It is for this reason that the diploma thesis deals with the issue of information system in the context of its management and security in terms of services provided by the selected organization. The aim of the diploma thesis is to choose a selected information system in the context of a selected company. The work based on its evaluation provides views on its effectiveness and efficiency. Through its evaluation, the work presents its own proposal for its improvement.

This study investigates the effect of locus of control on the relationships among product innovation, management accounting system (MAS), and organizational performance. 300 participants were randomly drowned from the electronic industries¡¦ managers in Taiwan Security Exchange and 132 useful responses were used to validate the hypotheses by path analysis. The results shows that: 1. Product innovation and organizational performance have a significant positive relationship 2. Product innovation and perceived usefulness of MAS information have a significant positive relationship 3. Perceived usefulness of MAS information and organizational performance are positively correlated 4. Product innovation has an indirect effect on organizational performance through perceived usefulness of MAS information 5. When managers tend to be internal locus of control, the linkage between product innovation and perceived usefulness of MAS information will be stronger 6.When managers tend to be internal locus of control, the linkage between perceived usefulness of MAS information and organizational performance will be stronger. However, when manager tend to be external locus of control, the hypothesis between perceived usefulness of MAS information and organizational performance is not supported. Management implications of this study are suggested. Businesses facing the global competition have to adopt the strategies of product innovation to create profits, promote market shares and improve strength of competition and then achieve organizational performance. Business using higher degree of MAS information will improve their adopting strategy of product innovation and enhance their organizational performance. Managers with internal locus of control will aggressively use MAS information and improve the linkage between product innovation and organizational performance effectively.

For the runtime phase of automated information system lifecycle is typical a frequent change of system quality requirements. Only systems that can adapt to these requirements are successful in its environment. The system change can be each time of different extensive. If it is necessary for satisfaction of new requirements to add, remove or change some system components and its relations than we talk about system architecture change. This action is so large-scale that it is very risky to implement it without appropriate control and management. This essay addresses these changes and its management. Main phases of the process and its activities are proposed. The suggestion is based on the development process of new systems and available literature from this area. The target of the essay is to offer a certain framework for the change process management. Introduction to iformation system architecture is the first part of the essay. The last part is then concerned in a practical example of information system architecture change and its evaluation.

The thesis describes the design of the information system that is supposed to support production process at the Varia, Ltd company. Theoretical background of operative production management and information systems is described in the first part. The second part contains the analysis of the processes inside company in which the problematical areas were identified. Based on the analysis results and the theoretical background, the particular design of information system was created. This system is supposed to support operative production management and to eliminate the production process weaknesses.

This quantitative research study investigated the impact of organisational context on the process and success of strategic IS planning (SISP) in post-implementation information systems in Libyan organisations. A set of direct and indirect relationships were investigated in the research model. The organisational context presented as a contingent situational variable mediated by SISP process and predicted by SISP success (the criterion variable). The causality of the relationship set was developed from the contingency theory of information systems and supported by fit models in strategic management research. The study deployed multivariate analysis represented in the structural equation modelling (SEM) to develop robust construct measurements and analyse data collected from executives responsible for information systems planning in both public and private Libyan organisations. Multi-dimensional multi-items constructs were used in the path analysis model after they were extensively validated. The path analysis model represented as mediation model, where hypothesise suggest that SISP context has an impact SISP success, through the influence of the SISP process. In the model, four dimensions of the SISP context construct were found to have a significant impact on SISP success directly and indirectly through the SISP process. Two of these dimensions are components of the leadership orientation construct, namely “Creative and Controlling” leadership. The other two dimensions are “Organisation centralisation structure and the Riskiness of organisation strategies”. The environmental uncertainty and planning resource constructs were found to have no impact on SISP success in Libyan organisations. Furthermore, this study validated six out of seven dimensions of SISP process construct measurement; only five exhibited acceptable fit level in the path analysis model and all were affected by the SISP context. However, just three out of five SISP process constructs had an impact on SISP success namely “Comprehensiveness, Focus and Intuition planning process”. Different SISP processes were associated with different levels of SISP success, “Intuition” was the most effective SISP process approach. The second most effective SISP process approach was the “Focus on innovation”, followed by “Limited comprehensiveness”. The SISP success measured by the fulfilment of key objectives that has three measurements constructs namely “Analysis, Alignment, and Cooperation”. The research suggest that under the effect of organisation context the most successful SISP produced by (CIO, CEO, or top executives) who rely less on personal judgment, focus more on innovation rather than control and limit their comprehensiveness of information systems planning process.

The government of Yemen has been developing government offered services designed to improve the quality of education management. Yemen's managers of education and managers of higher education in the Ministry of Education (MOE) and the Ministry of Higher Education (MOHE) have sought to improve quality of education, reduce costs, and provide timely information for decision-making processes by implementing an integrated management information system (IMIS). The problem was the lack of understanding the barriers that hinder successful IMIS implementation by the MOE and MOHE, and the role that lack of collaboration has played in prior unsuccessful attempts. The purpose of this case study was to identify barriers and success factors related to previous attempts to implement an IMIS in Yemen's MOE and MOHE. Diffusion of innovation (DOI) theory and the technology acceptance model (TAM) provided the conceptual framework. A purposeful sampling was used to select participants for semistructured interviews. The interviews were conducted with 3 ministry personnel, 8 managers, and 4 administrators from various governorates who are currently working or have worked in the Yemen MOE or MOHE. Open coding was used to identify themes and patterns. Themes were related to insufficient human and material resources, lack of understanding and acceptance of IMIS, inadequate IMIS education and training, incompetent program managers, and fear of change. These findings may contribute to positive social change by improving the management of education, thereby the overall quality of education in Yemen. Improving management in education could increase the quality of life by contributing to increase of prosperity through a better-educated society, an active citizenry, and a reduction in the level of societal violence.

DBMS are a ubiquitous building block of the software stack in many complex applications. Middleware technologies, application servers and mapping approaches hide the core database technologies just like power, networking infrastructure and operating system services. Furthermore, many enterprise-critical applications demand a certain degree of quality of service (QoS) or guarantees, e.g. wrt. response time, transaction throughput, latency but also completeness or more generally quality of results. Examples of such applications are billing systems in telecommunication, where each telephone call has to be monitored and registered in a database, Ecommerce applications where orders have to be accepted even in times of heavy load and the waiting time of customers should not exceed a few seconds, ERP systems processing a large number of transactions in parallel, or systems for processing streaming or sensor data in realtime, e.g. in process automation of traffic control. As part of complex multilevel software stack, database systems have to share or contribute to these QoS requirements, which means that guarantees have to be given by the DBMS, too, and that the processing of database requests is predictable. Todays mainstream DBMS typically follow a best effort approach: requests are processed as fast as possible without any guarantees: the optimization goal of query optimizers and tuning approaches is rather to minimize resource consumption instead of just fulfilling given service level agreements. However, motivated by the situation described above there is an emerging need for database services providing guarantees or simply behave in a predictable manner and at the same time interact with other components of the software stack in order to fulfill the requirements. This is also driven by the paradigm of service-oriented architectures widely discussed in industry. Currently, this is addressed only by very specialized solutions. Nevertheless, database researchers have developed several techniques contributing to the goal of QoS-aware database systems. The purpose of the tutorial is to introduce database researchers and practitioners to the scope, the challenges and the available techniques to the problem of predictability and QoS agreements in DBMS.
