ASCII:
American Standard Code for Information Interchange
Conditional
(C):
A data element requirement designator which indicates the presence
of other data elements in the segment. The condition must be stated
and must be computer process able.
Data Element:
The basic units of information in the EDI standards containing a
set of values that represent a singular fact. They may be single
character codes, literal descriptions or numeric values. EXAMPLE:
"PURCHASE-ORDER-NUMBER."
Data Element
Delimiter:
The single character delimiter follows the segment identifier and
each data element in a segment except the last.
Data
Element Length:
This is the range, minimum to maximum, or the number of character
positions available to represent the value of the data element.
A data element may be of variable length with the range from minimum
to maximum, or it may be of fixed length in which the minimum is
equal to the maximum.
Data Element Reference Number:
Unique identifier assigned to each data element.
Data
Element Requirement Designator:
A code defining the need for a data element value to appear in the
segment if the segment is transmitted. The codes are Mandatory (M),
Optional (O) or Conditional (C).
Data Element Type:
A data element may be one of six types: numeric, decimal, identifier,
string, date or time.
Delimiters:
The delimiters consist of two levels of separators and a terminator.
The delimiters are an integral part of the transferred data stream.
Delimiters are specified in the interchange header and may not be
used in a data element value elsewhere in the interchange.
DISA:
Data Interchange Standards Association. A non-profit organization
funded by X12 which serves as the secretariat for X12.
Document:
The data that makes up a business transaction, such as an invoice,
purchase order or ship notice.
EDI:
Electronic Data Interchange is the computer-to-computer exchange
of business-related documents in a structured, machine processable
format.
EDIFACT:
EDI for Administration, Commerce and Transport.
Functional
Acknowledgment:
Notification to the sender that an electronic document has been
received in a standards-compliant format.
Functional
Group:
Electronic documents (transaction sets) of like type, destined for
the same trading partner.
Gateway:
A connection between two networks which allows messages to be routed
from one to the other. A communications interface between one system
and another.
ISO:
International Standards Organization responsible for defining international
standards.
LOOP:
A group of semantically related segments; these segments may be
either bounded or unbounded (X12.6). EXAMPLE: The N1 loop, which
indicated segments N1 to PER for name and address information.
Mailbox:
An electronic data storage location within a network service which
is set aside for a specific user to hold messages.
Mandatory
(M):
A data element/segment requirement designator which indicates the
presence of a specified date element is required.
Max
Use:
The maximum number of times that a segment can be used at the location
in a transaction set.
Mapping:
Utilizing a set a rules to convert data from one format to another.
Optional (O):
A data element/segment requirement designator which indicates the
presence of a specified data element/segment is at the option of
the ending party. Its use may be based on the mutual agreement of
the interchange parties.
Qualifier:
A data element which identifies or defines a related element, set
of elements or a segment. The qualifier contains a code taken from
a list of approved codes.
Repeating Segment
A segment that may be used more than once at a given location in
a transaction set.
Segment:
Logically grouped data, usually an electronic representation of
a "line" on a printed business document. A data segment
consists of a segment identifier, one or more data elements, each
preceded by an element separator and ending with a segment terminator
(X12.6).
Segment Directory:
X12.22 provides the purposes and formats of the segments used in
the construction of transaction sets. The directory lists each segment
by name, purpose, identifier, the contained data elements in the
specified order and the requirement designator for each data element.
Segment Identifier:
A unique identifier for a segment composed of a combination of two
or three uppercase letters and digits. The segment identifier occupies
the first character positions of the segment. The segment identifier
is not a data element.
Segment Terminator:
A unique character appearing at the end of a segment to indicate
the termination of the segment.
Syntax:
The grammar or rules which define the structure of the EDI standards
(i.e. the use of loops, qualifier, etc.). Syntax rules are published
in ANSI X12.6.
Trading Partner:
A supplier, customer subsidiary or any other organization with which
it does business.
Translator:
Software package which converts the EDI document into a file which
the receiving computer system can understand.
Transaction
Set:
A type of electronic business document defined in standard syntax
which consists of a transaction set header segment, one or more
segments in a specified order and a transaction set trailer segment.
Transaction Set ID:
An identifier that uniquely defines the transaction set. This identifier
is the first data element of the transaction set header segment.
Translation:
The act of accepting documents in other than X12 standard format
and translating them to the X12 standard format.
VAN:
Value Added Network. A public data communications network offering
EDI-specific services such as standards-compliance checking.
X.25:
International standard for packet switching.
