The ever increasing demand for more storage capacity in an ever shrinking form factor as well as the pressure to decrease the price per storage unit in $/Gbyte have been a major driving force for substantial world-wide research and development activities to increase storage densities by various means. For many decades, silicon-based semiconductor memory chips and magnetic hard drives (HDD) have been dominating the data-storage market. So far, both technologies have improved their storage densities by about 100% per year, while reducing the cost per gigabyte. However, the areal densities that today's magnetic recording technologies can achieve will eventually reach a limit imposed by the well-known superparamagnetic effect, which today is conjectured to be on the order of 250 Gbit/square inch for longitudinal recording. Several proposals have been formulated to overcome this limit, for example, the adoption of patterned magnetic media,<br> where the biggest challenge remains the patterning of the magnetic disk in a cost-effective manner. In the case of semiconductor memories, such as DRAM, SRAM, Flash etc., the challenges are predominately in lithography to define and fabricate sub-100-nm FET gates as well as very thin gate-oxide materials.</font></p> <p><font face="Arial, Helvetica, sans-serif" size="2" color="#000066"><br> Today ultrahigh storage densities of up to 1 Tb/in. or more can be achieved by using local-probe techniques to write, read back, and erase data in very thin polymer films. The thermomechanical scanning-probe-based data-storage concept, internally dubbed "millipede", combines ultrahigh density, small form factor, and high data rates. High data rates are achieved by parallel operation of large 2D arrays with thousands micro/nanomechanical cantilevers/tips that can be batch-fabricated by silicon surface-micromachining techniques. The inherent parallelism, the ultrahigh areal densities and the small form factor may open up new<br> perspectives and opportunities for application in areas beyond those envisaged today.</font></p> </td> </tr> <tr> <td colspan="2"> <hr> </td> </tr> <tr> <td colspan="2"> <p><b><font size="3" face="Arial, Helvetica, sans-serif">About the speake<font color="#000066">r </font></font></b></p> <p><font face="Arial, Helvetica, sans-serif" size="2" color="#000066">Evangelos Eleftheriou received a B.S degree in Electrical Engineering from the University of Patras, Greece, in 1979, and M.Eng. and Ph.D. degrees in Electrical Engineering from Carleton University, Ottawa, Canada, in 1981 and 1985, respectively.

It is a strategic area of investment by software companies today whose goal is to provide a unified view of the data regardless of differences in data format, data location and access interfaces, dynamically manage data placement to match availability, currency and performance requirements, and provide autonomic features that reduce the burden on IT staffs for managing complex data architectures. This paper describes the motivation for integrating information for on demand computing, explains its requirements, and illustrates its value through usage scenarios. As shown in the paper, there is still tremendous amount of research, engineering, and development work needed to make the information integration vision a reality and it is expected that software companies will continue to heavily invest in aggressively pursing the information integration vision. </font></p> </td> </tr> <tr> <td colspan="2"> <hr> </td> </tr> <tr> <td colspan="2"> <p><b><font size="3" face="Arial, Helvetica, sans-serif">About the speake<font color="#000066">r </font></font></b></p> <p><font face="Arial, Helvetica, sans-serif" size="2" color="#000066">Nelson Mattos, Ph.

While this strict separation of concerns has lasted for many years, in this talk I will argue that the gap has recently narrowed to the point where the two fields now have much to say to each other.</font></p> <p><font face="Arial, Helvetica, sans-serif" size="2" color="#000066">Networking research has traditionally focused on enabling communication between network hosts. This research program has produced a myriad of specific algorithms and protocols to solve such problems as error recovery, congestion control, routing, multicast and quality-of-service. It has also led to a set of general architectural principles, such as fate sharing and the end-to-end principle, that provide widely applicable guidelines for allocating functionality among network entities. </font></p> <p><font face="Arial, Helvetica, sans-serif" size="2" color="#000066">This research and design paradigm has been exclusively host-centric; hosts are assumed to know which other hosts (or multicast groups) to contact, and the research focuses on making the resulting host-host communication robust and efficient. However, an increasing number of applications involve accessing particular data objects whose location can't easily be determined within the current Internet architecture. Networking researchers have consequently begun looking at a variety of approaches that are more data-centric than host-centric, in that the basic abstractions refer to the name of the data rather than its location. </font></p> <p><font face="Arial, Helvetica, sans-serif" size="2" color="#000066">This data-centric trend is most visible in two areas of networking research: sensornets and distributed hash tables. Data-centrism is natural for sensornets because the identity of individual nodes is far less important than the data they collect. Traditional networking has toyed with data-centrism in various limited forms (e.g., web redirection, intentional naming), but the recent advent of distributed hash tables has led to a much broader and more explicit engagement with the data-centric paradigm. In both the sensornet and traditional Internet cases, data-centric research initially focused on how to efficiently access data based on logical names. More recent research has used distributed data structures to support more general queries. </font></p> <p><font face="Arial, Helvetica, sans-serif" size="2" color="#000066">Networking researchers have thus unwittingly wandered into the Coddian world of physical data independence, a territory far more familiar to database researchers.
