Prototype for specialized business intelligence in merchandising
Jakab, Gergely ; Mrázová, Iveta (referee) ; Král, Jaroslav (advisor)
One of the purposes of merchandising is to place the correct product to the correct place with the correct price and at the right time. This thesis analyses the possibilities for automation of the process of product placement in racks of retail stores to help the merchandiser's work. The solution uses statistical data from sales to evaluate the products in order to choose the best sellers, then it suggests a suitable placement for the chosen products. Based on the results of the general analysis part a system is designed for automation of the process as an extension to an existing software. According to the created design a prototype is implemented.

Analysis and enhancements design of the business intelligence subsystem.
Buchlák, Peter ; Richta, Karel (referee) ; Král, Jaroslav (advisor)
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.

Reverse engineering on AS/400 platform
Imrich, Tomáš ; Král, Jaroslav (referee) ; Bednárek, David (advisor)
Application System/400 (AS/400) is a minicomputer designed and made by IBM. It's an object-based system with an integrated DB2 database. AS/400 used to be a popular platform for backbone systems with high requirements on stability. Considering the time when these systems were made, the programming language most often used was COBOL in addition to an in-built scripting language CL (Control Language). Companies using systems on the AS/400 platform often encounter complications during further development of these systems due to insufficient documentation of old programs. The solution for these companies is to have a tool which will generate documentation by means of reverse engineering of the system. This is a "low-level" documentation describing all components of the system, their interconnection and use of resources, and it gives a global view of how the system is implemented. The aim of the thesis was to design a form of such documentation and to analyse possibilities of its automated generating with use of reverse engineering. Based on this analysis a tool was implemented which is able to produce a documentation for a general system written in COBOL and CL (Control Language), using the integrated DB2 database.

The standard SOAP and its applications in small and middle enterprises.
Lupták, Boris ; Král, Jaroslav (advisor) ; Bulej, Lubomír (referee)
SOAP standard is core protocol used in web services. Web services open new possibilities in application interaction over the network. In connection with web services there has been much discussion of service oriented architecture. The main goal of this thesis is to show possibilities of SOAP in the context of small and medium businesses. To achieve this goal SOAP and accompanying nonns are described as well as the mechanism through which SOAP can be and is extended. Several standard extensions are shown. Furthennore this thesis points out the pros and cons of such usage as well as similar alternative approaches. The usage of SOAP is docmnented on several real life exainples. Part of this thesis concerns with fundamental principles of service oriented architecture and the connection between web services and service oriented architecture. The need of web services alignment with business processes and coarse grained interfaces are discussed as well. Powered by TCPDF (www.tcpdf.org)

Bussiness intelligence means in modern information systems
Vojtek, Martin ; Richta, Karel (referee) ; Král, Jaroslav (advisor)
Business intelligence (BI) is the ability to find and understand complex relations in business, to effectively adapt to changes of environment (competition, market, trends), to learn from data. Integration of BI applications with existing enterprise information systems leads to complex process. This process can comprise information, process, portal and service oriented integration. For this type of integration, it is also possible to use ESB technology. When integrating such complex systems, usage of standards gains great importance and significantly contributes to the architecture of result solution. Implementation of integration of BI applications with enterprise information systems represents the EPA application, which is built on Java EE integration platform with usage of JBosss, open source application server, Oracle database, data mining tools and ETL. Data warehouse implemented on the top of Oracle database is used for the integration of data sources. Part of the application presenting graphs and interactive cross tables is built on JBoss Seam, modern integration framework, which integrates technologies like JBoss Rules, JSF, EJB3 and jBPM.

System Integration using Common Domain Model
Choma, Martin ; Král, Jaroslav (referee) ; Richta, Karel (advisor)
Canonical Data Model contains description of all data used by organization. Such "all-covering" model is difficult to create and therefore it is preferred to define CDM as data model used by messages and events of integration purpose. Using CDM is not simple. First of all it is necessary to define own canonical data model. Typically, CDM is created in some CASE tool and described by some modeling language, e.g. UML. Next issue is mappings and transformation between CDM and application formats. Work lists some kinds of transformations, which can be used, possible implementations and locations of them. Finally work describes change and release management process, which is key part of CDM successful story. CDM change can affect all integrated applications, therefore is important to be ready for this situation and think about deployment process, especially when there are incompatible changes.

Means simplifying data entry in large ERPbased on SAP framework
Gold, Otto ; Richta, Karel (referee) ; Král, Jaroslav (advisor)
The thesis deals with the problem how are the various information system user interfaces suitable for the various groups of users of the IS. The author examines the impact of using suitable or unsuitable user interface on data entry process effectiveness in the scale of large IS. The thesis studies the user demands on IS and its interfaces and how well the interfaces solve these users demands. Author of the thesis suggests the measurement of the relationship quality between the users and the interface and using the exact method of search for the deficiencies in this relationship. The eforms technology is used to demonstrate that the new-fashioned and innovative user interfaces exists and can solve some users demands in the appropriate manner.

Bulk Evaluation of User-Defined Functions in XQuery
Bednárek, David ; Král, Jaroslav (advisor) ; Kuznetsov, Sergey (referee) ; Krátký, Michal (referee)
XPath queries are usually translated into an algebra that combines traditional relational operators and XML-speciffic ones. In particular, FLWOR loops are represented using nest, unnest, join, and similar operators and their original nested-loop nature disappears, creating an opportunity for bulk evaluation and join reordering. In XQuery, two additional issues shall be handled - tree construction and the presence of user-deffined functions. The recursive nature of functions pushes the problem outside of the range of relational algebra. This thesis presents a novel evaluation framework based on an expanding network of relational operators, called R-program. In this environment, functions are evaluated in bulk instead of evaluating each call separately. Besides obvious advantages of bulk evaluation, R-programs also allow rearrangement of data flow across function boundaries. A set of program transformations employing these capabilities is described; together with rule-based static interprocedural analysis algorithms used to determine the applicability of the transformations.

Tools for experiments with grammar and languages
Krejsa, Jiří ; Král, Jaroslav (referee) ; Bednárek, David (advisor)
The main goal of the thesis is the design and implementation environment that provides tools for working with grammars and languages. The environment is implemented by the library to which the user is working through the API. The library enables manipulation with languages represented as grammars or automata, transfer language between its various representations and to test whether the grammar is regular, linear or LR(k). The library found counterexamples in case that condition is violated. The thesis also highlights the future library expansion. Part of this work is a sample implementation of library usage. The library and samples are written in C++.
