Flash Memory as Storage for Read-intensive Database full paper ieee

Using Flash Memory as Storage for Read-intensive Database Abstract—Flash memory is now widely deployed as data storage for mobile devices such as mobile phones, digital cameras and PDA’s. Since the gap of access time to main memory and disk continue growing, flash memory becomes more attractive for speeding up data analysis application as a faster non-volatile storage in laptops and personal computers. We may expect that flash memory will finally take the place of magnetic disk in the next few years. Therefore, it is possible for us to consider running a database system on the flash computing platforms. However, disk-based database technology can not be used on flash memory directly because of its different characteristics from magnetic disk. In this paper, we make an analysis of the characteristics of flash memory, and propose that a read-intensive database system should be run on the flash platform. It makes use of the characteristics of flash memory effectively to acquire more benefits by using traditional database technology on flash memory. Keywords- Read-intensive Database; Flash-Based DBMS; NAND Flash;Non-volatile storage; Write-intensive Database;

Virtual Database Technology for Distributed Database abstract ppt

Seminar Papers Presentations IEEE ppt topics abstract on Virtual Database Technology for Distributed Database (Seminar Paper Presentations)
Abstract:In this paper, our research objective is to develop a database virtualization technique so that data analysts or other users who apply data mining methods to their jobs can use all ubiquitous databases in the Internet as if they were recognized as a single database, thereby helping to reduce their workloads such as data collection from the Internet databases and data cleansing works. In this study, firstly we examine XML scheme advantages and propose a database virtualization method by which such ubiquitous databases as relational databases, object-oriented databases, and XML databases are useful, as if they all behaved as a single database. Next, we show the method of virtualization of ubiquitous databases can describe ubiquitous database schema in a unified fashion using the XML schema. Moreover, it consists of a high-level concept of distributed database management of the same type and of different types, and also of a location transparency feature. Finally, we develop a common schema generation method and propose the virtual database query language for use in a virtualized ubiquitous database use environment.

Temporal Reflective Database Access Control (TRDBAC) Paper Presentation

Seminar Papers Presentations IEEE ppt topics abstract on (TRDBAC) Temporal Reflective Database Access Control (Seminar Paper Presentations)
Abstract: Database access control policies can become extremely complicated and complex in large databases such as hospital medical systems, banks and enterprise resource planning systems of large enterprises etc. The complexity in access control policies may results in security breaches if the policies are ambiguous, not well defined and implemented incorrectly. e.g. HSBC database security breach reported in year 2006 in which an ex-employee swiped away almost 24,000 customers accounts due to incorrect access policies. The access control policies define the rights and privileges of users on database objects. In order to keep these database systems secure, the database security should provide controlled, protected access to the contents of a database as well as preserve the integrity, consistency, and overall quality of the data. In order to implement the consistent database access control policies, a number of models have been developed by the database security community such as, discretionary (DAC) and mandatory (MAC) access control models, role-based access control model (RBAC), reflective database access control (RDBAC). RDBAC is a relatively new and more expressive access control model that provides a more fine-grained level control than the previous models. Move over database privilege is expressed as a database query itself, rather than as a static privilege contained in an access control matrix.

Abstract:You hit the power button on your television and it instantly comes to life. But do the same thing with your computer and you have to wait a few minutes while it goes through its boot up sequence. Why can't we have a computer that turns on as instantly as a television or radio? IBM, in cooperation with Infineon, is promising to launch a new technology in the next few years that will eliminate the boot-up process. Magnetic random access memory (MRAM) has the potential to store more data, access that data faster and use less power than current memory technologies. The key to MRAM is that, as its name suggests, it uses magnetism rather than electrical power to store data. This is a major leap from dynamic RAM (DRAM), the most common type of memory in use today, which requires a continuous supply of electricity and is terribly inefficient. Twenty-five years ago, DRAM overtook ferrite core memory in the race to rule the PC memory market. Now it looks like ferromagnetic technology could be making a comeback, with IBM Corp. and Infineon Technologies charging a joint team of 80 engineers and scientists with the task of making magnetic RAM (MRAM) a commercial reality within four years.

Computer memory based on the protein bacterio-rhodopsin seminar topic download

Seminar Papers Pharmacy Presentations technical IEEE ppts topics abstract on Computer memory based on the protein bacterio-rhodopsin (Seminar Paper Presentations)
Abstract:Computers have gone through their own evolution in storage media. In the forties, fifties, and sixties, everyone who took a computer course used punched cards to give the computer information and store data.In 1956, researchers at IBM developed the first disk storage system. This was called RAMAC (Random Access Method of Accounting and Control).
Since the days of punch cards, computer manufacturers have strived to squeeze more data into smaller spaces. That mission has produced both competing and complementary data storage technology including electronic circuits, magnetic media like hard disks and tape, and optical media such as compact disks.

Abstract:The purpose of the paper is to examine the underlying components within distributed database architecture. Understanding the task of a distributed database management system will lead to a successful design, which will provide scalability and accessibility. When developing a distributed database system there is a need to address the importance of security issues that may arise and possibly compromise the integrity of the system. We further propose solutions for some of the security concerns that pertain to a distributed database system.

Paper presentation on Plastic memory Abstract

Seminar Paper Pharmacy Presentations technical IEEE topics Abstract papers on Plastic Memory
Abstract: A conducting plastic has been used to create a new memory technology which has the potential to store a mega bit of data in a millimeter- square device-10 times denser than current magnetic memories. This device is cheap and fast, but cannot be rewritten, so would only be suitable for permanent storage.The device sandwiches a blob of a conducting polymer called PEDOT and a silicon diode between perpendicular wires.
The key to the new technology was discovered by passing high current through PEDOT (Polyethylene dioxythiophene) which turns it into an insulator, rather like blowing a fuse .The polymer has two possible states- conductor and insulator, that form the one and zero, necessary to store digital data. However tuning the polymer into an insulator involves a permanent chemical change, meaning the memory can only be written once.
