<p>This thesis will look into what kind of solutions a company or a private person can use if they want to create a dynamic website using only free software. To do this we divided our work in two parts. In the first part, we developed a dynamic website for a Swedish company. On the server side we used exclusively free software with open source code. There are different meanings in how the term “free” should be used when referring to software, which we will explain in the thesis. We have also chosen to work with the XMLtechnology to see if it lives up to its expectations and to see if we could benefit from the technology. Alongside with the development of our site, another company developed a site for the same company as us, by using non-free software. We have described both implementations and compared them to see if it is possible to do the same thing with both free and non-free software. </p><p>The investigating part of our work consisted of getting information about what other people think about the free software phenomenon. To do so we created an online questionnaire where we randomly picked 100 Swedish web agencies and asked them to answer 8 questions about what kind of software they used in their company, and what they thought about free software. To get some more opinions we also interviewed two persons involved in these kinds of topics. Jan Sandred, who is a well known expert advisor in topics concerning the Information Technology area and Richard Stallman, the founder of GNU and the Free Software Movement. </p><p>The reason for dividing the thesis in two parts was to get an overall picture on the subject. We did not only want to base our results on other people’s thoughts. We wanted to make our own conclusions based on the implementation we did. This approach showed out to be very good. We got to try working with free software ourselves to see its pros and cons and build our own opinions about it. We could then proceed to compare our impressions to other people’s impressions about free software.</p>

The promise of service oriented computing, and the availability of Web services promote the delivery and creation of new services based on existing services, in order to meet new demands and new markets. As Web and internet based services move into Clouds, inter-dependency of services and their complexity will increase substantially. There are standards and frameworks for specifying and composing Web Services based on functional properties. However, mechanisms to individually address non-functional properties of services and their compositions have not been well established. Furthermore, the Cloud ontology depicts service layers from a high-level, such as Application and Software, to a low-level, such as Infrastructure and Platform. Each component that resides in one layer can be useful to another layer as a service. It hints at the amount of complexity resulting from not only horizontal but also vertical integrations in building and deploying a composite service. To meet the requirements and facilitate using Web services, we first propose a WSDL extension to permit specification of non-functional or Quality of Service (QoS) properties. On top of the foundation, the QoS-aware framework is established to adapt publicly available tools for Web services, augmented by ontology management tools, along with tools for performance modeling to exemplify how the non-functional properties such as response time, throughput, or utilization of services can be addressed in the service acquisition and composition process. To facilitate Web service composition standards, in this work we extended the framework with additional qualitative information to the service descriptions using Business Process Execution Language (BPEL). Engineers can use BPEL to explore design options, and have the QoS properties analyzed for the composite service. The main issue in our research is performance evaluation in software system and engineering. We researched the Web service computation as the first half of this dissertation, and performance antipattern detection and elimination in the second part. Performance analysis of software system is complex due to large number of components and the interactions among them. Without the knowledge of experienced experts, it is difficult to diagnose performance anomalies and attempt to pinpoint the root causes of the problems. Software performance antipatterns are similar to design patterns in that they provide what to avoid and how to fix performance problems when they appear. Although the idea of applying antipatterns is promising, there are gaps in matching the symptoms and generating feedback solution for redesign. In this work, we analyze performance antipatterns to extract detectable features, influential factors, and resource involvements so that we can lay the foundation to detect their presence. We propose system abstract layering model and suggestive profiling methods for performance antipattern detection and elimination. Solutions proposed can be used during the refactoring phase, and can be included in the software development life cycle. Proposed tools and utilities are implemented and their use is demonstrated with RUBiS benchmark.

<p>Web service is a sophisticated SOA technology with a lot of infrastructure. In this thesis we will get to understand the core aspects and advance futures of Web services and get a solution based on Sauer-Danfoss’s requirements. The critical requirement include to find appropriate Web services application server, to realize an automatic update process and to get a general overview of Web services technology. The challenges in this thesis is obviously in getting understand Web services architecture and programming in unfamiliar language using chosen Web services framework.</p>

<p>Paramount Salt Handicraft A wholesale Himalayan salt company was previously doing business in traditional way and was limited only to the local market. However from the start day management was planning to expand the business to more locations and to attract more customers. So to expand the business and to attract the international customers and customers from other cities of Sweden it was necessary to make it available over the internet so that customers can easily get knowledge about the company’s products and purchase them. So the need of an online web shop was realized to bring the company’s plan into reality. The online shop will be act as a medium of interaction between the customers and the company and it will enable the customers to buy products online and make payments electronically and after that the products will delivered to them. Throughout the process the customers can easily track the overall status of their orders.</p>

Personalization in online services is the practice of tailoring data contents for customers according to what is supposed to be their expectation. By design, personalization has been considered an important tool to help users to find the most interesting relevant data. By doing that, personalization also filters the web contents and potentially narrows the view of users. In this context, our work aims to measure personalization levels of web search results. First, we study personalization for web search engines with two case studies about Google Search. The results show a remarkable level of Google personalized search results based on sets of keywords, and we show that a specific website appears as prevalent in the results of web searches. Second, we measure the personalization degrees of an online news aggregator to provide a wider view of the problems. It also shows that compelling evidence such as “suggested for you" heavily depends on past users’ activities. Finally, we study personalization of search results on an online shopping platformby measuring price steering phenomenon. Particularly, we investigate the impacts of online behaviours, locations and economic performance factors, and we observe that price steering is based on user’s behaviours but it is also influenced by the geographic location of users.

The fundamentals of software testing and related activities are often elusive in undergraduate curricula. A direct consequence of the lack of software testing efforts during education is the huge losses suffered by the software industry when applications are not sufficiently tested. Software practitioners have exhorted faculty members and institutions to teach more software testing in universities. The purpose of this research is to provide answers to the needs of such practitioners and introduce software-testing activities throughout the curriculum. The most important goal is to introduce software-testing education without requiring a significant amount of extra effort on behalf of faculty members or teaching assistants. The approach taken comprises the development of the Web-based Center for Automated Testing (Web-CAT) and the introduction of test-driven development (TDD) in courses. Web-CAT serves as a learning environment for software testing tasks and helps automatically assess student assignments. A comparison of student programs developed using Web-CAT with historical records indicated a significant decrease in the number of bugs in submitted programs. Undergraduate students also received exposure to the principles of software testing and were able to write test cases that were on an average better than those generated by an automated test case generator designed specifically for the assignment.<br>Master of Science
