This paper introduces EDI, describes the various components of an EDI format, and discusses how it is applied to technology. EDI is how companies can-standardize a way to exchange the electronic form of business data among organizations. EDI, in turn, replaces postal mail, fax, and email to connect directly to business partners' computers. In order to effectively implement and utilize this technology, a person should understand the structure of an EDI document.
EDI root element
In EDI, the root is where any EDI message would start from. This would be similar to the root in an XML document and would represent the start of the transaction set or message. The root element identifies the type of EDI transaction being executed, such as an invoice, purchase order, or shipment notice. It sets the standard for the structure and dictates the order in which the segments and elements appear.
The Group
In the syntax of EDI, the group is a logical grouping of transaction sets or messages. It acts as a wrapper that wraps different types of transactions that pertain to a certain business process or trading partner. For example, a group can have all different types of transaction sets for a certain trading partner or all of one type of transaction, such as invoices, for a certain period of time.
The Segment
The segments are the building blocks of an EDI transaction set or message. A segment is a group of related data elements that appear together to convey a specific piece of information. For example, a segment may contain all the information pertaining to a ship-to address or details about a line item on an invoice. Segments begin with a segment identifier, usually composed of two or three letters, followed by data elements, separated from each other by a delimiter.
A Composite
In EDI, a composite refers to when multiple related data elements are taken as a whole to represent a more complex structure or concept. Composites occur within segments. They will be separated by composite element separator. A typical example of a composite data element would be the quantity of a product and the unit of measure .
An Element
An element is the smallest named unit of information in an EDI document. It is a single unit of data, which can be a price, date, quantity, or identifier. Elements fill the segments and composites to give the EDI message content and detail. Each element has a specific data type
which may be numeric, alphanumeric, or date, and is imperative to ensure that the meaning in the EDI transaction is clearly interpreted by the receiving party.
Conclusion
Knowledge of EDI format structures plays a significant role in companies involved in electronic data interchange. The EDI root provides an idea about the setting of a transaction, while groups bring related sets of transactions together. The segments serve as the primary structural components. Composites and elements are nested in them to give a version with great detail of the information being transmitted. Composites come as an assembly of related elements, through which complex data is conveyed, while elements themselves are the small units of granular data. Since EDI messaging has to be done quickly and without mistakes, this calls for the mastering of these component parts, as this is the backbone of most modern electronic business transactions. These formats allow structuring the data exchange within organizations to be accurate, fast, and consistent in all types of business communications.
