Ever-increasing demands for high transaction rates, limitations of high-end processors, high availability, and modular growth considerations are all driving forces toward distributed architectures for transaction processing. However, a prerequisite to taking advantage of the capacity of a distributed transaction processing system is an effective strategy for workload allocation. The distribution of the workload should not only achieve load balancing, but also support an efficient transaction processing with a minimum of intersystem communication. To this end, adaptive schemes for transaction routing have to be employed that are highly responsive to workload fluctuations and configuration changes. Adaptive allocation schemes are also important for simplifying system administration, which is a major problem in distributed transaction processing systems. In this article we develop a taxonomic framework for workload allocation, in particular, transaction routing, in distributed transaction processing systems. This framework considers the influence of the underlying system architecture (e.g., shared nothing, shared disk) and transaction execution model as well as the major dependencies between workload, program, and data allocation. The main part of the framework covers structural (or architectural) and implementational alternatives for transaction routing to help identify key factors and basic tradeoffs in the design of appropriate allocation schemes. Finally, we show how existing schemes fit our taxonomy. The framework substantially facilitates a comparison of the different schemes and can guide the development of new, more effective protocols.

This thesis deals with the area of management of business informatics at the Floorball Union. It is a very specific type of organization with a mixed organization structure and decision-making processes divided between elected bodies and the employee structure of the organiza-tion, where the area of business informatics is, due to the mission and goals of the organiza-tion, rather at the periphery of the interest of the management of this sports association. It is so despite the fact that the floorball union has developed and runs its own information system FIS. Based on the knowledge and experience acquired in the theoretical part, the thesis aims at assessing the current model of management of business informatics, defining its biggest shortcomings and proposing adjustments to this model. Within the assessment of the management model, the thesis further evaluates the benefits of the implementation of the infor-mation system FIS, with the aim of evidencing the rightness of the decision to develop and implement the system, both from the point of view of non-financial benefits, as well as financial impacts and possibilities of further development and growth of the organization. The theoretical part of the thesis contains a description of the structure, goals and mission of the sports association, and attention is then devoted to the selected models, frameworks and approaches to management of business informatics and measuring its benefits. The practical part is devoted to an analysis of the current state of management of business informatics, and it includes a description of all its resources and relations, as well as a definition of its biggest shortcomings. Based on the findings, I have proposed a centralization of the management model including proposals of specific measures that will eliminate the discovered shortcom-ings to maximum extent. Compared to standards, the model of management of business in-formatics has been in some areas adjusted according to the needs, requirements and characteristics of the organization for which it is being designed. Another significant part of the practical part of the thesis contains evidence regarding the benefits of the implementation of the information system FIS. It is this part in particular, along with the creation of a new model of company information system management for the Czech Floorball Union, that I consider the most significant contribution of my diploma thesis.

This diploma work deals with the information system assessment and proposal for its modification. The theoretical part describes the basic concepts and issues related to information systems. The analytical part of assessing information system according to the methods for determining the current state. The design part is based on the analytical part and the main goal of this section is to design changes to improve the current situation with the subsequent economic evaluation.

<p>The web and digital technologies have been continuously growing in the recent five years. The data generated from the Internet of Things (IoT) devices are heterogeneous, increasing data storage and management difficulties. The thesis developed user-friendly data management system frameworks in the local environment and cloud platform. The two frameworks applied to two applications in the industrial field: the agriculture informatics system and the personal healthcare management system. The systems are capable of information management and two-way communication through a user-friendly interface. </p>
