The results of the work are the requirements analysis, the system design considering the user options and needs and the description of the system implementation process with reference to used technology. In addition, the work includes a description and comparison of four commercial products from the user point of view, which became an initial point for requirements determination.

Submitted work describes IMS (IP Multimedia Subsystem) and focuses on services offered by this technology. In the theoretical part of the thesis is a detailed description of the IMS architecture, in the terms of its components and interfaces. Also a SIP protocol is described as the main signalling protocol, which represents the basis of the IMS architecture and RTP protocol that allows the transmission of multimedia data in real-time. Further, there are provided services that the IMS system brings. The practical part of the work describes the design and implementation of services within the IMS. It is a client-server service. Server part of the system is implemented as a SIP Servlet application. It has access to the MySQL database, which stores records of multimedia files. Client registered in the IMS network can communicate with the SIP servlet sending a request for information on such files. Following this communication, the client can play the file in his online ICP application, or download it into his PC and then play. To play and view multimedia fines is used JMF. The service is implemented in a development environment SDS Ericsson 4.1, which allows simulation of the IMS network.

This master’s thesis is focused on the network architecture of IMS (Internet Protocol Multimedia Subsystem) and development an application for IMS. IMS architecture is the convergence of fixed and mobile networks. IMS enables rapid deployment of new multimedia services. In the first chapter is showed and described architecture IMS in four layers and block model of architecture IMS. Next chapter is focused to protocols, which are used in IMS. One of the most important protocols in network IMS is SIP. This protocol is analyzed in details. For development IMS platform application was used Ericsson SDS (Service Development Studio) in version 4.1. In SDS were created applications type of client and servlet. In this master’s thesis is also used development environment NetBeans. In NetBeans was created application for management of captured images. In the same development environment was developed application that shows the contents of a database. Last chapter is devoted to analyze individual parts of communication between client and servlet, and when client uses http to download image file.

This master’s thesis deals description of the IMS (Internet Protocol Multimedia Subsystem) and shows the possibility for design applications that using services this system. The theoretical part of the thesis is focused on a detailed description of the IMS architecture, its key components and the SIP protocol that is main signaling protocol in the IMS. The practical part of the work describes the design, implementation and test of the system for reservation of tickets to cinema in the IMS. The project was created as client-server application in the development studio SDS Ericsson 4.1 FD1 with built-in IMS simulator. The client application is designed for mobile devices with support of the J2ME platform. The server part of the system is realized as SIP Servlet with access to the MySQL database. In the database are saves records about registered users, offered tickets and successful reservation. For easy work over MySQL database of the system for reservation of tickets was created the application for its administration in the Java programming language (Java SE 6). With the assistance of this application, the operators of system can add and erase the records about films, time projection and disburse tickets on the basis of knowledge of reservation ID. In the end of the work is realized SIP signaling analysis of the client registration to IMS and communication between the client application and the SIP Servlet.

