Which of the following is a correct statement regarding volume-based value?
The more data businesses have on the customers, both recent and historical, the greater the insights.
This answer is correct.

Which of the following characteristics distinguishes electronic data interchange (EDI) from other forms of electronic commerce?
.EDI transactions are formatted using standards that are uniform worldwide.
This answer is correct.
Organizations such as the American National Standards Institute (ANSI) have defined virtually every type of business transaction in terms of their fields and information content. These definitions are termed transmission sets. When a trading partner sends a transmission set, the receiving computer can expect to receive the specified information in a specified format.
Which one of the following is likely to be a concern in performing an assessment of an electronic data interchange (EDI) purchasing system?
Increased turnover of the information technology staff.
This answer is correct.
EDI systems rely on technically trained personnel for operations. Changes in personnel suggest that crucial expertise may have been lost.
All of the following are correct statements regarding big data except
Big data is an evolving term that describes any voluminous amount of structured data that has the potential to be mined for information.
This answer is correct.
Big data is an evolving term that describes any voluminous amount of structured, semi-structured, and unstructured data that has the potential to be mined for information. Thus, the statement is incorrect because big data includes semi-structured and unstructured data in addition to structured data.
Which of the following is not an advantage of business-to-business (B2B)?
Reduced information technology costs.
This answer is correct.
Instituting a B2B system requires large initial outlays for equipment, software, and training.
A digital signature is used primarily to determine that a message is
Unaltered in transmission.
This answer is correct.
A digital signature is a means of authenticating an electronic document, such as a purchase order, acceptance of a contract, or financial information. Because digital signatures use public-key encryption, they are a highly secure means of ensuring security over the Internet.
Organizations that move to implement EDI often use value-added networks (VANs). Which of the following would not normally be performed by a VAN?
Provide translations from clients’ computer applications to a standard protocol used for EDI communication.
This answer is correct.
Companies must purchase their own software to translate their data to a national standard protocol for EDI purposes, either ANSI X.12 in the U.S. or EDIFACT in Europe and most of the rest of the world. Once the data are in the standard format, the VAN handles all aspects of the communication. VANs are privately owned telecommunications carriers that sell capacity to outside users. Among other things, a VAN provides a mailbox service permitting EDI messages to be sent, sorted, and held until needed in the recipient’s computer system.
A research-based firm in the medical field could use each of the following Internet-based tools for collaboration except
Electronic data interchange.
This answer is correct.
Electronic data interchange is a method used specifically for carrying on business-to-business e-commerce. This would not be an important tool for collaboration in a research-based firm in the medical field.
