(pronounced as separate letters) Short for event-driven architecture, an enterprise software infrastructure model in which events trigger the real-time exchange of messages between independent software applications. EDA relies on an event-processing agent that detects events across an enterprise and, using a push approach, notifies all of the other software applications that need to be notified of the change in data, all at the same time. For example: the e-commerce Web site of an enterprise receives an order for a product, completing a business event. An event agent detects this transaction and simultaneously notifies all other applications in the enterprise that need to know about the order, which can include such aspects as an inventory database, accounts receivable software, customer service applications, marketing and advertising monitors, and shipping software.
This method is different than more traditional methods of enterprise communication in which events are compiled in batches and then communicated across the enterprise at periodic intervals.
Short for electronic dispersion compensation, EDC technology is supported by the Optical Internetworking Forum (OIF) – a group currently defining a 10 Gbps interoperability specification targeting optical links. The transmission distance of this specification supports up to 120 km (2400 ps/nm), however, the maximum distance currently supported is specified at up to 80 km. To […]
Short for erbium-doped fiber amplifier. EDFA is an optical repeater device that is used to boost the intensity of optical signals being carried through a fiber optic communications system. An optical fiber is doped with the rare earth element erbium so that the glass fiber can absorb light at one frequency and emit light at […]
Electronic Data Gathering, Analysis, and Retrieval system was implemented by the Securities and Exchange Commission (SEC) to do two things: 1) quickly process time-sensitive information of publicly-held companies and 2) provide investors with easier access to company information. EDGAR became available to filers on July 15, 1992, and as of May 6, 1996, all domestic […]
Acronym for Enhanced Data GSM Environment. EDGE is a faster version of GSM wireless service. EDGE enables data to be delivered at rates up to 384 Kbps on a broadband. The standard is based on the GSM standard and uses TDMA multiplexing technology.
Short for Electronic Data Interchange, the transfer of data between different companies using networks, such as VANs or the Internet. As more and more companies get connected to the Internet, EDI is becoming increasingly important as an easy mechanism for companies to buy, sell, and trade information. ANSI has approved a set of EDI standards […]