In recent years, there has been tremendous growth in both the volumes of data that is produced, stored, and queried by organizations. Organizations spend more money to investigate and obtain useful information or knowledge against terabytes and even petabytes of data. Large-scale data analysis is the key functionality provided by Big Data platforms. Previously, data platforms would get the information from unstructured data in the form of files, text, and videos. In recent times, the Hadoop stack has played a vital role in Big Data, becoming the defector open source software used to process and analyze Big Data. Hops is a Hadoop distribution developed by KTH and RISE SICS. Hops modifies the Hadoop stack by moving the meta-data for YARN and HDFS to NDB, an open-source in-memory distributed database. HopsWorks is the User Interface for Hops and provides support for multi-tenant users, as well as self-service, graphical access to frameworks such as Hadoop, Flink, Spark, Kafka, and Kibana. HopsWorks currently does not provide a SQL-on-Hadoop service, although work is ongoing for supporting Hive. Presto is one of the main SQL-on-Hadoop platform, but, currently, Presto does not provide multi-tenancy support for users. This thesis investigates providing multitenancy support to Presto with the help of HopsWorks, including both the security problem and the self-service UI requirements of HopsWorks. Presto is a distributed SQL query Engine which can run SQL queries against up to petabytes of data. As HopsWorks provides UI access to services, we decided to build our UI for Presto on an existing open-source UI for Presto, called Airpal, developed by Airbnb. This provided solution of the thesis divided into two functionalities. First one, maintain two separate Applications (HopsWorks and Airpal Applications) run by the help of two JVMs and maintain ProxyServlet to control traffic between them. Second one HopsWorks-Presto-service leverages HopsWorks access-control (Data owner and Data-scientist) and self-service security model. The evaluation of the thesis used qualitative approach by comparing HopsWorks-PrestoService with standalone PrestoDB and comparing HopsWorks-PrestoService with HopsWorks without Presto-Service. / De senaste åren, har det varit en avsevärd ökning vad gäller mängden av data som produceras, lagras och som används för analys av olika organisationer. Organisationer spenderar mer pengar för att undersöka och extrahera information och insikter i enorma datavolymer på flera terabyte eller petabyte. Storskalig dataanalys är en central funktionalitet som tillhandahålls av Big Data plattformar. I tidigare tillvägagångssätt hämtade data plattformaro-strukturerade data i form av filer, texter och videoklipp. I nutid, så har Hadoop-stacken spelat en kärnroll i Big Data, och blivit en viktig öppen källkod mjukvara som används för att processera och analysera Big Data. Hops är en Hadoop distribution som har utvecklats av KTH och RISE SICS. Hops tillför ändringar till Hadoop stacken genom att migrera metadata för YARN och HDFS till NDB, en öppen källkod i-minnet distribuerad databas. HopsWorks är ett användargränssnitt för Hops och tillför stöd för flera användare, med tillgång till självservice och tjänster såsom Hadoop, Flink, Spark, Kafka och Kibana. HopsWorks stödjer i nuläget inte någon SQL på Hadoop tjänst, även om arbete utförs i nuläget för att integrera Hive. Presto är en av de mest populära SQL på Hadoop plattformarna, men i nuläget så stödjer inte Presto flera användare. Den här uppsatsen utreder stöd för flera användare i Presto med hjälp av HopsWorks, både vad gäller säkerhetsproblem och självservice i HopsWorks. Presto är en distribuerad SQL frågespråk motor som kan ställa frågor mot upp till petabyte med data. Eftersom HopsWorks tillhandahåller ett gränssnitt för att interagera med tjänster, beslutade vi oss att bygga ett gränssnitt för Presto på det existerande öppen källkod gränssnittet för Presto, vid namn AirPal, utvecklat av Airbnb. Den utvecklade lösningen för uppsatsen kan delas in i två delar. Den första delen, att hantera två separata applikationer (HopsWorks och AirPal) som kör med hjälp av två Java virtuella maskiner och använder en ProxyServlet för att kontrollera trafik mellan dom. Den andra, HopsWorks-Presto-service som tillhandahåller HopsWorks åtkomstkontroll (Dataägare och Dataforskare) och en självservice säkerhetsmodell. Utvärderingen i uppsatsen är att genom ett kvalitativt tillvägagångssätt jämföra HopsWorks-Presto-service med en fristående PrestoDB och jämföra HopsWorks-Presto-service med HopsWorks utan Presto-service.

With the rapidly development of electronic commerce, the competitions between enterprises have been getting more and more turbulent. In order to win business in such a highly competitive environment, it has to not only implement customized marketing strategy but also have a timely response whenever there is any change in the business environment. Currently, in most companies, whenever the marketing people wants to implement a new sales promotion program, he has to communicate it with the MIS department and ask it to rewrite the Web system and pages. It is quite often a very time-consuming as well as strenuous process. In this research, we have explored all popular and important sales promotion models. Based on these models, an object-oriented Web system has been designed and developed. There is an interface by which the marketing people can set the new sales promotion program and then, the Web system can execute it immediately afterwards. The interface, allows the marketing people easily to select target customers, conditions for getting bonus and contents of bonus to set a new sales promotion program. That is, the marketing people can let the Web system execute a new sales promotion program whenever he wants without the help of system programmers. In addition, the whole design is object-oriented. It lets the system have very high portability.
