Data virtualization is an approach to data management that allows an application to retrieve and manipulate data without requiring technical details about the data, such as how it is formatted at source, or where it is physically located, [1] and can provide a single customer view (or single view of any other entity) of the overall data.
There is no actual data integration in the constituent disparate databases as a result of data federation. Through data abstraction, federated database systems can provide a uniform user interface, enabling users and clients to store and retrieve data from multiple noncontiguous databases with a single query—even if the constituent databases ...
Federated architecture (FA) is a pattern in enterprise architecture that allows interoperability and information sharing between semi-autonomous de-centrally organized lines of business (LOBs), information technology systems and applications. Architecture areas of concern. Organisational architecture; Business architecture; Process architecture
A federation is a group of computing or network providers agreeing upon standards of operation in a collective fashion.. The most widely known example is the Internet, which is Federated around the Internet Protocol (IP) stack of protocols.
Federation Execution: A session, where a set of federates execute together in a federation with a specific objective, using the same RTI and FOM. Federation Object Model (FOM): A document that specifies object classes, interaction classes, data types and additional data that is used for the information exchange in a federation. A FOM is an XML ...
Database virtualization is the decoupling of the database layer, which lies between the storage and application layers within the application stack. Virtualization of the database layer enables a shift away from the physical, toward the logical or virtual. Virtualization enables compute and storage resources to be pooled and allocated on demand.
Enterprise information integration (EII) is the ability to support a unified view of data and information for an entire organization.In a data virtualization application of EII, a process of information integration, using data abstraction to provide a unified interface (known as uniform data access) for viewing all the data within an organization, and a single set of structures and naming ...
[6] [7] All physical data-center resources reside on a single administrative platform for both hardware and software layers. [8] Consolidation of all functional elements at the hypervisor level, together with federated identity management , was promoted to improve data-center inefficiencies and reduce the total cost of ownership (TCO) for data ...
