This diploma thesis describes Czech legislation on copyright protection of computer programs in European and international law context. The commentary is mostly focused on current, practical issues, which often aren't clearly and satisfactorily solved, or issues which are subjects of current or recent litigations before European courts. First chapter introduces special characteristics of computer programs in copyright law, shortly mentions other possibilities of their legal protection and outlines some problems connected with massive technology development and international dimension of these questions, which are enlarged in following chapters. It also defines basic terminology used in the thesis. Chapter two, called "Sources of international and European law" mainly focuses on international treaties and EU directives, on which current Czech copyright protection of computer programs is based. Following chapter describes Czech copyright protection of computer programs, respecting, in general, structure of Czech Copyright Act and simultaneously gives deeper look into selected up to date problems. It compares computer programs with traditional copyrighted works, explains i.a. concept of "employee's work" and closely focuses on author's moral and, mainly, economic rights. Special attention is dedicated...

A adoção de Software como Serviço (do inglês, Software as a Service ou simplesmente SaaS) está em expansão em todo o mundo, alavancada pelas muitas vantagens que esse modelo de distribuição de software oferece tanto para os provedores desses serviços quanto para seus clientes. Em SaaS, o provedor do serviço também é responsável pelo seu desenvolvimento e execução, o que permite a esses provedores fazerem escolhas sobre a arquitetura de seus sistemas visando diminuir a complexidade e os custos relacionados ao seu desenvolvimento e operação. Nesse contexto, um padrão de arquitetura freqüentemente utilizado é o Multitenant, que torna uma mesma instância do software capaz de servir a múltiplos clientes (tenants) simultaneamente. No entanto, sistemas que utilizam Multitenancy enfrentam uma série de desafios, principalmente no que se refere à flexibilidade em atender os requisitos específicos de cada cliente na customização de processos, de fluxos e regras de negócio, e de interfaces com o usuário. Especificamente no problema de customização de interfaces, embora existam trabalhos na literatura relacionados à customização de interfaces Web, e existam implementações de mercado de mecanismos para possibilitar essas customizações, esses trabalhos e mecanismos ou não são projetados especificamente para sistemas Multitenant ou, quando são, não têm sua arquitetura publicada e seu código fonte disponíveis para serem reutilizados. Assim, esta pesquisa investigou uma alternativa para a customização de interfaces Web no contexto de Software como Serviço Multitenant. Como resultado, foi inicialmente definido e implementado um mecanismo não intrusivo para o desenvolvimento de aplicações Multitenant chamado DORMT (Domain-Based Shared-Database Multitenancy), sobre o qual foi possível construir um mecanismo para a customização de interfaces Web, chamado MHT (Multitenant Hierarchical Themes), baseado no padrão MVC (Model-View-Controller ) e nos conceito de temas e de hierarquias / The adoption of Software as a Service (SaaS) is growing worldwide, driven by the many advantages that this software distribution model offers to both service providers and their clients. In SaaS, the service provider is also responsible for the development and the execution of the software, enabling that choices be made in terms of system architecture in order to reduce the complexity and costs related to its development and operation. However, Multitenant systems face a number of challenges, mainly related to flexibility in meeting specific customer requirements in customizing the system processes, flows, business rules and user interfaces. Specifically on the problem of user interface customization, although there are studies in the literature and products on the market that implement mechanism to allow such customizations, these studies and mechanism are not specific to Multitenant systems or the mechanism architecture and source code is not available to be reused. Thus, this study investigated alternatives for Web interfaces customization in the context of Multitenant Software as a Service. As a result, a non intrusive mechanism, called DORMT (Domain-Based Shared-Database Multitenancy), was defined and implemented to allow the development of Multitenant applications, on top of which a mechanism for Web interfaces customization, called MHT (Multitenant Hierarchical themes), based on the MVC pattern, on the concepts of themes and of hierarchies, was built

