III. Explain in Brief Answer

Question 1.
Write a short note on EDI?
Answer:

1. The Electronic Data Interchange (EDI) is the exchange of business documents between one trade partner and another electronically.

• EDIFACT includes a set of internationally agreed standards, catalogs and guidelines for electronic exchange of structured data between independent computer systems.

Question 4.
Write a note on EDIFACT message?

IV. Explain in detail

Question 1.
Briefly explain various types of EDI?
Answer:
The types of EDI were constructed based on how EDI communication connections and the conversion were organized. Thus based on the medium used for transmitting EDI documents the following are the major EDI types.

1. Direct EDI
2. EDI via VAN
3. EDI via-FTP/VPN, SFTP, FTPS
4. Web EDI
5. Mobile EDI
6. Direct EDI/Point-to-Point

It is also called as Point-to-Point EDI. It establishes a direct connection between various business stakeholders and partners individually. This type of EDI suits to larger businesses with a lot of day to day business transactions.

EDI via VAN:
EDI via VAN (Value Added Network) is where EDI documents are transferred with the support of third party network service providers. Many businesses prefer this network model to protect them from the updating ongoing complexities of network technologies.

EDI via FTP/VPN, SFTP, FTPS:
When protocols like FTP/VPN, SFTP and FTPS are used for exchange of EDI based documents through the Internet or Intranet it is called as EDI via FTP/VPN, SFTP, FTPS.

Web EDI:
Web based EDI conducts EDI using an web browser via the Internet. Here the businesses are allowed to use any browser to transfer data to their business partners. Web based EDI is easy and convenient for small and medium organizations.

Mobile EDI:
When smartphones or other such handheld devices are used to transfer EDI documents it is called as mobile EDI. Mobile EDI applications considerably increase the speed of EDI transactions.

Question 2.
What are the advantages of EDI?
Answer:
Advantages of EDI:
EDI was developed to solve the problems inherent in paper-based transaction processing and in other forms of electronic communication. Implementing EDI system offers a company greater control over its supply chain and allow it to trade more effectively. It also increases productivity and promotes operational efficiency. The following are the other advantages of EDI.

1. Improving service to end users
2. Increasing productivity
3. Minimizing errors
4. Slashing response times
5. Automation of operations
6. Cutting costs
7. Integrating all business and trading partners
8. Providing information on process Status

EDI Layers:
Electronic data interchange architecture specifies four different layers namely;

1. Semantic layer
2. Standards translation layer
3. Transport layer
4. Physical layer

These EDI layers describes how data flows from one computer to another.

Question 3.
Write about structure of EDIFACT?
Answer:
EDIFACT Structure:
EDIFACT is a hierarchical structure where the top level is referred to as an interchange, and lower levels contain multiple messages. The messages consist of segments, which in turn consist of composites. The final iteration is a data element.

Segment Tables:
Segment table lists the message tags. It contains the tags, tag names, requirements designator and repetition field. The requirement designator may be mandatory (M) or conditional (C). The (M) denotes that the segment must appear at least once. The (C) denotes that the segment may be used if needed. e.g. C10 indicates repetitions of a segment or group between 0 and 10.

III. Explain in detail

Question 1.
Explain EDI standards?
Answer:
EDI Standards:

• The standard is the most critical part of the entire EDI. Since EDI is the data transmission and information exchange in the form of an agreed message format, it is important to develop a unified EDI standard.
• The EDI standard is mainly divided into the following aspects: basic standards, code-standards, message standards, document standards, management standards, application standards, communication standards and security standards.
• The first industry-specific EDI standard was the TDCC published by the Transportation Data coordinating Committee in 1975.
• Then other industries started developing unique standards based on their individual needs. E.g. WINS in the warehousing industry.
• Since the application of EDI has become more mature, the target of trading operations is often not limited to a single industry.
• In 1979, the American National Standards Institute Accredited Standard Committee (ANSI ASC) developed a wider range of EDI standard called ANSI XI2.
• On the other hand, the European region has also developed an integrated EDI standard. Known as GTDI (Guideline for Trade Data Interchange).
• ANSI X12 and GTDI have become the two regional EDI standards in North America and Europe respectively.
• After the development of the two major regional EDI standards and a few years after trial, the two standards began to integrate and conduct research and development of common EDI standards.
• Subsequently, the United Nations Economic Commission for Europe (UN/ECE/WP.4) hosted the task of the development of international EDI standards. In 1986, UN/EDIFACT is officially proposed. The most widely used EDI message standards are the United Nations EDIFACT and the ANSI X12.
