Interface-Based Software Development
Rais, Aziz ; Pecinovský, Rudolf (advisor) ; Lacko, Branislav (referee) ; Merunka, Vojtěch (referee)
Even though there are many software development and project management methodologies available, research and practice both show that IT software development projects still fail, and that the quality of software products does not always meet customers' expectations. There might be multiple causes for such failures, but some of these reasons can be seen to influence or create others. Therefore, the larger the project is, the higher its risk of failure, especially if the teams involved work remotely (distributed and outsourced). This increase in project complexity is considered the motivation for this paper. Similarly, there are other factors that can result in a project's failure and customers' dissatisfaction regarding software quality. All such factors identified by research conducted by organizations specializing in this area are analyzed in order to identify a common root of IT project failures. Once the root causes of these failures have been identified and analyzed, the goal of the Interface based software development methodology is to solve them. The solution offered by an Interface based software development methodology is to improve understanding of software requirements and to describe these requirements with interfaces in an object-oriented way. Interface based software development will support and drive development towards service-oriented architecture (SOA) and component-based development (CBD). The goal of interface based software development is to increase software testability and maintainability and to make it more easily feasible to execute various software development processes in parallel.

Zobecnění objektově orientovaného paradigmatu zavedením morfologie objektů
Šlajchrt, Zbyněk ; Pecinovský, Rudolf (advisor) ; Merunka, Vojtěch (referee) ; Virius, Miroslav (referee)
Modeling protean objects, i.e. objects adapting their structure and behavior dynamically with respect to a changeable environment, is often challenging in traditional object-oriented languages. According to the author, the root cause of this problem lies in the class-based conceptual framework embedded in the foundation of the object-oriented para-digm. The proposed paradigm Object Morphology (OM) is greatly influenced by prototype theory developed in the field of cognitive psychology. OM abandons the notion of class and suggests, instead, that the abstractions of protean objects should be established through the construction of morph models describing the possible forms of those objects. This the-sis defines the theoretical foundations of OM, which is further used to specify the elements of prototypical object-oriented analysis. An important part of this work is also a proof-of-concept implementation of an OM framework in Scala.

Methods of Automated Model Transformations in Information System Analysis
Tůma, Jakub ; Merunka, Vojtěch (advisor) ; Toman, Prokop (referee)
This doctoral dissertation thesis has impact to holistically development extension of information systems. Thesis has impact to analytical models and its transformation methods.
This thesis is focused on models Business Process Modeling Notation (BPMN) and Business Object Relational Modeling (BORM). Model BPMN is developed since 2000. Model BORM is developed since 1993 and it is older. The thesis general target was extension of holistically development of information systems. The main target was to bridge the gap between BPMN and BORM models.
This thesis was inspired by Finite State Machine (FSM). The state of the art describes approaches to models transformation. In the analytical part the mathematical formula are used to describe transformation. This part is used to base for the implementation part. The implementation part contains transformation algorithm its description and verification on the case studies. Impact of developed transformation method is validated on the comparison with the other approaches.
The targets were aimed and documented automated transformation calculus. The impact of automated BPMN and BORM models connection using transformation method. The result is method of automated transformation from BPMN model to BORM model using algorithm. The transformation method is based on the Mealy automaton.

Banking Crime Detection using SQL
Nekorancová, Kateřina ; Merunka, Vojtěch (advisor) ; Radek, Radek (referee)
This bachelor thesis on Banking Crime Detection using SQL focuses in theoretical part on approach to databases. It describes progression of database, methods of storing data in databases according to defined rules, interrelationships between tables and normalization process. It contains approach to bank fraud, distribution of fraud, instruments to assist the detection of fraud and follow prevention of iteration whit the use of database systems.
Practical part contains proposal possible screenplay fraud uses knowledge of theoretical part. It contains sample tables containig data about clients, filed application and employers, which clients indicated in the application, and blacklist table to authentication company. Tables are linked through keys and suspicionus company are selected from tables. Company is regarded as suspicionus if it grows at the amount of application submitted. That company is verified in table blacklist.

Datawarehouse
Ragab Negm, Hussein Mohamed Abdelhaq ; Merunka, Vojtěch (advisor) ; Martin, Martin (referee)
Data is being produced by the firms in ever increasing rates and firms are finding new ways to make use of data to create business value. The generated volumes of data create the need for better and cheaper storage options that allows utilizing the data as well. Data warehouses have emerged as the most appropriate tool for this task. However, data warehouses come with significant costs both human and financial. The pool of technologies for implementing data warehouses is versatile. This project aims to provide a comparative implementation using two of the technologies, namely, Microsoft SQL Server and Apache Hadoop. The project covers the different phases of building a data warehouse; the requirements specification phase; the design phase and a compact comparison between the entity-relation and dimensional modeling design techniques and the process of building a dimensional model based on based on the application data sources; the extract-transform-load phase. The comparison is then made between the two technologies for data capacity, data loading, connectivity and querying data. The project concludes that the decision to choose between Microsoft SQL Server and Apache Hadoop is not a recommendation for one over the other but should be based on the needs, resources and the existing ecosystem. Hadoop would be the choice for bigger amounts of data, unstructured or irregular data formats, and when the licensing fees are an unaffordable cost. On the other hand, Microsoft SQL Server would make a better choice when the data is structured, the anticipated data volumes are suitable and when the rest of ecosystem is Microsoft based. Future development for this project should cover new ways to make Hadoop more efficient with smaller data volumes.
