The tune connections used historically to perform these operations defend birth been the postal renovation and the telephone. A relatively unfermented link is electronic info communications facilities.Your links to job connections ar limited to the mail and the telephone. Both ar slow. Both terminate with that wall of people who feed the estimator and who may make delusions. What your company needs is a better link to vocation connections and that is what electronic info supercede is all closely. To appreciate what electronic selective schooling interchange (EDI) me ans, think about all those orders, invoices, charge bills, shipment instructions, tracing requests, payment instructions, government reports, and the like that your company sends out or receives every day.Think about from each one as a bingle transaction. WHAT IS EDI? Traditionally, the off of in orderion from one company to another has been by paper documents. This is k without delayn as a paper-based organization. These documents have to be manually forwarded and droped to the destination computing device. EDI is the electronic deputize of structured business in fix upion, in standard stages, between computers, EDI eliminates the need for a paper-based system by providing an electronic link between companies. This reduces information entry tasks and improves business cycle clippings.EDI is the electronic transfer of structured business documents in an organization inbredly among groups of departments or outsidely with its suppliers, customers and subsidiaries. In EDI in doion is passed electronically from one computer to another over a state without having to be read, retyped or printed. The information transferred must have a defined structure agreed between your company, and the company or group you send and receive data from. Any company or group which uses EDI is called a TRADING match.Examples of current uses of EDI includes automatic teller machines (ATMs) in banks where EDI is used for transferring and withdrawing funds between polar bank accounts, airline reservation systems, stock win over legal proceeding and car reservation systems. USE OF EDI The data from one computer is normally not in a form suitable to be entered directly into another computer. The data may have to be lay differently before it can be entered into another computer or some items of data may not be needed at all. With EDI, all the data is converted unto an agreed standard format before it is move over the network.The computer that receives the data can then extract the information it requires. utilise EDI implies three things 1. Information is transferred electronically rather than on paper. This means that at that place is no need to enter the data manually in the destination computer. 2. Information is transferred between trading partners who have negotiated trading agreements and have formalized their data transfer system. 3. Information that is transferred complies with agreed standards for the format of the content and the transmission control mechanisms.ADVANTAGES OF EDI OVER A PAPER-BASED DOCUMENT TRANSFER SYSTEM This section highlights the advantages EDI has over a traditional paper-based document transfer system. In a Paper-based System ? A software application generates a paper document on a form. ? Copies of the document are made. Some are passed to inner(a) departments to be filled, other copies are sent to the trading partner via the postal service. ? The trading partner receives the document and retypes the informatio n on the form into their computer. This retyping often introduces errors. The trading partner generates a paper ack instantaneouslyledgement and this is sent to the originating company. The transfer of documents in a paper-based system could take a considerable length of fourth dimension. In an EDI System ? The application program generates a excite, which contains the touch on document. ? The document is converted to an agreed standard format. ? The commove cabinet containing the document is sent electronically over the network. This network links the originating company and its trading partner. ? The file containing the document arrives at the trading partner.It is translated into the correct format and transferred to the recipients application. ? A receipt is automatically generated and sent over the network t the originating company. EDI transmits documents to the trading partners application in a very short period of time and with no human intervention. HOW EDI WORKS? Rega rdless of the format chosen, companies utilize EDI communicate with their trading partners in one of two ways Either they exchange data with several(prenominal) trading partners directly or they interact with multiple companies by means of with(predicate) a central information clearing-house.In the latter(prenominal) case, all transactions are funneled through a third partys computer system, which routes them to the appropriate pass receivers computer. This enables the transmitter to communicate with an unlimited number of trading partners without worrying about proprietary systems, audit trails, variable transmission speeds, and general computer compatibility. Basically, here is how EDI works 1. Prior to any computer work, representatives of two companies interested in exchanging data electronically meet to specify the applications in the EDI standard, which they will implement. 2. distributively company adds EDI programs to its computer to translate company data in standard f ormats for transmission, and for the reverse translation on the data it receives. 3. Then, as often as operationally requires the two companies exchange data electronically in the standard formats. The data transmitted originates from records in the senders database after the sender confirms that the receiver is an authorized recipient for such data. The sender composes a transmission formatted in the EDI standards, the receiver translates the formatted message to a computer record to be processed and used privilegedly.All transmissions are checked both electronically and functionally and the protocol includes procedures for error detection and correction. INFORMATION FLOW IN EDI 1. A come with collects data for its own operational or statistical requirements. This data is edited and added to its own database. 2. Pertinent information is extracted by the company from its database, summarized if necessary, constructed into EDI transaction sets, and transmitted to the company or org anization requiring it for valid reasons. 3. The frequency for preparing this information is determined by the operational requirements of each recipient. . A communications link for transmission is established jibe to the standard communications protocol. 5. The recipient of the information receives the transmission and checks it for its physical characteristics (parity, check character, transmission mode). Retransmission is requested if an error is detected in the physical characteristics of the transmission. 