Oracle one on one training course (Part - 1)

An Oracle database is a collection of data treated as a unit. The purpose of a database is to store and retrieve related information. A database server is the key to solving the problems of information management. In general, a server reliably manages a large amount of data in a multiuser environment so that many users can concurrently access the same data. All this is accomplished while delivering high performance. A database server also prevents unauthorized access and provides efficient solutions for failure recovery.

 
Oracle Database is the first database designed for enterprise grid computing, the most flexible and cost effective way to manage information and applications. Enterprise grid computing creates large pools of industry-standard, modular storage and servers. With this architecture, each new system can be rapidly provisioned from the pool of components. There is no need for peak workloads, because capacity can be easily added or reallocated from the resource pools as needed.

The database has logical structures and physical structures. Because the physical and logical structures are separate, the physical storage of data can be managed without affecting the access to logical storage structures.

Cloud computing

  Cloud computing is a technology model that enables access to a shared pool of computing resources and services over the Internet. Instead of owning and maintaining physical servers and data centers, organizations can use cloud computing services provided by cloud service providers. These services include computing power, storage, databases, networking, software, and more. Cloud computing services can be categorized into several main models: Infrastructure as a Service (IaaS): IaaS provides virtualized computing resources over the Internet. Users can rent virtual machines, storage, and networking components, allowing them to run and manage their operating systems and applications. Platform as a Service (PaaS): PaaS offers a platform that includes the underlying infrastructure, development tools, and services to build, deploy, and manage applications. Users focus on coding and application development while the platform handles the underlying infrastructure. Software as a Service ...
