The aim of this diploma thesis is design and implementation of experimantal data network central management in convergent network technology laboratory. This diploma thesis is devided into several chapters. Management network fundamentals are described in introduction. Actually used experimental network is analyzed in the second chapter. Design and implemantion of web modular information system are presented in third part. Solution of central management network system is summarised at the end of this thesis.

This master thesis presents ZZM spol. s r.o.`s web portal of good store, which should improve availability of goods and sevices to ZZM`s customers and make a good way to evaluation of taking and runing the goods in a separate regions managing by ZZM. Project make use of PHP and MySQL technology. Application includes technology for autentization, security and session for following behaviour and obtaining information about customers. For better decision making aggregated data will be present in OLAP technology. Web portal will be independent application communicating with actual internal system of firm ZZM based on communication protocol PDK version 6.

The main topic of the thesis is problem of the security of the web application. Spheres that are likely to be vulnerable are thoroughly examined and ways of protecting the application in the area of access control, data transfer, user input, output and state keeping are suggested. Furthermore, with regard to the security, possible solutions of audit, backing up, web server security, database design and protection against spam robots are described. This project is also concerned with the analysis of requirements, detailed design and implementation of the club information system with demonstration of mentioned security solutions. The systems of members' evidence, evidence of breeding dogs and their pedigrees, publication of actions and results and the content management system of other sections of the web presentation are among others implemented within the scope of this IS. All the implementation solutions are based on HTML, CSS, JavaScript, PHP and MySQL technologies.

This Master's thesis aim is implementation of WebDAV interface for IS FIT document repository in PHP language. It concurs to term project, that has dealt with protocol WebDAV and open source WebDAV server. Thesis discuss protocol WebDAV and it's meaning and related technologies: HTTP, XML, PHP and MySQL. Then it describes studied WebDAV server, IS FIT document repository, design and implementation of it's WebDAV interface.

The aim of my thesis is to create a model of information system for internet stores support. Together with creating this model I will also analyse the possible use of new technologies such as AJAX or communication with the help of XML. The final work will consist of two applications, where first is a catalogue of products (goods) and the second is an internet store. The main application will provide services for this store.

{The diploma thesis is dealing with the present medical application extension by the means for decision support. The first part of the work is focused on the general problem of data warehouses, OLAP and the data mining. The second part attends to the very proposal and implementation of the extension in the form of the very application, which enables executing OLAP analysis upon the gathered medical data.

This work deals with topic of LAMP software bundle performance optimalization. Step by step, it tries to discover performance problems in all four parts of LAMP (in Linux, HTTP server Apache, MySQL database and PHP language interpreter). A model web application is created for these testing purposes. When a problem is found, a change in configuration files is done or a performance improving technology is applied to the corresponding part. A set of optimalization recommendations is compiled and verified on server running real web application.

This thesis is trying to find its way in extensive area of relatively new problems of E-learning. E-learning has come together with fast advancement of the Internet trying to make education more comfortable and faster and at the same time trying to lower its dependency on the human resources. A lot of a development of the online tests is still needed. However, it is important to make clear the rules of the "game" and to press for their integration. The first goal to achieve the full-value system which would be able to substitute the conventional methods of education is to find out and solve the issues of testing in general, to analyze the requirements and to create data format for the data portability, which is required because of the mutual communication between different systems. On these bases it is possible to design the database scheme and then the complete system.

The focus of this Master Thesis is creation of a tool for generation of photo galleries, both for personal presentation and as an internet portal for interested exhibitors. The software is aimed at users with no or minimal experience with creating internet applications. The UML language was used for the design, while the web part of the application was implemented with help of the PHP, mySQL, JavaScript and CSS. User interface under the win32 was realised using Microsoft Visual C#. The work is concluded by brief analysis of realistic benefits users get from using the application.

The objective of this project is to design and create internet shop offering functions, which are common and essential for this type of application. It will also offer functions, which will ensure troublefree and safe run. The base of design are UML models (ER diagram, USE CASE diagram). This models will be created for compact design of database, and structure of whole application. This shop will offer standard administrative functions, which will allow administrators to control the shop. Users will be not only offered by goods, but also will have their own account, where they will be allowed to check the history of their operations. The system will use PHP, html, JavaScript and SQL languages. It will be based on MySql database, Apache server and Rewrite modul of Apache.
