Transformace z OCL do SQL
Sobotka, Petr ; Richta, Karel (advisor) ; Kopecký, Michal (referee)
The aim of this Master Thesis named Transformation from OCL into SQL is to explore possibilities of enhancing Enterprise Architect by the ability of generating SQL code that implements OCL constraints of a Platform Independent Model, and to create a working prototype that demonstrates this capability. The thesis contains a brief introduction to the problem of Model Driven Architecture, why it would be useful to implement the specified constraints directly in the database, a description of the interaction with Enterprise Architect along with analysing how to get the needed data, the way OCL can be mapped onto SQL, and finally it describes the implementation of the OCLtoSQL plugin from its analysis and chosen architecture to its documentation.

Analysis and enhancements design of the business intelligence subsystem.
Buchlák, Peter ; Král, Jaroslav (advisor) ; Richta, Karel (referee)
A great number of organizations realize the need to search for and collect the data, which are very useful for obtaining the information that simplifies the key business decisions. From that reason comes it nowadays to the development in a field called Business Intelligence (BI). BI is a complement of processes, technologies and tools that enable to transform company's data to actionable business information useful for particular actions, promotion of the business decisions and improvement of the running of the company. BI combines the ideas and processes from the business world and using algorithms and techniques for managing of the data and transformation of this data into useful information. The goal of this master thesis is to extend the existing information system by BI subsystem and thereby support the decision making of management and improve company's competitive edge. There is necessary to analyze of important data and processes in company, chose the proper architecture, make a design and implementation of BI subsystem. The main output of this work is the prototype implementation of BI subsystem named UESBI which will be sequentially deployed and progressively extend by additional functions.

Methodology for Effort Estimation of Software Development Process
Cipra, Jan ; Richta, Karel (advisor) ; Král, Jaroslav (referee)
The work deals with software projects estimation. The first part presents selected methods for estimating and associated problems. Next there is an analysis of the estimation and the choice of methods suitable for use in the Komerční banka. In the second part of the work, there is proposed a methodology for estimating the size of software projects and the work needed for their completion. This methodology is not intended only for the software development in the Komerční banka, with whose cooperation the work was created, but it is with minor changes sufficiently universal and applicable in other companies. Part of this work is also a simple tool designed to support the estimation using the methods of the proposed methodology.

Comparation of Software Process Maturity Level of Enterprises in Czech Republic
Borský, Miroslav ; Richta, Karel (advisor) ; Král, Josef (referee)
There are many software developing companies in the Czech republic. However the quality of their software processes is almost unknown. The thesis provides insight into the maturity level of the software processes and finds a relation between the maturity level and a size of the company. The survey of the maturity level was performed at fifteen companies developing the financial software. Additionally, a bank and a foreign company teams were chosen for a comparison. Collected data were represented in a graphical format and a description was provided. A correlation between a size of a company and the maturity level rating have been detected at five out of eighteen process areas and at two out of four process area groups. A possible explanation for those correlations was offered.

Graphical Environment for the Design of Dialog Based Applications
Živčák, Imrich ; Richta, Karel (advisor) ; Píše, Michal (referee)
State machines are commonly used in Software engineering during software design and development. Today's well-known UML language forms basic resource for representation of state machines. However, they didn't have an XML representation till now. Emerging standard for State Chart XML (SCXML) language brings new possibilities for representation and also interpretation of state machines. This thesis focuses on analysis of present SCXML language draft. It compares SCXML language possibilities with grafical representation of UML languge and searches for draft defects. At the same time it proposes new graphical representation matching language possibilities, and implements it in a grafic tool. Created tool consequently provides support for design of dialog based applications. Dialog can be represented just right by a state machine.

