This project starts off with giving an overview of what sensitive data is, encryption algorithms and other required knowledge for this thesis project.This is because of the aim of this thesis project, that is to find the best way to encrypt data passed through a URL with a focus on protecting sensitive data in web applications. Data sent through the URL of a web application could be sensitive data, and exposure of sensitive data can be devastating for governments, companies, and individuals. The tools and methods that are used for this thesis project are described. An overview is given of the requirements of the web application that was to be created, the development of it, implementation and comparison of encryption algorithms. After that, the results of the encryption algorithms are compared and displayed together with a prototype of the web application and its encryption. The results are then analyzed in two different sections: security of the encryptions and performance tests. With the results given we conclude which one of the encryption algorithms is the most suitable for our web application, and otherwise when encrypting data through the URL of a web application. The results show that AES has a great advantage over 3DES both in security and performance when encrypting sensitive data passed through a URL.Those results are then used to build a secure web application to help and assist a broker during an open showing. The web application is then used together with information from interested buyers so it can be easy for the broker to contact them after the showing.

The aim of the theoretical part is a summary of commonly used graphics components for developing web applications in Java. In the introduction, theoretical part contains basic principles and terms related to the topic of work. Below is an overview of components, which is based mostly on documentation most widely used frameworks for building web applications. Individual components are divided into groups and there are descriptions and alternative names for each of them. Description of each component is aimed at its appearance as well as at routine use in practice. The practical part results from the list of components and categories created in the theoretical part. The first part is a description of the framework and its fundamental principles, especially creation of components. Each category and the components identified in the theoretical part are analyzed from the perspective of their applications in the Wicket framework. In the case of non-existing components in the framework are given options and mechanisms that replace the functionality of missing components.

This work presents a comparison of several selected frameworks for developing Web applications in PHP. It includes analysis of key features and approaches of modern development frameworks which is important for understanding their functions. Brief description of each framework (CodeIgniter, Zend, Prado, Yii) precedes a thorough comparison. The comparison is based on defined criteria and examination whether and how a particular framework meets that criterion. Included commentary of implementation details of chosen properties introduces readers to the technical details of the solution. Work touches on questions of choice of an appropriate framework and presents its own evaluation of each selected framework.

Development of web applications is closely associated with testing. This master's thesis deals with the domain of testing. The goal of this thesis is to design a methodology of testing of web applications for small software company. The designed methodology results from OpenUP methodology and author's work experience. First, the theoretical part of this thesis is devoted to testing, history of testing and introduces several approaches to testing. Next, the theoretical part focuses on web applications and its specifics in light of testing. In view of the fact that the designed methodology is inspired by OpenUP methodology, this methodology including its basic principles and components is introduced in next separate chapter. The largest chapter describes the designed methodology of testing of web applications and its basic components: roles, activities and artifacts. Also errors and their lifecycles are examined. The thesis is concluded by a short muse upon the aspects of the implementation of the designed methodology in the environment of small company.

The growing intensity of competition between traders leads to harder acquisition of competitive advantage. Businesses and companies are therefore trying to get this benefit from e-commerce solutions, enabling them to serve as a presentation tool as well as a communication tool with the customers; reduce the transaction costs and facilitate the marketing of products and services. The increasing amount of firms using these solutions requires them to create them the most attractive and technologically advanced: therefore they utilize more sophisticated technologies that enable them to achieve this purpose. This work is dedicated to one of these technologies - Adobe Flash. It intends to familiarize the reader with this technology, compare it with the competing technologies and demonstrate its use in the commercial sphere on the World Wide Web. As well it should point out possible problems with application development and the possible solutions for these issues. On a realistic example it should demonstrate the inevitability of this technology, despite of growing competition. The readers who intend to create an e-commerce application should have enough information to be able to do so after reading this paper (the work does not devote to ActionScript programming in detail), or be able to choose a more suitable technology for their application. It also includes several recommendations to optimize Flash elements and applications to contribute to the most user-friendly experience.

Based on analysis of existing and potentially suitable solutions, the decision to develop a new program was made. Therefore, other chapters are devoted to the design and development of the program. The user's guide describing use of the final system is also part of this thesis.

The aim of this thesis is to create a business plan with an emphasis on verifying the viability of the business idea of a Web application promoting services for foreigners. The thesis is divided into two parts, theoretical and practical. The theoretical part describes the methods that will be applied in the practical part, mainly individual parts of the business plan. The business plan itself can be found in the practical part where market research, analysis of inputs and financial plan are considered as the fundamental chapters.

This thesis is focused on a comparison of two frameworks, built on two different platforms. The first one is a PHP-based framework Nette and the second one is Spring, developed in Java. They both are popular choices of frameworks on their respective platforms. The first part of the thesis' target is to introduce the reader to elementary ideas related to frameworks - design pattern MVC. The second part describes the Nette framework, the third is devoted to Spring framework. The fourth part deals with an example application and it's realization in both Nette and Spring, and the fifth and last part compares both frameworks, evaluates them and closes the whole topic.

The thesis is concerned with an in-depth analysis and evaluation of the JBoss RichFaces component framework with regards to its particular strengths and weaknesses.
