compatibility, availability of an integrated hardware/software package, and availability of source code), vendor technical factors (availability of technical support, technical skills, quality of product, availability of user manual for important information, tutorial for learning and troubleshooting guide, and experience in using product developed by the same vendor), and opinion non-technical factors (end-users, subordinates, outside personnel acquaintances, and improvement in customer service) emerged as significant combination of influential factors to be considered. The study contributes to both academia and industry by providing influential determinants for software tool selection. It is hoped that the findings presented will contribute to a greater understanding of factors influencing the selection of BI tools to researchers and practitioners alike. Furthermore, organisations seeking to select and deliver appropriate BI tools will be better equipped to drive such endeavours.

Recently, the interest in the business application of analytics and data science has increased significantly. The popularity of data analytics and data science comes from the clear articulation of business problem solving as an end goal. To address limitations in existing literature, this dissertation provides four novel design artifacts for Knowledge Discovery via Data Analytics (KDDA). The first artifact is a Snail Shell KDDA process model that extends existing knowledge discovery process models, but addresses many existing limitations. At the top level, the KDDA Process model highlights the iterative nature of KDDA projects and adds two new phases, namely Problem Formulation and Maintenance. At the second level, generic tasks of the KDDA process model are presented in a comparative manner, highlighting the differences between the new KDDA process model and the traditional knowledge discovery process models. Two case studies are used to demonstrate how to use KDDA process model to guide real world KDDA projects. The second artifact, a methodology for theory building based on quantitative data is a novel application of KDDA process model. The methodology is evaluated using a theory building case from the public health domain. It is not only an instantiation of the Snail Shell KDDA process model, but also makes theoretical contributions to theory building. It demonstrates how analytical techniques can be used as quantitative gauges to assess important construct relationships during the formative phase of theory building. The third artifact is a data mining ontology, the DM3 ontology, to bridge the semantic gap between business users and KDDA expert and facilitate analytical model maintenance and reuse. The DM3 ontology is evaluated using both criteria-based approach and task-based approach. The fourth artifact is a decision support framework for MCDA software selection. The framework enables users choose relevant MCDA software based on a specific decision making situation (DMS). A DMS modeling framework is developed to structure the DMS based on the decision problem and the users' decision preferences and. The framework is implemented into a decision support system and evaluated using application examples from the real-estate domain.

The final thesis deals with computerized book-keeping and accounting software evaluation. The thesis is devided into 5 chapters. The initial four chapters are focused on history of book-keeping, legal regulation of computerized book-keeping, ICT impact on book-keeping and accounting software selection criteria. The last chapter is dedicated to the evaluation of the specific accounting software ACONTO.

Os Sistemas Integrados de Gestão, também conhecidos como ERP (Enterprise Re-source Planning), vem tendo ampla utilização nas organizações a partir dos anos 90. Por exigir um investimento de elevado valor financeiro para a sua implantação, os responsáveis pela sua aquisição devem tomar cuidados especiais, uma vez que os seus resultados positivos ou negativos somente surgem após longo período de im-plantação, às vezes após muitos anos. Sendo um problema complexo, repleto de incertezas e riscos, os decisores tomam muito de seu tempo para analisar os diver-sos critérios e funcionalidades das ofertas de sistemas recebidas. A tese objetiva apresentar um procedimento que possibilite às empresas, em particular as de pe-queno e médio porte, um procedimento que as permita analisar quando do interesse da aquisição de um ERP, qual das ofertas disponíveis estará mais adequada às su-as necessidades de negócio, baseado em um método multicritérios de apoio à deci-são. A revisão da literatura analisa os Sistemas de Informação (SI) informatizados e os principais papéis desempenhados por eles: apoio às operações, apoio à vanta-gem competitiva e apoio à decisão. A seleção das ofertas propostas foi efetuada uti-lizando o método de Estudo de Casos múltiplos em empresas que adquiriram esses sistemas,ghy utilizando o ANP (Analytic Network Process) como instrumento de pesquisa. Para se estabelecer uma classificação dos critérios utilizados na análise foi utilizada a Técnica Delphi, a qual foi realizada junto a especialistas em Tecnologia de Informação. O resultado obtido pelo Estudo de Casos mostrou que o procedimen-to proposto é válido e pode ser utilizado por empresas de todos os portes. / The use of Integrated Management Systems, also known as ERP (Enterprise Re-source Planning), are widely accepted by organizations since beginning of the ni-neties. As its implementation means a high financial value investment, the respon-sible team for its acquisition has to take special cares, once their positive or nega-tive results will appear only after long implementation period, often after many years. As it is a complex decision problem, evolving uncertainties and risks, the decision agents spend a lot of time to analyze the several criteria and functional-ities from received offers. This thesis presents a proposal which makes possible the companies, particularly those of small or medium sizes, which allows to analyze during the ERP acquisition phase, the available offers more adapted to their business requirements, based on a multi-criteria support decision method. The literature revision analyzes the computerized Information Systems (IS) and the main roles carried out by them: operations support, competitive advantage support and decision support. In order to define the criteria set used in the multi-criteria analysis, the Delphi Method was used and it was answered by Information Technology experts. These criteria was used to classify the ERP\'s offers using the multiple cases study using ANP (Analytic Network Process) as research tool.. The results obtained by case study in four companies were used to validate several propositions.

Database management and systems represent the core of the change and the key of the new revolution of the information technology and infrastructure. Business information and models have been stored and manipulated through the use of the database technology. Due to the fast growing speed and variety of the database products in the marketplace, managers are having difficult making the right decision in selecting and maintaining the Internet database management and systems. To tackle this issue, we propose a requirements-based software selection model from the user’s viewpoint. In this research, we develop a five-step choice model with an emphasis on the requirement analysis and rank analysis. We collect and compile the functional and non-functional characteristics and features of the Internet database management and systems. We classify and organize them into a four-layer hierarchy and work with the weight mechanism in the rank analysis. This choice model adopts another five-part rank policy in order to produce the final suggestion of software selection. In the end, we apply the new model in a field case study of the Web Database Systems Procurement Project with the National Laboratories of Foods and Drugs, Department of Health, Executive Yuan.
