What is the difference between EDI and email?
In general, Internet and EDI are similar, but they are not exactly the same. Under high-secure protection, EDI Van converts companies’ data into an agreed format through access in a set of protocol type. Digital certificate for verification is also required in EDI services. Therefore, EDI services prevent bulk mails and virus data which occur in the email delivery.
EDIFACT (a.k.a. UN/CEFACT)
This is a United-Nations sanctioned file format. It encompases many different message types, relating to all sorts of business transactions and there are many different versions of the messages. Stylus Studio® loves to parse EDIFACT files. It fully supports all message types in all versions from D93A to D05A, using a native adapter that is just a comfortable going from EDIFACT to XML as to the reverse.
This is another EDI standard, governed by a group named ASC and whose secretariat is a group named DISA, of which DataDirect Technologies is a member.
UN/EDIFACT stands for the United Nations rules for the Electronic Data Interchange for Administration, Commerce and Transport. They are a set of international standards, directories and guidelines for the electronic interchange of structured data, and, in particular, relate to trade in goods and services between independent computerized information systems (UN/EDIFACT Rapporteur's Team, 1990).
2.3.1 History and Origin
The UN/EDIFACT work on EDI standardization developed from the need for a common international standard for the electronic transmission of commercial data.
In 1971, SITPRO, the Simplification of Trade Procedures Board in Great Britain began work on common EDI standards for Europe. In 1974, the UK EDI syntax called Trade Data Interchange (TDI) was published and was first used by UK customs authorities. In 1975, the UN began to develop terms of reference for international EDI standardization. In 1979, the United National Guidelines for Trade Data Interchange (UN/GTDI) syntax, based on the TDI guidelines developed by SITPRO was published.
By this time, the ANSI X12 standards were in use in North America. The value of merging the two to develop an international EDI standard was recognized and work was initiated within the United Nations/Economic Commission for Europe (UN/ECE) to develop the international EDIFACT standards.
2.3.2 Organization of UN/EDIFACT
The ECE is one of five regional commissions established by the Economic and Social Council of the United Nations. It includes 34 member states from North America, Eastern Europe and Western Europe. Additionally, any member country of the United Nations which has an interest in a given subject may participate in UN/ECE meetings, and certain approved
intergovernmental and non-governmental international organizations may participate in specific committees. Note that the UN/ECE should not be confused with the Commission of the European Community (CEC) (UN/EDIFACT Rapporteurs' Team (1990).
International EDI standardization activity is centered around the UN/EDIFACT standards developed by the United Nations Working Party on Facilitation of International Trade Procedures (WP.4). The structure of this group is illustrated in Figure 2.2. Work is carried out by a number of subordinate and related bodies including the Group of Experts on Data Elements and Automatic Data Interchange (GE.1) and the Group of Experts on Procedures and Documentation (GE.2). There are also a number of working groups preparing message standards for specific commercial sectors such as:
• Materials Management
• Travel, Tourism & Leisure
Working Party 4 meets twice each year. The link between WP.4 and the EDIFACT Boards where the actual standards development takes place is the Rapporteurs who report the results reached within the various EDIFACT Boards to WP.4. There are regional EDIFACT Rapporteurs and associated infrastructures for North America, Western Europe, Eastern Europe, Japan & Singapore, and Australia/New Zealand and an EDIFACT Board for Africa was recently established. A group has also been established to develop multilingual terminology that would make it possible to implement UN/EDIFACT in languages other than English. The group will also work to establish procedures and translation of the various working documents.
Accredited Standards Committee (ASC X12)
ASC X12 is the ANSI Accredited Standards Committee charged with developing EDI standards for use in the United States. The committee develops standards to facilitate electronic interchange relating to such business transactions as order placement and processing, shipping and receiving, invoicing payment and cash application data. The work of ASC X12 is conducted primarily by a series of subcommittees and task groups whose recommendations are presented periodically to the full ASC X12 Committee for ratification (Data Interchange Standards Association, 1990).
The Data Interchange Standards Association (DISA) serves as the secretariat for ASC X12. DISA's activities include communicating with ANSI and the public on behalf of the ASC X12 committee, organizing X12 meetings and publishing the X12 standards. To obtain ASC X12 standards or further information on ASC X12 activities contact:
ASC X12 Secretariat
Data Interchange Association, Inc.
1800 Diagonal Road, Suite 355
Telephone: (703) 548-7005
Once a year, DISA publishes the entire set of X12 standards in a single volume, called a release. This includes revisions of previously published standards, as well as new draft standards approved by ASC X12 during the year (referred to as Draft Standards for Trial Use). Releases are not considered American National Standards until they have undergone the ANSI-required public review process. ASC X12 uses the releases in order to make the approved draft standard available to users on a more frequent schedule. The Draft Standards for Trial Use are reviewed by ANSI every three years. Once approved they are adopted as American National Standards.
There are three major sets of EDI standards. UN/EDIFACT is the only international standard (infact, a United Nations recommendation) and is predominant in all areas out side of North America. ANSI ASC X12 and Uniform Communication Standard (UCS) are popular in North America and are very similar to each other.
What is the difference between an Information Exchange mailbox and an EDI mailbox?
Information Exchange , which is the mailbox feature of EDI Services, is one example of an EDI mailbox. An EDI mailbox is simply an electronic mailbox that can send and receive EDI data. Information Exchange can send and receive both EDI and non-EDI data. You can have multiple mailboxes on Information Exchange.
