Distributed Document Server Based on CouchDB Database
Kanis, Martin ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
Thesis discusses distributed database systems and its advantages and disadvantages. Further, text informs about document database CouchDB, storage of documents, synchronization and CAP theorem. The aim of the thesis is to implement distributed document management system and workflow management system based on CouchDB. The system contains a cluster with three CouchDB nodes with HAProxy in front, which does load balancing. The system allows creation of any document based on the template, manages its life cycle and workflow. It is also possible to create a custom workflow using BRMS rules. The implemented solution simplifies document management and workflow and allows a high degree of customization for the organizations needs.

Comparison of CouchDB and MarkLogic databases
Sapegina, Evgeniya ; Palovská, Helena (advisor) ; Chlapek, Dušan (referee)
This bachelor work deals with the NoSQL concepts and database management system CouchDB and MarkLogic in particular. The aim of this work is to bring the causes of NoSQL DBMS, describe their selected properties and to provide generally accepted classification of these DBMS based on their data model. Another aim is to describe the basic principles of DBMS CouchDB and MarkLogic, on selected use cases demonstrate some reasons of choosing these databases to some companies, and then compare these two DBMS and draw attention to some important aspects that may be crucial in decision making to deploy some of these DBMS. For the contribution of this work I consider compared popular and interesting because of its properties DBMS CouchDB and MarkLogic and thus created the basis for the selection of one of two DBMS into a specific project. The work is divided into four chapters. The theoretical part is introduced by the second and third chapters. The second chapter devotes to properties of NoSQL DBMS. The third chapter discusses the characteristics of DBMS CouchDB and MarkLogic. The practical part is introduced by the fourth chapter, where both these systems are compared according to various aspects.

NoSQL databases
Günzl, Richard ; Palovská, Helena (advisor) ; Strossa, Petr (referee)
This thesis deals with database systems referred to as NoSQL databases. In the second chapter, I explain basic terms and the theory of database systems. A short explanation is dedicated to database systems based on the relational data model and the SQL standardized query language. Chapter Three explains the concept and history of the NoSQL databases, and also presents database models, major features and the use of NoSQL databases in comparison with traditional database systems. In the fourth chapter I focus on the various representatives of NoSQL databases, in particular the ones that are most frequently used. In the next chapter, I have taken a practical look at a NoSQL database, specifically Apache Cassandra. I briefly describe the steps required to launch Apache Cassandra and its administration tools. In this practically-oriented chapter, I also show basic operations performed over a sample database using Cassandra CLI, its interactive command line interface. The purpose of this chapter is to make the reader familiar with the method of working with the Apache Cassandra database system and to point out some of its specific aspects. The primary objective of this thesis is to acquaint readers with the most important features and representatives of NoSQL databases and the potential for their practical use.

Document-oriented open source database systems
Regner, Tomáš ; Chlapek, Dušan (advisor) ; Tomášková, Barbora (referee)
One of the objectives of this bachelor thesis is to introduce readers with motives of developers for seeking alternatives to traditional relational database systems, which gradually resulted in emergence of NoSQL movement and also make them familiar with milestones and most important projects in its history. Then it introduces some basic characteristics common to NoSQL systems such as issues of scalability and distributed data processing and generally accepted categorization of NoSQL systems based on their data model. In more detail it focuses on field of document-oriented database systems, summarizes situation in this field and discusses its two currently most widely used representatives - systems MongoDB and CouchDB. It describes basic mechanisms of their operation and demonstrates meaning of their usage on examples. Then it defines evaluation criteria to compare these products and evaluate their fulfillment in currently available version of these systems.

Practical possibilities of using Apache CouchDb
Pultera, Ondřej ; Palovská, Helena (advisor) ; Strossa, Petr (referee)
This bachelor work is focused on practical possibilities of using Apache CouchDb a document oriented database system. In the first chapter I explain the basic theoretical terms and principles related to Apache CouchDb. I also briefly introduce database systems based on the relational model. The second chapter describes the architecture and properties of Apache CouchDb. In this chapter I also try to explain principles of running Apache CouchDb in a distributed system and think about need for new database systems. In the third chapter I review case studies of successful Apache CouchDb implementations. In this chapter I want to point out scenarios for which is Apache CouchDb a good candidate. In the next chapter I focus on practical usage of the system. I mention the tool for administering Apache CouchDb and describe some settings. I also show examples how to do basic operations through the HTTP interface. The examples are made with scripting languages PHP and JavaScript. This chapter introduces Apache CouchDb from the point of view of and administrator or developer. The reader of this work should understand the basic concepts of Apache CouchDb and be able to determine the usability of this system for a concrete purpose.
