Grid Computing/Database Technology
'Grid computing isn't a product which replaces or supercedes others, but that it is simply a concept which, to make a reality, requires the use of a lot of existing and new technologies in combination." (What is the grid?). For example, in Oracle's new grid database named 10g there isn't an option which you can license called a grid. Instead, grid computing in databases as explained below is an idea of how storage and processing power should appear to users. Essentially, grid computing coordinates the use of clusters of machines to create a single logical entity. Work can then be distributed across many servers to derive benefits such as availability, scalability, and performance using low-cost components (Oracle 10g: Infrastructure for grid computing,2003).
The most important attribute of a grid database is virtualization. Virtualization is the abstraction into a service of every physical and logical entity in a grid. A database that is a part of the grid must make the physical storage of data files, the physical location of rows in a table, and the CPU power and memory allocations that are needed to access those rows, transparent to the user (What is the grid?). Provisioning, resource pooling, self-adaptive software and unified management are also key attributes of grid databases (Oracle 10g: Infrastructure for grid computing, 2003). Provisioning of things such as server requests, data, and computations requires a grid service broker than understands resource requirements and resource availability across the grid. Resource pooling is also required to achieve better resource sharing. The pooling of individual disks into storage arrays and individual servers into blade farms gives the grid runtime processes the ability to optimize the associations between service consumers and service providers. A critical grid infrastructure requirement is self-adaptive software that automates maintenance and tuning tasks traditionally performed by IT. Further, IT professionals need unified management so that they can treat groups of systems as a single logical entity so that tasks can be performed once and executed on multiple machines.

Oracle supports stored programs such as stored procedures and packages. This enables the developers to centralize application logic in the database. Oracle provides powerful functions and sub-queries in its SQL statements. Developers can distribute systems by database links, materialized views and distributed queries. This feature saves much cost for developing distributed systems and applications. And there's a lot of features integrated with Oracle, compare to other database it is
This research proposal looks to determine how the selection of a given cloud platform impacts user intention, satisfaction and long-term adoption. In order to evaluate the contributions of each of these platforms, each is briefly reviewed within the context of this literature review. First, the most commonly used one in start-up cloud database service providers, Amazon Web Services (AWS), is analyzed. AWS is comprised of the following components: Amazon DynamoDB
organizations can do to protect client data comprehensively and how they do this. It will also examine the most common forms of data customers generate, and take a look at some of the contemporary hardware and software that organizations protecting and handling data in the cloud use presently. Common Types of Customer Data Data Identity: The individual is at the core of any database, so gaining an insight into how a person
Cloud Computing Many businesses are experimenting and slowly embracing the concept of cloud computing and Web2.0 .organizations choosing projects which can reap full benefits from cloud computing and Web2.0.this evolution has began as organizations are now taking a crawl, walk run approach which is building towards an eventual implementation of cloud and Web2.0 implementation. Organizations are now following the pragmatic path towards cloud computing and Web2.0 through the adoption of new
It's a tidal wave that's going to engulf us all within the next five years. Cloud services will be a $160 billion industry by the end of 2011" (Ginovsky 2011, 21). Although the decision to transition from a traditional approach to cloud computing will depend on each organization's unique circumstances, a number of general benefits have been cited for those companies that have made the partial or complete transition to
The user, of course, sees a virtual service (appearing like the data is stored in certain icon), the actual storage could be anywhere, and could vary from day-to-day. This is an advantage to the overall efficiency of the system because storage resources can then be allocated rather than static (Smith, Computing Beyond the Firewall, 2010). Cloud services are any web-based application -- from calendars and contact applications to word processing,
