Fast than the postal service Standards: document standards are the heart of EDI The role of standards: Every business has application files that are used to manipulate their data in ways that are familiar to the business. The problem is that most businesses, though using the same types of data, do not use the same application programs or hardware and software platforms. If businesses are to be able to communicate their data to one another, they must have a common ground to meet on to allow the exchange of the information. Standards are the solutions to this problem. All business that conform to specific standards can share data in the formats delineated by those standards. ANSI ASC X12: The American National Standards Institute's Accredited Standards Committee X12 (ANSI ASC X12) is the accepted standard for EDI transactions in the United States. The ANSI ASC X12 committee has the mandate to develop variable-length data formats for standard business transactions. The committee was accredited in 1980, and the X12 standard has been evolving ever since. One of the requirements placed on the committee was and is to keep the standard open to interindustry applications. This requirement makes the standard more complex than an industry-specific standard, but the advantages easily overcome the disadvantage of complexity. With a single standard, a business has multiple functionality and only has to use one standard for each business function. EDIFACT: The International Standards Organization (ISO), an organization within the United Nations, has developed the EDI standard that is used in Europe. The Electronic Document Interchange for Administration, Commerce, and Transportation (EDIFACT) is the UN standard that the whole world has agreed to eventually adopt. The actual implementation of EDIFACT within the U.S. has been moving at a snail's pace. The standard appears to currently be taking the same route that metric standards have taken. Everyone agrees that EDIFACT is the international standard, but tried and true X12 standards are not abandoned in favor of EDIFACT. Other document standards: Other document standards are in existence, most notably HL7, which is used by the hospital systems and is ANSI approved. 52 | P a g e Created By Created Date Category ViewPoint Modified Date Kris Durham Top of the Document
Security: One of the major roles that is provided by the data communications technology is the ability to apply security to EDI transactions so that the transactions will not be tampered with or observed, depending on the level of security needed. The security modules that are discussed in this section are depicted in figure 3.9 Confidentiality: Confidentiality requires that all communications between parties are restricted to the parties involved in the transaction.
