Design of the database for courier company
Kolman, Michal ; Palovská, Helena (advisor) ; Tomášková, Barbora (referee)
This bachelor thesis deals with the analysis of requirements and design of database for a courier company engaged in food delivery services. The aim of this thesis is to create a database design that would be used for an application enabling dealing with orders and registration of subjects that have access to them. The the-sis is divided into two parts. The first part is devoted to theoretical basis, explanation of important database concepts and how to design a database. The second part deals with the design of the database. I proceeded from the analysis of the courier company across con-ceptual and physical database design to verification of the database with simple commands on the school Oracle database server. The assumed contribution should be an option for employees to track the status of the or-der. The management of the company will have all the information about orders and finan-cial transactions registrated in one place and be able to analyse all the information. Customers should have an easy overview of their benefit program, possibly also of their credit system. Couriers and operators should have an easy overview of cash transactions and the current financial situation of the couriers. On that basis, they should be able to quickly allocate the orders.

NoSQL databases- IndexedDB
Vršek, David ; Palovská, Helena (advisor) ; Tomášková, Barbora (referee)
The thesis provides introduction to IndexedDB, describes its specificity and aims at security analysis of IndexedDB. The thesis focuses on extension of IndexedDB knowledge and description of technologies, concepts and environment connected with it. A part of the thesis is a practical example showing how to work with IndexedDB followed by a security analysis illustrating a secure way of IndexedDB usage. The main benefit of the thesis is extending knowledge of IndexDB's concepts shown in a big picture supported with a practical example. The big-picture point of view allows the thesis to make the reader think differently regarding security and development while using IndexedDB. The thesis also illustrates the differences between IndexedDB and the rest of NoSQL products through practical and theoretical part as well. The introduction briefly explains NoSQL concept with a short description of the differences from the standard. These differences come from the connection of IndexedDB, HTML in version 5 and JavaScript, in version EcmaScript 5, which is the current standard for JavaScript. These technologies and other concepts will be described in context of IndexedDB. The next part of the thesis shows how to work with IndexedDB on practical example. This part is followed by a security analysis. The thesis can be used for advanced technological analysis of explained security issues.

Methodology of development and maintanance of dependent data marts
Müllerová, Sandra ; Novotný, Ota (advisor) ; Tomášková, Barbora (referee)
The thesis is primary focused on the integrated data warehouse, particularly on a subset -- dependent data marts. The main objectives of this thesis are design the methodology of development and maintenance of dependent data marts and verification methodology usefulness in the real organization. The first part deals with the theoretical definition of terms. It focuses particularly on the definition of terms from Business Intelligence area especially data warehousing and data marts. Each of the terms is described in detail in separate chapters. Business Intelligence area puts emphasis on description of individual components. In data warehousing area are described the data warehouse concepts and content of layers in a data warehouse. Finally, the data mart area is designed to describe dependent and independent data marts and also "special "cases of data marts, likely the semantic layer, and a sandbox. The second part focuses on the design methodology itself. At the beginning of this part is analysis of the existing methodologies and assess their usefulness with connection to designed methodology. The following part describes the current situation in the approach to the development and maintenance of dependent data marts in the organization. At the end of the second part is designed own methodology, which is based in part on the analysis methodology and in part on the analysis of current situation. The third part focuses on usability and usefulness evaluation of methodology in the organization. Evaluation is based on the methodology of criticism from employees in the organization who are directly engaged in designing and maintaining dependent data marts. Finally, the fourth and final part will focus on the description of an alternative solution that could be considered as one of the ways to sustainable development of data warehouse in the organization. It's about comparison architecture based on utilization of semantic layer as oppose to the "three layers" concept of data warehouse by Bill Inmon, which is implemented in the organization. The output evaluates alternative solutions to the current solution.
