Digital Image Data Management / 23 G eeral D iagostic R adlogy The American College of Radiology, with more than 30,000 members, is the principal organization of radiologists, radiation oncologists, and clinical medical physicists in the United States. The College is a nonprofit professional society whose primary purposes are to advance the science of radiology, improve radiologic services to t...

The increasing availability of cheap, small, low-power sensor hardware and the ubiquity of wired and wireless networks has led to the prediction that ‘smart evironments’ will emerge in the near future. The sensors in these environments collect detailed information about the situation people are in, which is used to enhance information-processing applications that are present on their mobile and...

Introduction In major corporations the winds of globalisation and the efforts to seek further process efficiencies are accompanied by the frequent and massive deployment of large ICT platforms and business redesigns. ERP packages are one example of this drive to wire into software and hardware new routines, processes and practices in ways that are aligned with the prevailing globalisation and r...

Big data management is a reality for an increasing number of organizations in many areas and represents a set of challenges involving big data modeling, storage and retrieval, analysis and visualization. However, technological resources, people and processes are crucial to facilitate the management of big data in any kind of organization, allowing information and knowledge from a large volume o...

Building on achievements and experience gained through the EU project DAMOCLES and international data management during the International Polar Year, ACCESS, data management was implemented using the same platform as used for DAMOCLES. A metadata-driven approach through which all datasets are properly described with discovery and use metadata was chosen in order to simplify data management and ...

In this paper we develop a framework for the support of temporal data. The concept of a time sequence is introduced, and shown to be an important fundamental concept for representing the semantics of temporal data and for efficient physical organization. We discuss properties of time sequences that allow the treatment of such sequences in a uniform fashion. These properties are exploited in ord...

Data centers form the underpinnings of the global technology revolution that is cloud computing. There is enormous pressure for data center growth and expansion, to meet the computational demands of an increasingly digital world. With energy costs overtaking server costs in data centers, energy is fast becoming a significant bottleneck to data center scale-out. Further, the global data center e...

In this chapter we illustrate fundamental notions of Data Management. We start from the basic concepts of database schema and instance, illustrating how they are handled within dictionaries in relational databases. We then address, from a general point of view, the notion of data model as a means for the representation of information at different levels of details, and show how dictionaries can...

We describe the power and potential of data journalism, where news stories are reported and published with data and dynamic visualizations. We discuss the challenges facing data journalism today and how recent data management tools such as Google Fusion Tables have helped in the newsroom. We then describe some of the challenges that need to be addressed in order for data journalism to reach its...

Decentralized data management has been addressed during the years by means of several technical solutions, ranging from distributed DBMSs, to mediatorbased data integration systems. Recently, such an issue has been investigated in the context of Peer-to-Peer (P2P) architectures. In this chapter we focus on P2P data integration systems, which are characterized by various autonomous peers, each p...