Tools for NDL Elaboration
Myazina, Elena ; Richta, Karel (advisor) ; Kopecký, Michal (referee)
Title: Tools for NDL Elaboration Author: Bc. Elena Myazina Department: Department of Software Engineering Supervisor of the master thesis: doc. Ing. Karel Richta, CSc., Dept. of Software Engineering, Faculty of Mathematics and Physics, Charles University in Prague Abstract: Current state of research of networks enables end users to create custom connections (lightpaths) for a given application and optical private networks (OPNs). Such adjustments require clear communication between the requesting application and the desired network. Language NDL (Network Description Language) is used to describe such optical networks. NDL is based on the Resource Description Framework (RDF). This thesis analyzes the network description language NDL and its treatment. Current status of the network can be loaded in the form of the description in the NDL and displayed as the graphical representation. The representation enables to find out paths in the network, or edit the network. The result can then be transformed back into NDL format. Keywords: NDL, RDF, optical technology.

Querying relational databases through XSLT
Mareš, Jiří ; Pokorný, Jaroslav (advisor) ; Richta, Karel (referee)
XML is becoming standard for information representing and data interchange. A question has arisen if it would be possible to combine simplicity and user friendliness of XML and its querying languages together with performance of relational databases, has arisen. There are several proposals how to carry this connection out. The aim of this thesis is to inspect one of these proposals, eventually modify it and then implement it. The inspected proposal stores XML data into relational database based on knowledge of XML DTD and subsequently queries them using XSLT. XSLT queries will be transformed to SQL queries using DTD of XML data stored in database and a way to transform data back to XML will be suggested.

Support for fundamental component development scenarios
Milata, Tomáš ; Bureš, Tomáš (advisor) ; Richta, Karel (referee)
A problem of component systems is complexity of the development process causing high complexity of supporting tools. This thesis defines a subset of basic development scenarios in SOFA 2 component system such that it results in a complete application and covers all basic concepts of SOFA 2. The individual scenarios are described in context of SOFA 2 IDE and are analyzed for the purpose of determining problematic points, which are points hard to understand for novices and tasks that developers are forced to perform in a lengthy way because of the tools. The thesis presents, as an answer to the issues, a SOFA 2 Guide set of software tools capable of generating certain content of entites and Java source code. Alongside, it uses the Cheat Sheet tool as an interactive navigation through the development cycle. The solution contributes to simplification of SOFA 2 learning process and to speeding up the development. A possibility to add a guide to more advanced SOFA 2 topics or C/C++ code generator suggests itself for future extensions.

Conceptual Modeling of Business Artifacts and their Implementation as Active XML
Poljak, Štěpán ; Nečaský, Martin (advisor) ; Richta, Karel (referee)
In the present work we study conceptual modeling of business ar- tifacts and their implementation in Active XML. Business artifacts are key con- ceptual entities of business processes that develop in their lifecycle during these processes. There are several possible methods for definition of artifact lifecycles. In this work, we make use of emerging method called Guard-Stage-Milestone meta- model and we study the question on how to appropriately use and extend current framework for conceptual modeling of XML schemas in order to support modeling of business artifacts. We also deal with the issue of design of suitable represen- tation of business artifacts using Active XML. Last but not least, we study the question how to translate defined model into proposed Active XML representation, so that it was possible to immediately use and demonstrate functionality of defined model. Important part of this work is an implementation of proposed extension and a prototype implementation of system for execution of Active XML repre- sentations of translated models. The present work also introduces the reader in individual used concepts and describes similar existing approach for Active XML representation of business artifacts. 1

Using business process modeling tools for development of formalized medical guidelines
Mišúr, Juraj ; Nagy, Miroslav (advisor) ; Richta, Karel (referee)
This thesis is analyzing the usage of business process modeling (BPM) tools in the eld of medical guidelines. Business Process Management Notation is used for business process modeling and a sample medical guideline from the eld of cardiology is modeled with it. This guideline is then converted to Business Process Execution Language and executed in runtime environment to simulate the guideline behavior. Learned facts are then used to compare BPMN and BPEL with the existing modeling language for medical guidelines - GLIF. The practical result of this thesis is a prototype application evaluating medical guidelines modeled using BPMN and executed using BPEL. The guideline also communicates with electronic health record for gathering patient's data.
