A federated database system consists of component DBS that are autonomous yet participate in a federation to allow partial and controlled sharing of their data. Federated architectures differ based on levels of integration with the component database systems and the extent of services offered by the federation.
Federated architecture as database architecture was first introduced by Denis Heimbigner 1982 [3] and 1985 with the title: A Federated Architecture for Information Management: [4] "This federated database architecture allows a collection of database systems (components) to unite into a loosely coupled federation in order to share and exchange ...
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.
As such, it is an information aggregation or integration approach - it provides single point access to many information resources, and typically returns the data in a standard or partially homogenized form. Other approaches include constructing an Enterprise data warehouse, Data lake, or Data hub. Federated Search queries many times in many ...
The term may also be used when groups attempt to delegate collective authority of development to prevent fragmentation. In a telecommunication interconnection, the internal modi operandi of the different systems are irrelevant to the existence of a federation. Joining two distinct networks: Yahoo! and Microsoft announced that Yahoo!
Data consolidation – The process of capturing master data from multiple sources and integrating it into a single hub (operational data store) for replication to other destination systems. Data federation – The process of providing a single virtual view of master data from one or more sources to one or more destination systems.
Trino is an open-source distributed SQL query engine designed to query large data sets distributed over one or more heterogeneous data sources. [1] Trino can query data lakes that contain a variety of file formats such as simple row-oriented CSV and JSON data files to more performant open column-oriented data file formats like ORC or Parquet [2] [3] residing on different storage systems like ...
An Executable Architecture (EA), in general, is the description of a system architecture (including software and/or otherwise) in a formal notation together with the tools (e.g. compilers/translators) that allow the automatic or semi-automatic generation of artifacts (e.g. capability gap analysis (CGA), models, software stubs, Military Scenario Definition Language (MSDL)) from that notation ...
