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.

Oracle Database Management System is system software for creating and managing databases. The ODBMS provides users and programmers with a systematic way to create, retrieve, update and manage data.

Oracle RAC is a unique technology that provides high availability and scalability for all application types on Database level by creating more than one instance, distributed on more than one server connecting to one Database.

Having multiple instances access a single database prevents the server from being a single point of failure. Oracle RAC enables you to combine smaller commodity servers into a cluster to create scalable environments that support mission critical business applications. Applications that you deploy on Oracle RAC databases can operate without code changes.

Oracle Data Guard ensures high availability, data protection, and disaster recovery for enterprise data. Data Guard provides a comprehensive set of services that create, maintain, manage, and monitor one or more standby databases to enable production Oracle databases to survive disasters and data corruptions.

Single Sign-On (SSO) is a property of access control of multiple related, but dependent software systems. With this property a user logs in with a single ID and password to gain access to a connected system or systems without using different usernames or passwords, or in some configurations seamlessly sign on at each system.

Authentication is the process by which you verify that someone is who they claim to be. Usually this involves a username and a password. An unauthenticated user is one who has not yet provided credentials in the form of a username and password. Authorization is the process of determining whether the person, once identified is permitted to have access to the resource. This is usually determined by finding out if that person is part of a particular group. Oracle E-Business Suite single sign-on integrations allow for seamless authentication to multiple systems with one user id and password.

One reason to consider a single sign-on integration for your Oracle E-Business Suite environment is to provide a single login account for Oracle E-Business Suite and other applications in your environment.

Oracle Access Manager is Oracle Identity Management's solution for web access management and user identity administration. Oracle Access Manager is designed to support complex, heterogeneous enterprise environments. As a key component of Oracle Fusion Middleware, it ensures ready support for Oracle's current and future ERP, CRM and Collaboration suite applications.
Oracle Access Manager consists of the Access System, and the Identity System. The Access System secures applications by providing centralized authentication, authorization and auditing to enable single sign-on and secure access control across enterprise resources. The Identity System manages information about individuals, groups and organizations. It enables delegated administration of users, as well as self-registration interfaces with approval workflows. These systems integrate seamlessly and may be deployed together or individually.
