Scripting engine in .NET
KARDA, Ladislav
The target of this work is to introduce scripting as a whole including its possibilities and to create a class, which permits scripting; it means modification of source code of the script and its execution in malicious code-safe environment. .NET environment and Boo scripting language are accentuated here. In the second chapter, there is the introduction itself. Scripts are divided into categories according to their usability. This division is just a general one because some languages may belong to more than one group. Every language is briefly described. The last subchapter is dedicated to Boo programming language which was chosen for application in .NET. The third chapter familiarizes the reader with the Microsoft .NET technology. Advantages and principles of its behaviour are listed here. There are mentioned Common Language Infrastructure, Common Language Runtime and Common Intermediate Language. There is a characteristic of the development environment for .NET languages. The fourth chapter deals with practical realization of the selected task; it means creation of the scripting class. The first part of this chapter defines some specifications of the Boo language and the other part pursues to explanation of the class creation. The main stress is on security against malicious code. In the appendices, there is a listing of a source code of the Booish class {--} an interactive interpreter of the Boo language {--} and the ScriptHost class which ensures right and safe fulfilment of the script in C# and/or Boo languages. The ScriptHost class can be used even outside the GREG project; it is possible to use it everywhere where you need dynamical language processing {--} C# or Boo.

Using of Information and Communication Technologies in the course of analysis of capital markets
Polsemov, Anton ; Bruckner, Tomáš (advisor) ; Chocholatý, Drahomír (referee)
This graduation thesis is exploring using of Information and Communication Technologies in the course of analysis of capital markets. The basic financial theory is described at the begging of the thesis. After this we investigate information dilemmas. Expansion of information science allowed modern stock exchanges to change their traditional trading model to electronically trading model, which is much cheaper and faster. Stock exchange trading systems, clearing centers, depositors of securities and trading platforms are described in this thesis. These technologies allow us to automate a process of trading. Nowadays the modern stock exchange is a provider of high-quality IT services. In addition, IT offers a number of tools for analysis of capital markets. These tools are applications for technical and fundamental analyses. Stock screeners allowed us to filter a big set of securities. It is the most usable analysis technology. In the last section of the thesis the technical stock screener which allowed identifying market opportunities was created. We used Microsoft Visual Studio 2008 and C# the programming language. We found a volume indicator which allowed us to achieve above-average gain 5% during the analysis of the big set of market data.

Object-relational mapping on .NET
Popelka, Aleš ; Pavlíčková, Jarmila (advisor) ; Machač, Ivo (referee)
This study concerns the theme of object-relational mapping on the .NET platform. It briefly explains the differences in the relational and object view on data a therefore it describes design patterns which are in object-relational mapping vastly applied. These design patterns are described in order to inform the reader about their advantages as also disadvantages and they are commonly depicted with an elementary illustration. The description of the design patterns is followed with a specification of the .NET framework and other elements (e.g Visual Studio 2008), which are essential to define for further progress in this study. The specification concludes into description of four products, which serve as modelers and generators of the object-relational mapping layer. The goal of this study is to provide a view of the object-relational impedance mismatch issue, means of its solution to the reader and help him with eventual need to invest into products which aid in object-relational mapping on .NET. For potential need to invest in other products than those which are tested in this study is the reader supplied with well-formed rating criteria which are, in my opinion, ready for being standardised. These goals are achieved by generating the mapping layer with all four tested products and description of the mapping process and the layer afterwards.

Framework for teaching Database Management Systems on VŠE Praha
Turčín, Pavel ; Chlapek, Dušan (advisor) ; Palovská, Helena (referee)
This thesis focuses on design and subsequent realization of e-learning support for the database management systems course. The first step is definition of the e-learning itself as well as other related concepts. Following part analyzes current status of teaching and evaluating students' knowledge and other possible ways to do so without changing the basic course frame defined by the given syllabus. A list of requirements on the software framework is made on basis of this analysis. These requirements are technical (demanded functionality) and economical (costs of installation and maintenance). The most suitable e-learning system is chosen according to these requirements. The chosen system unfortunately does not fulfill all specified requirements and software witch does, is not available. In this case the following step is design and realization of such software. At first are all requirements specified in detail. The software solution is designed as three independently usable applications: Exercise client, Test client and Administrator. Software is implemented in C# programming language. Whole process of implementation is divided into three increments witch corresponds with projected applications. Every increment adds new functionality to existing solution and the output of every increment is fully usable component.

Use of LINQ technology
Fexa, Marek ; Buchalcevová, Alena (advisor) ; Jelínek, Pavel (referee)
This work is focused at new Microsoft technology for querying data LINQ (Language intergrated query). It is built as complex technology, it allows working with various data sources. For example it contains collections of objects, created for temporary storing data in memory, but also data in robust database systems. In first part of this work I describe how data was queried before LINQ was on scene and what reasons made LINQ originate. Then I analyze new features in C# that were prerequisites for creating language integrated query as part of base libraries. Next part focuses at query operators, their interfaces and provides examples of use. Then I describe LINQ technology in complex, I create and describe in detail process of execution of LINQ query. Next chapter describes querying ADO.NET Datasets. Practical examples are created for both typed and untyped Datasets. In following chapter I analyze LINQ to SQL functionality. There is described method of implementation, mainly translation LINQ query to SQL language, integrated object rational mapping tool, change tracking in mapped objects including concurrency problems. At the end of the chapter I sketch the future in data access in ADO.NET entities. In last but one chapter is created complex application of use LINQ technology. Application is built as thin client that uses LINQ as for reading and manipulating data from relational database. In the application is LINQ also used common work with component that presents data. At the end part of this work is LINQ technology summarized. Contribution and pitfalls of LINQ technology are also described.

Využití objektových technologií při vývoji webových aplikací
Miškovský, Václav ; Brabec, Tomáš (advisor) ; Holiš, Radek (referee)
Cílem této práce je poskytnout souhrnný pohled na technologii .NET, především s ohledem na objektově orientovaný přístup k tvorbě webových aplikací, který s sebou přináší, a zároveň v kontextu ostatních (starších i současných) technologií vývoje webových aplikací. Práce je rozčleněna do 4 částí. První část popisuje principy objektově orientovaného přístupu a definuje webovou aplikaci tak, jak bude dále chápána v textu. Dále se zabývá vývojem v implementaci webových aplikací a stručně popisuje hlavní nástroje, které se k tomuto vývoji vážou. Druhá (hlavní) část se v úvodu věnuje novým a inovovaným technologiím vývoje webových aplikací a potom se zaměřuje konkrétně na technologii .NET, která je hlavní náplní této práce. Ve třetí (praktické) části jsou na příkladech ukázána řešení typických problémů tvorby webových aplikací (v .NETu a PHP). V závěru jsou zmíněny výhody objektového přístupu při vývoji nejen webových aplikací, sumarizovány poznatky a náměty pro další práci.
