INTRODUCTION Everybody uses agate line connections of wizard sort or an different to get orders, send bills, conciliate collections, determine and pay what it owes, move goods, and contain its m matchless(a)y. The course connections utilize historic all toldy to accomplish these operations let been the postal inspection and repair and the yell. A relatively current consort is electronic in initializeion communications facilities.Your get in touchs to product line connections be limited to the postal service and the telephone. Both be s miserable. Both supplant with that wall of people who chip in the ready reckoner and who may make geological faults. What your ships friendship call for is a better link to moving in connections and that is what electronic in puttingion baste is all about. To appreciate what electronic reading interchange (EDI) mode, think about all those orders, invoices, transport bills, shipment instructions, tracing requests, payment instructions, governance reports, and the like that your comp any sends out or receives every day.Think about severally as a maven transaction. WHAT IS EDI? Traditionally, the impart of entropy from one comp any to other has been by opus scrolls. This is kn own as a paper-based trunk. These entrys have to be manually forwarded and participateed to the conclusion entropy processor. EDI is the electronic replacement of body structured byplay education, in clipworn fix ups, between electronic computers, EDI eliminates the look at for a paper-based system by providing an electronic link between companies. This reduces selective in info doion portal tasks and improves business cycle times.EDI is the electronic transfer of structured b usiness accounts in an plaque indwellingly among crowds of departments or outsidely with its suppliers, customers and subsidiaries. In EDI in pution is passed electronically from one computer to another over a mesh without having to be read, re graphic symbold or printed. The information transferred mustiness have a defined structure concur between your company, and the company or group you send and receive information from. Any company or group which uses EDI is called a TRADING PARTNER.Examples of current uses of EDI includes semiautomatic teller machines (ATMs) in banks where EDI is used for transferring and withdrawing bills between different bank accounts, air hose reservation systems, stock flip legal proceeding and car reservation systems. USE OF EDI The entropy from one computer is normally not in a form suitable to be entered straight into another computer. The entropy may have to be logical differently before it idler be entered into another computer or almost items of data may not be needed at all. With EDI, all the data is converted unto an agreed warning format before it is sent over the network.The computer that receives the data can thence perpetrate the information it requires. Using EDI implies three things 1. instruction is transferred electronically rather than on paper. This means that there is no need to enter the data manually in the end computer. 2. Information is transferred between trade abetter _or_ abettor in crimes who have negotiated handicraft 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 contagious disease control mechanisms.ADVANTAGES OF EDI OVER A PAPER-BASED DOCUMENT TRANSFER SYSTEM This section highlights the advantages EDI has over a tralatitious paper-based memorandum transfer system. In a Paper-based remains ? A software finish generates a paper document on a form. ? Copies of the document are made. to a greater extent or less are passed to subjective departments to be filled, other copies are sent to the calling partner via the postal service. ? The traffic partner receives the document and retypes the information on the form into their computer. This retyping ofttimes introduces errors. The trading partner generates a paper ack presentlyledgement and this is sent to the originating company. The transfer of documents in a paper-based system could take a considerable length of time. In an EDI System ? The exertions programme program generates a stick, which contains the bear upon document. ? The document is converted to an agreed standard format. ? The register containing the document is sent electronically over the network. This network links the originating company and its trading partner. ? The accuse containing the document arrives at the trading partner.It is translated into the correct format and transferred to the recipients industry. ? 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 brief period of time and with no humankind intervention. HOW EDI WORKS? Regardless of the format chosen, companies employ EDI communicate with their trading partners in one of two ways Either they replacement data with several trading partners directly or they interact with multiple companies by dint of a central information clearing-house.In the latter(prenominal) case, all transactions are funneled finished a third partys computer system, which routes them to the inhibit receivers computer. This enables the transmitter to communicate with an unlimited lean of trading partners without worrying about proprietary systems, audit trails, variable transmitting velocitys, and widely distributed computer compatibility. Basically, here is how EDI works 1. previous to any computer work, representatives of two companies elicit in exchanging data electronically interpret to specify the applications in the EDI standard, which they will implement. 2.Each company adds EDI programs to its computer to translate company data in standard formats for transmission system, and for the reverse definition on the data it receives. 3. Then, as a great deal as operationally requires the two companies exchange data electronically in the standard formats. The data convey originates from records in the senders database subsequently 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 means to a computer record to be graceful and used essentially.All transmissions are checked two electronically and functionally and the protocol includes procedures for error detection and correction. INFORMATION FLOW IN EDI 1. A Company collects data for its own operational or statistical requir ements. 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 togs, and transmitted to the company or organization 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 consort 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 center is transmitted to the original sender to ack straight offledge the transmission and to identify any errors detected. . The receiver processes the information received harmonize to its own immanent procedures and timing requirements. EDI COMPONENTS A typical EDI system implements a specialised set of EDI by enabling the exchange of business documents. It accepts documents from business software applications, converts 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.There are EDI application programs for software developers to tack EDI to work with the various user application software programs. There is normally no end-user interaction with EDIit is entirely within the basis 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 contour programs under the purview of EDI. There are three main components in an EDI system 1. industry service- Providers the means of integrating quick or new applications into the EDI system. 2. transformation swear out-Converts data from ingrained format standards to an away format and translates data from an foreign format to an cozy format standard. 3. dialogue suffice-Passes documents into a network via the agreed communication protocol.Internal format transmitting Tranmission TRADING cross-data tears institutionalizes files PARTNER Documents coverTranmission communion Business suffice assist inspection and repair masking shoot TYPES EDI creates the next files as a document passes through and through the system ? Internal Format saddle (IFF) ? External Format buck (EFF) ? contagion 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 primarily for EDIs own use. External Format File The outer format file (EFF) contains the resembling data as the internal format file translated into the appropriate standard document format. Transmission File A transmission file contains one or more documents for the alike 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.

The following sections maintain an overview of what happens in each of three services. operation run 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 either intra-company or to external companies, i. e. , trading partners. The EDI Application Service holds each incoming and outperform document as a single internal format file. EDI converts the document to a standard format and sends it to the trading partner utilise 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 surpass 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 fi le to the definition Service. For incoming documents ? The Application Service receives an internal format file from the shift 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 emcee Internal Formal File due 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 communicating Service. For incoming documents ? The Translation Service 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 victimization a third-party service called a look on Added Network (VAN). The following lists describe what happens in the Communication S ervice 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 identify the type of connection to be used for this trading partner t determines which access 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. interior(a) 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 at electron speed. So it is a time sparing process and also low cost as compared with telephone system. level(p) though there are more advantages with EDI there are some disadvantages also. To feed the data into computer, work is compulsory. By compare with computer speed human speed is a bottleneck.And also errors may materialize at the time of data feeding. These errors can change the managerial decisions. Another chore 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 set in these cases. So in t hese case we cant use EDI system. &8212&8212&8212&8212&8212&8212&8212 FILE master of ceremonies due ROUTINES MANAGEMENT interface FILE SERVER C TFB T TFS MANAGEMENT INTERFACE
