Abstract
Ensuring the correctness of multi-threaded programs is difficult, due to the potential for unexpected and nondeterministic interactions between threads. In the past, researchers have addressed this problem by devising tools for detecting race conditions, a situation where two threads simultaneously access the same data variable, and at least one of the accesses is a write. However, verifying the absence of such simultaneous-access race conditions is neither necessary nor sufficient to ensure the absence of errors due to unexpected th ....etc

The profound improvements in computer architectures over the last decade gave rise to In-Memory Database technology. CPU performance (as measured by circuit density) has been doubling, on average, every year and a half Memory chips have doubled in capacity at half the cost in the same intervals. Today, a gigabyte of physical memory for a server costs around $100. Once prohibitive, the cost of RAM is no longer a factor in the consideration of production-scale In-Memory Databases for front-office applications. Back-office systems and data warehou ....etc

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
u ....etc

Atomicity is a highly desirable property for achieving application consistency in service compositions. To achieve atomicity, a service composition should satisfy the atomicity sphere, a structural criterion for the backend processes of involved services. Existing analysis techniques for the atomicity sphere generally assume complete knowledge of all involved backend processes. Such an assumption is invalid when some service providers do not release all details of their backend processes to service consumers outside the organizations. To addres ....etc

Virtual Database Technology for Distributed Database



introductionn

In a large modern enterprise, it is almost inevitable that different portions of the organization will use different database management systems to store and search their critical data. Competition, evolving technology, mergers, acquisitions, geographic distribution, and the inevitable decentralization of growth all contribute to this diversity. Yet it is only by combining the information from these system ....etc

Web database publishing is a new way to publish information electronically. A typical Web database publishing system has a Web browser as its user interface, a database server as its information store, and a Web server connecting the two. The basic idea of this project is to use JDBC to search databases directly from an Internet Web browser. The database is kept on an NT server. JDBC is used to interact with Web pages. This project uses a simple interface to help the administrator update the database on the Web server. Some security issues are ....etc

VIRTUAL DATABASE TECHNOLOGY FOR DISTRIBUTED DATABASE (DATAMINING)


ABSTRACT:
The main aim of this project is to take the results of different database and to store it in a single database so that there will be no need for the user to search for the specific item on different databases. In this application mainly what we are doing is collecting the data from different search engines while searching by the different user saving in one database so whenever user is sea ....etc

Cell Centered Database

Abstract :

The Cell Centered Database (CCDB), launched in 2002 as one of the first Internet databases for cellular imaging data, makes 3D microscopic imaging data available to the structural biology and neuroscience communities. This database houses structural and protein distribution information derived from confocal, multiphoton, and electron microscopy, including correlated microscopy. Through this publicly accessible resource based at the University of California, San Diego (UCSD), researchers can query the ri ....etc
