Pervasive Systems Architecture and the Main Related Technologies

After introducing the main architectural issues concerning Pervasive Systems, this chapter deals with the essential technological aspects involved in their implementation and deployment. Being it focused on Data Management, we shall introduce the main problems and solutions related to Real-Time Data and the usage of Main-memory Database Management Systems. We will quickly review also some typical advanced data management topics that are useful prerequisites for the subsequent chapters: aspects of Big Data management, Linked Open Data, generalities of information integration including multimedia information management, issues related to the mobility of both users and information sources (e. g.: object tracking, dynamic environmental changes, etc.), the usage of social networks (Facebook, Twitter and others) as information sources and, last but not least, aspects related to the dependability of the system mainly focusing on security and privacy. The material in this chapter will be introductory and will make extensive reference to the existing literature on the different topics
