Transformation of Web Applications into Web Services
Zámečník, Miroslav ; Rychlý, Marek (referee) ; Weiss, Petr (advisor)
Present web is aiming to the possibility of automatization of user behavior on web applications. Adding of semantics and creation of web service interface are the main approaches for accomplishment of this user comfort. Nevertheless, this direction brings some problems which can make more difficult publishing and implementation of web documents. Web services can connect heterogeneous systems, because they are based on XML markup language that is a place where all applications can meet without lost of platform independence. The automatic transformation of a web application into a web service could be considerably more effective than to create a web service from the beginning. However, this step is for some applications almost unreal without knowledge of their inner structure. In most cases, the transformation will be done semiautomatically with help of human decisions.

Monitoring system for applications and system of linux servers
Janovský, Martin ; Chmelař, Milan (referee) ; Janovič, Filip (advisor)
Bachelor's thesis solve the problem sight above distant Linux's servers. She describes technology, that are used for following servers. Further is described application by herself. Main problem at distant sight is, that the oneself have to check every one server separately. This performs central server provided by web server with the support language PHP and database MySQL. Central server creates interface between user and servers. All application is built on PHP, MySQL and SOAP messages. Server, which is monitored, is equipped web server and application for automatic execute process. All application is then built on exchange SOAP messages, which contain monitoring information. These data are preserved in database and further used for various statistics and graphs. By the help of web interface on central server can be information suitable displayed. This interface makes it possible to do action above single processes. Restarted or stopping process is at distant management used frequently. Naturally is respect emphasis on safeness. Optimal place for placement these application is operator centre or administrator's computer. Demand user has then displayed all monitored servers on monitor. On nonstandard state of process user is promptly alert. This situation he can promptly solve.

Integration of programs into WCF web service
Chladík, Jan ; Gála, Libor (advisor) ; Horník, Jan (referee)
This thesis deals with integration of separate .NET programs of photovoltaic power plant monitoring system. The main goal is integration of functions provided by programs into a single communication interface in the form of SOAP and REST compatible web service while minimizing cost. The integration is performed using a newly developed integration application that dynamically generates a web service using WCF technology. The thesis is divided into three main parts. The first part describes the current state of the photovoltaic power plant monitoring system, its problems and solution conditions. According to these problems and conditions is designed the target state of the system. The second part is divided into phases of the project according to the OpenUP methodology. Inception phase contains a selection of technologies and approaches that are used to achieve the target state of the system in compliance with solution conditions. Elaboration phase describes how to design and define the necessary tasks of development and implementation. In construction phase is described development and implementation of tasks of designed solution within integration application including object type serialization. Transition phase describes the individual tasks of editing existing programs to achieve integration. The last part of this thesis describes some possible directions for further development of the solution. The contribution of this thesis consists in the comprehensive elaboration of all main tasks of integration of programs.

Analysis of enterprise content management in SSČS a.s. and its optimization design
Lokaj, Lukáš ; Kunstová, Renáta (advisor) ; Procházka, Rudolf (referee)
This thesis focuses on design of document exchange solution used between Stavební spořitelna České spořitelny a.s. (SSČS) and its external sales network, which is outdated and doesn't meet the needs of SSČS or sales network. The thesis also includes the identification of suitable basic principles used in the service-oriented architecture (SOA) concept and their application in design solutions. The aim of the thesis is a conceptual solution design, based on the principles of SOA and the following technological design of changes in existing environment, so that on this basis could be created a functional and technical specification for suppliers of these applications. Stated objective is achieved through an initial analysis of the current environment, which identifies the possibilities of existing applications, and identifies weaknesses in the process that will be changed in the new solution. The analysis covers as the environment of external sales network as the related environment in SSČS, which together figure in the process of documentation exchange. As the results of the analysis and based on theoretical knowledge and consultation with experts in the field of SOA is then formulated a proposed solution at the conceptual level, which is further elaborated in the description of the proposed changes in individual components of the new solution. The outputs of this thesis will serve SSČS both in terms of describing the existing and the new environment, and as an input for the specifications of the proposed amendments to the supplier concerned applications. Structure of the thesis consists of introduction, devoted to the characterization of SSČS and providing an initial framework for solved domain. This is followed by a description and the analysis of external sales network, particularly in terms of application equipment and communication flows, followed by a description of the environment in SSČS, which contains the components processing sent documents. Next part of thesis is devoted to the formulation of the basic concepts of SOA and selection of appropriate principles that are followed in the subsequent section to draft the solution itself, first at the conceptual level, followed by a detailed description of the necessary changes. Everything is then evaluated in the final part.
