Data feed
Encyclopedia
Data feed is a mechanism for users to receive updated data from data sources. It is commonly used by real-time
applications in point-to-point settings as well as on the world-wide web. The latter is also called Web feed

. Data feeds usually requires structured data. At the present time unstructured data, e.g. HTML pages, dominate the Web. As a result, data feeds have the potential to make a bigger impact on the Web in the future.
. Data will be encoded by Semantic Web languages like RDF
or OWL
according to many experts' visions. So, it is not difficult to envision data feeds will be also in the form of RDF or OWL. A big advantage of providing semantic data feeds, i.e. feeding data in Semantic Web standards, is that the data can then be readily consumed and reused by other computers. Examples of semantic data feed are available on the Ufeed online service. Ufeed allows users to create feeds in RDF format for various types of data, which include product information, news, events, job openings and studies.
Real-time computing
In computer science, real-time computing , or reactive computing, is the study of hardware and software systems that are subject to a "real-time constraint"— e.g. operational deadlines from event to system response. Real-time programs must guarantee response within strict time constraints...
