SAP HANA Platform
Uhlíř, Michal ; Volf, Tomáš (referee) ; Zendulka, Jaroslav (advisor)
Tato práce pojednává o databázi pracující v paměti nazývané SAP HANA. Detailně popisuje architekturu a nové technologie, které tato databáze využívá. V další části se zabývá porovnáním rychlosti provedení vkládání a vybírání záznamů z databáze se stávající používanou relační databází MaxDB. Pro účely tohoto testování jsem vytvořil jednoduchou aplikaci v jazyce ABAP, která umožňuje testy provádět a zobrazuje jejich výsledky. Ty jsou shrnuty v poslední kapitole a ukazují SAP HANA jako jednoznačně rychlejší ve vybírání dat, avšak srovnatelnou, či pomalejší při vkládání dat do databáze. Přínos mé práce vidím v shrnutí podstatných změn, které s sebou data uložená v paměti přináší a názorné srovnání rychlosti provedení základních typů dotazů.

IP Television
Mašek, Pavel ; Fojtová, Lucie (referee) ; Číka, Petr (advisor)
The main objective of thesis is proposal and realization programme, which can be able to receive and play up multimedia stream broadcasted from server via packet networks. Protocol for transmission multimedia data is used to join connection between server and end point. And therefore protocols which handle data transmission like RTP/RTCP, RTSP and also SDP and SAP are described in thesis. Description mentioned records isn't effected to the smallest details, but acts about acquaint with problems. Further be brief described libraries that the stand by drafting application in view as well as used application that the function as the source of transmission multimedia. Than follows proposal solving and single step description of programme design in thesis. Analysis of working programme is performed in the last part of thesis.

Application for Verification of Data Accuracy in the SAP HCM Module
Kolb, Jakub ; Očenášek, Pavel (referee) ; Bartík, Vladimír (advisor)
Main goal of this bachelors thesis is to show issue of data checking in system SAP. Since this system is extensive, it is nearly impossible to control the data manually. In this bachelor thesis I am describing particular proposals for improving the processes including their use in practice. This bachelor thesis is divided into three parts. In first part is mentioned necessary theory used for implementing application for data checking. Next I describe particular important data dividing with proposal of class and domain diagram. In last part of thesis I pay attention to realization and programming itself in programming language ABAP.

Fuzz Testing of Applications Communicating via the OData Protocol
Mjachky, Ľuboš ; Fiedor, Tomáš (referee) ; Vojnar, Tomáš (advisor)
Delivering stable and reliable software to customers is difficult. Applications are prone to errors, regardless of the experience level of the developers. Automated testing methods and tools are heavily used in all phases of development life-cycle to reduce chances of bugs escaping to the users. The goal of this thesis is to design an intelligent and automated testing tool which is able to test business applications. A mishandled action performed within such an application may cause a failure with disastrous consequences. To simulate these actions, one can use testing where test cases contain invalid or random data. This testing technique is called fuzzing or fuzz testing, and it involves providing malformed or mutated data as an input to the program. The proposed tool, namely ODfuzz, is a fuzzing tool ready to test applications communicating via the OData protocol which is a protocol built on existing HTTP and REST methodologies. ODfuzz is generating and fuzzing requests that are to be sent to the server. The requests contain mutated data that pass through various code paths and may result into an application error. ODfuzz was used to test back-end modules of modern SAP applications written in the ABAP language.

Application for Generating and Printing of Labels in the SAP System
Kalabza, Marek ; Rychlý, Marek (referee) ; Bartík, Vladimír (advisor)
The goal of this diploma thesis is the design and implementation of an application for generating and printing address labels in the SAP system. The work also explains the basic concepts of the SAP system and describes the technologies for creating print forms as SAP Adobe Form and SAP SmartForm. Lastly, it describes the solution of printing 1D and 2D barcodes and setting up the communication between the SAP system and the printer. The result of this work is an analysis of form creation, subsequent design of a solution for generating forms as address label, sheet of 21 address labels, Czech Post delivery notes, Czech Post delivery sheet and its implementation in the SAP system. The conclusion of the work is testing the created solution and proposing future improvements.

Secure Implementation of Blockchain Technology
Kovář, Adam ; Fujdiak, Radek (referee) ; Malina, Lukáš (advisor)
This thesis describes basis of blockchain technology implementation for SAP Cloud platform with emphasis to security and safety of critical data which are stored in blockchain. This diploma thesis implements letter of credit to see and control business process administration. It also compares all the possible technology modification. Thesis describes all elementary parts of software which are necessary to implement while storing data and secure integrity. This thesis also leverages ideal configuration of each programable block in implementation. Alternative configurations of possible solutions are described with pros and cons as well. Another part of diploma thesis is actual working implementation as a proof of concept to cover letter of credit. All parts of code are design to be stand alone to provide working concept for possible implementation and can source as a help to write productive code. User using this concept will be able to see whole process and create new statutes for whole letter of credit business process.
