2、l Science and Innovation Campus, Chilton, Didcot, Oxfordshire OX11 0QX UKAbstractTraditional database research has developed technology to ensure that the database even when distributed represents the world of interest with integrity and a consistent state. Important concepts have been developed and

3、 proven. However, the internet of things challenges all this. Very large numbers of nodes handle volumes that are vast, the speed is fast and the data/information space is global indeed with space data universal. This poses challenges. What does the concept of a state mean when the information map o

4、f the real world of interest is represented across millions of nodes, many of which are updating in real-time? What does a transaction look like when the data being updated is spread across hundreds or thousands of nodes with differing update policies? Worse, how does one roll back or compensate a t

5、ransaction? We have already seen database research applied to semi-structured data, to streamed data, and real-time applications. Is it possible for these techniques to be applied to the internet of things? The internet of things opens up more opportunities for security compromises. How do we develo

6、p trust band security techniques across multiple policies? How do we prevent the unauthorized use of private information yet permit authorized use? We need dynamic trust, security, and privacy management. Do we need a new theoretical framework?KeywordsDatabase, Future internet, Integrity, Process, S

7、tate, Transaction, Workflow. 1. IntroductionThere is much activity in Europe and the world on predicting the future of information and communication technology (ICT). There are roadmapping exercises for R and D in various domains to meet that predicted future. The EC has set up expert groups and/or

8、Projects covering GRIDs, CLOUDs, Service-Oriented Architectures, quantum and bio-computing, new materials, humancomputer interaction, and cognitive technology among others. There is much discussion of Web2.0 and beyond. The Internet of Things (http:/ en.wikipedia.org/wiki/Internet_of_Things) is a st

9、rong theme with a recent EC (European Commission) conference (May 2009) dedicated to it. The formation of the FIA (Future Internet Assembly) underpins the groundswell of enthusiasm for this idea, and Issue 77 of ERCIM News 1 has Future Internet Technology as the special theme, with a foreword by Viv

10、iane Reding, EC Commissioner for Information Society and Media, emphasizing the importance. Europe is establishing an e-Infrastructure and the US is establishing its Cyberinfrastructure.Database researchers (with a few notable exceptions) have not been very prominent in these discussions. This is su

11、rprising, as the movement toward takeup of these new technologies by the business world pioneered in the research field will require, at the least, interoperation with the existing database technology, and most likely a further wholesale evolutionary or revolutionary developmentof the database techn

12、ology, to adapt to the new environment. Database research has moved to include semi-structured data and its processing and managing of data streams. There is work on schema matching and mapping for interoperation (sometimes in the context of Dataspaces), and on domain ontologies. There is still ongo

Work on performance or query optimization with new algorithms continues, as does optimized storage architecture including P2P (Peer to Peer).Where are the advances in database research matching and/or contributing to the huge ad

It is based on the architecture proposed for the UK e-Science program 2 and is represented in Figure 1.Let us imagine a possible state in 20 years time. The problems facing Europe and the world

Persons are connected to the e-infrastructure via personal computer devices that are continuously online. Th
