Abstract: The dream of computing power as readily available as the electricity in a wall socket is coming closer to reality with the arrival of grid and cloud computing. At the same time, databases grow to sizes beyond what can be efficiently managed by single server systems. There is a need for efficient distributed database management systems (DBMSs). Current distributed DBMSs are not built to scale to more than tens or hundreds of sites (i.e., nodes or computers). Users of grid and cloud computing expect not only almost infinite scalability, i.e., at least to thousands of sites, but also that the scale is adapted automatically to meet the demand, whether it increases or decreases. This is a challenge to current distributed DBMSs. The purpose of this paper is to present an introduction to Distributed Databases which are becoming very popular now a days. Today’s business environment has an increasing need for distributed database and Client/server applications as the desire for reliable, scalable and accessible information is Steadily rising. Distributed database systems provide an improvement on communication and data processing due to its data distribution throughout different network sites.

Keywords: Distributed databases fundamentals, current research: query optimization, distribution optimization, fragmentation optimization.

This definition is better than the "shared data" definition because it helps eliminate multiuser databases from the groupware category. Yet electronic mail fits this definition, as well as some other software sharing tools that experts are still debating.…

    252 Management Information Systems REAL WORLD ~ CASE Amazon, eBay, and Google: Unlocking and Sharing Business Databases The meeting had dragged on for more than an hour that rainy day in Seattle, and Jeff Bezos had heard enough. The CEO had rounded up 15 or so senior engineers and managers in one of Amazon's offices to tackle a question buzzing inside the company: Should Amazon bust open the doors of its most prized data warehouse, containing its myriad databases, and let an eager world of entrepreneurs scavenge through its data jewels? For several years, scores of outsiders had been knocking on Amazon's door to gain access to the underlying data that power the $7 billion retailer: product descriptions, prices, sales rankings, customer reviews, inventory figures, and countless other layers of content. In all, it was a data vault that Amazon had spent more than 10 years and a billion dollars to build, organize, and safeguard.…

    The amount of deployed instances of Microsoft SQL Server in the enterprise is on the rise as a database management system. Microsoft set out to provide an effective database management system that meets multiple goals for information technology organizations. SQL Server, a Microsoft product, is designed to deliver scalable solutions while offering ease of use and deployment, self maintenance and tuning, low resource overhead, and low administrator skill set requirements. The seeming rise in popularity of SQL Server has resulted in an upsurge of installations in the corporate environment. This trend is frequently described as server sprawl. In some instances, this has led to uncoordinated installations, wasted hardware and licenses, lack of standards in an enterprise, and security holes. These problems can be mitigated by server consolidation. Consolidation is the combination of SQL Server databases running on different systems that are usually geographically dispersed, onto a smaller number of more powerful systems in a central location. The result is greater performance and reliability as well as an easing of administration duties.…

    Distributed Database

    A distributed Database Management System (DDBMS) is a database in which storage devices are not all attached to a common processing unit such as the CPU. It may be stored in multiple computers, located in the same physical location; or may be dispersed over a network of interconnected computers. Unlike parallel systems, in which the processors are tightly coupled and constitute a single database system, a distributed database system consists of loosely coupled sites that share no physical components. Collections of data (e.g. in a database) can be distributed across multiple physical locations. A distributed database can reside on network servers on the Internet, on corporate intranets or extranets, or on other company networks. The replication and distribution of databases improves database performance at end-user worksites.…