Motivation. The motivation for this thesis is to explore the only recently evolved cloud accounting phenomenon which in essence is doing accounting no longer within the boundaries of a business, but connected to the Cloud. Problem statement. The aim of this thesis is to examine the way in which cloud computing impacts accounting practice. Few previous studies have been conducted so businesses have not been able to understand the cloud accounting phenomenon thoroughly, preventing businesses from adopting their business models on the basis of the Cloud. This means that businesses have potentially missed out on opportunities for competitive advantages and growth. The purpose of this thesis is to understand the cloud accounting phenomenon in an in-depth manner. Approach. This thesis can be classified as empirical positive qualitative research and empirical quantitative case study which uses an explanatory and exploratory research approach. The case study was conducted in in-depth interviews and the extent of this work encompasses primarily the Swedish accounting environment. It consists of six cloud accounting users and two cloud accounting provider. Results. This study contributes four main findings to the existing field of research. Firstly, the initial adoption decision and acceptance of cloud accounting Software-as-a-Service is based on the perceived usefulness that the Cloud enhances the accounting process in terms of efficiency and effectiveness. The usage decision is voluntary to obtain a better image and status. Secondly, trust was identified as a central component within the relationship between user and provider in cloud accounting service partnerships. Thirdly, the Cloud brings the possibility not only for accountants, but for the entire business to access an unlimited amount of resources. Users can become easily dependant on a provider if they perceive the service as a crucial asset for their business. The dilemma between the trade-off between autonomy and certainty occurs. Users are aware that they need to give up their right for self-government for the benefit of attaining a cloud service, and expressed concerns in respect to privacy and security, implementation issues, legal requirements, and increased costs. Moreover, users fear that they become dependant and locked in with a cloud accounting provider. Fourthly, the Cloud brings the possibility to access an unlimited amount of resources not only for accountants, but for the whole business. Cloud providers offer their service to a broad customer base which means that the structures in different businesses may possibly become more similar.

<p>Ett CRM system ger fördelar för ett företags förmåga att bygga varaktiga kundrelationer. Små och medelstora företag är dock tveksamma till att investera i sådana system. Resurserna för att dels investera i och sedan effektivt förvalta systemen fattas ofta i företagen. Implementationerna av systemen drar dessutom ofta ut på tiden. Modellen Software as a Service har under 2000 talet vunnit stora landvinningar. Leverantörer som erbjuder CRM funktionalitet som en betald tjänst över Internet är ett attraktivt alternativ för små och medelstora företag som vill kringgå ovanstående problem. Samtidigt råder en viss tveksamhet till vilken kvalitet dessa tjänster håller. I denna studie söker vi svar på hur små och medelstora svenska företag upplever fördelarna med att köpa in ett CRM system som en SaaS tjänst.Syftet med denna studie är att kartlägga hur ett antal små och medelstora svenska företagupplever fördelarna med att köpa in ett CRM system som SaaS tjänst och presentera resultatet som en källa till kunskap om CRM system som SaaS tjänster. En kvalitativ studie har bedrivits med litteraturstudier som metod för insamling av sekundärdata och semistrukturerade telefonintervjuer som metod för primärdatainsamling. Fyra företag som använder ett CRM system som SaaS tjänst har deltagit i studien. Studien visar att fördelarna med leveransmodellen SaaS eliminerar flera potentiella hinder för små och medelstora företags förmåga att köpa in ett CRM system. Företagen undgår kostsam hårdvara och IT förvaltning. Kvalitén för dessa tjänster håller även en hög standard. Implementationen av tjänsterna upplevs av företagen som snabba och betalningsmodellen medför låga initialkostnader och ger en låg totalkostnad. Det medför även möjligheter till ett mobilt arbetssätt.</p> / Vet ej vem som är examinator för uppsatsen.

Making a communication tool easier for people to operate can have profound and positive effects on its popularity and on the users themselves. This thesis is about making it easier for people to publish web-based documents that have sound, video and text. Readily available software and hardware are employed in an attempt to achieve the goal of providing a software service that enables users to compose audio-video documents with text.