6. The receiver checks the functional characteristics of the data. A message is transmitted to the original sender to acknowledge the transmission and to identify any errors detected. . The receiver processes the information received according to its own internal procedures and timing requirements. EDI COMPONENTS A typical EDI system implements a specific set of EDI by enabling the exchange of business documents. It accepts documents from business software applications, conv erts the document to a standard format and sends it to another software application or trading partner. EDI system converts generic EDI messages (in EDIFACT or any other EDI standard) format to RDBMS format and from RDBMS format to EDI format. in that respect are EDI application programs for software developers to configure EDI to work with the various user application software programs. There is normally no end-user interaction with EDIit is entirely within the background of the EDI system. RDBMS database contains the data to be translated into EDI format and where EDI data is to be converted (and written) to. EDI treats the application database genericallyit reads and writes to the tables and fields specified according to the message mapping created by the EDI Administrator during EDI message configuration.These are done by EDI Configuration programs under the purview of EDI. There are three main components in an EDI system 1. use good- Providers the means of integrating existin g or new applications into the EDI system. 2. exposition Service-Converts data from internal format standards to an extraneous format and translates data from an external format to an internal format standard. 3. Communication Service-Passes documents into a network via the agreed communication protocol.Internal format Transmission Tranmission TRADING files files files PARTNER DocumentsApplicationTranmission Communication BusinessService Service Service Application FILE TYPES EDI creates the next files as a document passes through the system ? Internal Format File (IFF) ? outer Format File (EFF) ? Transmission File Each of these files is described in the following sections.Internal Format File An internal format file (IFF) contains a single document for a single trading partner. Internal format file is principally for EDIs own use. External Format File The external format file (EFF) contains the same data as the internal format file translated into the appropriate standard docume nt format. Transmission File A transmission file contains one or more documents for the same trading partner. Documents of the same type are packaged together in functional groups. The functional groups going to one trading partner are packaged into an interchange set.An interchange set contains one or more functional groups of documents with the same sender and receiver. TRADING PARTNER A Document Type 1 1Functional groupInterchange 1 Set Document Type 2 2Functonal 2 Group TRANSMISSION FILE EDI SERVICES The three EDI services all perform different tasks. The following sections give an overview of what happens in each of three services. Application Service The Application Service provides the link between a business application and EDI. It allows you to send document to, and receive documents from, an EDI system.A set of callable routines is used to transfer documents from the business application into EDI. Documents destinations can be every intra-company or to external companies, i. e. , trading partners. The EDI Application Service holds each incoming and surmount document as a single internal format file. EDI converts the document to a standard format and sends it to the trading partner using the relevant communication protocol. A number of different standards and communication protocols are available. The following list describe what happens in the Application Service For outgoing documents The business application uses the callable routines to send a document from the business application to the Application Service. The document is now in the EDI system and is called internal format file. ? The Application Service sends the document in the internal format file to the Translation Service. For incoming documents ? The Application Service receives an internal format file from the Translation Service. ? The Application Service makes the data in the internal format file available in database so that the business application can fetch the document from EDI.A callable interface is used to do this. APPLICATION SERVICE File server Internal Formal File Callable RoutinesInternalFormat File Translation Service ? Converts outgoing documents from an internal format file to an agreed external format. ? Translates incoming documents from an external format to th EDI internal format file. The external document standards that a EDI system supports are EDIFACT, X12, TDCC, and ODETTE The following lists describe what happens in the Translation Service For outgoing documents The Translation Service receives a document in the internal format file from the Application Service. It converts the internal format file to the appropriate external standard (either EDIFACT, X12, TDCC, or ODETTE). The file is now an external format file. ? The Translation Service combines one or more external format files into a transmission file. ? The Translation Service now sends the transmission file to the Communication Service. For incoming documents ? The Translation Serv ice receives a document n the transmission file from the Communication Service. ? Separates the transmission file to produce external format files. It translates each external format file, which may be in an external standard (either EDIFACT, X12, TDCC, or ODETTE) to the internal format file. The file is now an internal format file. ? The translation Service now sends the internal format file to the Application Service. Communication Service The Communication Services sends and receives transmission files to and from the trading partners either directly or by using a third-party service called a Value Added Network (VAN). The following lists describe what happens in the Communication Service For outgoing documents The Communication Service receives a transmission file from the Translation Service. It checks the file to see which trading partner it has to be sent to. When it has identified the type of connection to be used for this trading partner t determines which gateway to use. ? The Communication Service sends the transmission file to the trading partner. For incoming documents ? The Communication Service receives a transmission file from the trading partner. The file arrives through one of the gateways that EDI supports. ? The Communication Service sends the transmission file to the Translation Service. familiar FORMAT FILE DOCUMENTS BUSINESS APPLICATIONS DOCUMENTS INTERNAL FORMAT FILEAPPLICATION SERVICETranslation Service ?

CONCLUSION By eliminating the paperbased documents the EDI was introduced. It is the new technology that overcomes the traditional paperbased documents. By using EDI we can transmit the data a t electron speed. So it is a time sparing process and also low cost as compared with telephone system. notwithstanding though there are more advantages with EDI there are some disadvantages also. To feed the data into computer, work is compulsory. By examine with computer speed human speed is a bottleneck.And also errors may occur at the time of data feeding. These errors can change the managerial decisions. Another problem if we want send more data urgently, first we feed it into computer and then send it to the destination. To feed more data requires more time. Even though the telephone cost is very high as compared to EDI process, we must use telephone installment in these cases. So in these cased we cant use EDI system. FILE SERVER CALLABLE ROUTINES MANAGEMENT port wine FILE SERVER C TFB T TFS MANAGEMENT INTERFACE