Software as a Service är en växande leveransmodell och används numera utav verksamheter världen över. Nya leveransmodeller av tjänster kräver dock nya perspektiv på hur de påverkar verksamheten. Studien baseras på en kvalitativ, intervjubaserad, undersökning mot kommuner inom Västra Götaland. Frågan som ställs, och studeras, är följande: Vilka faktorer påverkar beslut vid upphandling och implementering av ”Software as a Service”-baserade tjänster hos kommuner inom Västra Götaland?” Studien baserades på en kvalitativ metod där intervjuer användes som den främsta resursen för insamlingen av data. En litteraturstudie kompletterade intervjuerna genom att skildra tidigare forskning och det generella området. Resultatet av studien pekar på fem olika faktorer som påverkar beslut vid upphandlingen, och implementeringen, av ”Software as a Service”-baserade tjänster hos kommuner inom Västra Götaland. Dessa fem faktorer är Lagen om Offentlig Upphandling, Informationssäkerhet, Implementering, Leverantör samt Kravställning. Resultatet riktar sig till att användas som en grund för ett framtida formulerande av ett Statement of Work, som skall kunna beskriva hur dessa faktorer skall tacklas. / Software as a Service is a growing delivery/business model and is now well implemented in enterprises all over the world. With the addition of new delivery/business models, a new perspective is needed to mitigate certain risks and additional factors that may be identified with the new way of delivery/business. This study is based on a qualitative research method which uses interviews with municipalities in the region of Vastra Gotaland. The research question is as follows: Which factors have a deciding purpose in the procurement and implementation of “Software as a Service”-based services at municipalities in Vastra Gotaland? The study was based on a qualitative research where interviews was used as the main resource when collecting data. A literature study complemented the interviews as an additional resource to depict the general area around SaaS. The result of the study points towards five different factors that affects decision-making at the procurement- and implementation process of SaaS-based services at the municipalities in Vastra Gotaland. These five factors are Legal aspects of procurement within municipalities, (Lagen om Offentlig Upphandling), information security, Implementation, supplier and specification of requirements. The result is later supposed to be used as a baseline for a future formulatory of a Statement of Work, that will describe how these factors should be dealt with.

abstract: Multi-tenancy architecture (MTA) is often used in Software-as-a-Service (SaaS) and the central idea is that multiple tenant applications can be developed using compo nents stored in the SaaS infrastructure. Recently, MTA has been extended where a tenant application can have its own sub-tenants as the tenant application acts like a SaaS infrastructure. In other words, MTA is extended to STA (Sub-Tenancy Architecture ). In STA, each tenant application not only need to develop its own functionalities, but also need to prepare an infrastructure to allow its sub-tenants to develop customized applications. This dissertation formulates eight models for STA, and proposes a Variant Point based customization model to help tenants and sub tenants customize tenant and sub-tenant applications. In addition, this dissertation introduces Crowd- sourcing to become the core of STA component development life cycle. To discover fit tenant developers or components to help building and com posing new components, dynamic and static ranking models are proposed. Further, rank computation architecture is presented to deal with the case when the number of tenants and components becomes huge. At last, an experiment is performed to prove rank models and the rank computation architecture work as design. / Dissertation/Thesis / Doctoral Dissertation Computer Science 2017

Neste âmbito, empresas governamentais ainda possuem receio em hospedarem seus dados no ambiente de computação em nuvem, o que por sua vez, faz com que muitas dessas entidades utilizem um modelo de oferta de serviços tradicionais não otimizados no contexto de recursos computacionais. Devido a isso, a computação em nuvem privada surge como ambiente alternativo para hospedagem de serviços dentro da própria infraestrutura da empresa pública, suprimindo as preocupações de conformidades à segurança da informação e adequação do modelo de oferta de serviços. Com o objetivo de discutir e ampliar a literatura acerca do assunto são apresentados passos a serem utilizados para implantação de um cenário em computação em nuvem privada, como solução destes problemas em uma empresa pública de processamento de dados. Como contribuição prática, o estudo apresenta uma solução escalável com baixo investimento, uma vez que todo o cenário proposto é utilizado em ferramental de software livre, permitindo impactos positivos e valor agregado no modelo de oferta de serviços do provedor para os clientes.
