SM communities may provide better and faster problem solutions to complex supply chain problems. Social media is designed to foster content creation and feedback among networks of users, and that characteristic facilitates the iteration and feedback needed for problem solving. Companies whose profitability depends on the efficiency of their supply chain have long used information systems to improve both the effectiveness and efficiency of structured supply chain processes. Because supply chains are tightly integrated into structured manufacturing processes, there is less tolerance for the unpredictability of dynamic, adaptive processes. Solving problems is an exception; social media can be used to provide numerous solution ideas and rapid evaluation of them.

Methods of highlighting include: Blinking and audible tones, Color differences, Intensity differences, Size differences, Font differences, Reverse video, Boxing, Underlining, All capital letters, Offsetting the position of nonstandard information. Highlighting should be used to enhance user experience not be a distraction. In general, highlighting should be used sparingly to draw the user to or away from certain information and to group together certain information. There are several situations when highlighting can be a valuable technique for conveying special information:
• Notifying users of errors in data entry or processing;
• Providing warnings to users regarding possible problems such as unusual data values or an unavailable device
• Drawing attention to keywords, commands, high-priority messages, and data that have changed or gone outside normal operating ranges.
A general guideline resulting from this research is that highlighting should be used conservatively. Once a response is made, these highlights should be turned off. Additionally, highlighting methods should be consistently used and selected based upon the level of importance of the emphasized information.

Inter-enterprise information systems are information systems that are shared by two or
more independent organizations. Such systems typically involve thousands of users, and
solutions to problems require cooperation among different, usually independently owned,
organizations. Problems are resolved by meeting, contract, and sometimes by litigation. Because
of the wide span, complexity, and multiple companies involved, such systems can be
exceedingly difficult to change. The interaction of independently owned and operated
information systems is required.

Answer 34

It is not uncommon for a table that is returned as the result of a data manipulation operation, such as a query, to contain duplicate rows. This is often tolerated because of the processing time necessary for the DBMS to search the table to find and eliminate duplicate rows. This is especially true if the table is very large. In these cases, it is often acceptable to allow the duplicate rows to exist.

A trigger, once written and compiled, sits silently on the database server waiting for an event to happen. It is usually tied to one table and some action, such as insert, update or delete. Conversely, a routine has to be called even though it resides on the database server. It may access one, many or no tables in order to produce the desired results.

The HAVING clause and the WHERE clause differ in that the WHERE clause is used to identify rows that satisfy a stated condition. The HAVING clause is used to identify groups which have been created by the GROUP BY clause and that satisfy a stated condition. In cases when the WHERE clause and the HAVING clause are both allowed to appear in the same SELECT statement, the WHERE clause is generally implemented to execute before the HAVING clause.

Student answers will vary, but should include an understanding that the customer's operating system and browser interact technologically with a website and might be relevant in data analysis. An example is: Customer OSs and browsers could help a company determine what technical functionalities could be used in the site. For example, if it found out that a significant percentage of its users are using mobile browsers, they might want to make sure that the website is easily used by various mobile devices. Secondly, this data might be relevant in data mining or other analysis. For example, a retail clothing company might find that a significant portion of their most valued customers use an Apple operating system, and from other data analysis know that Apple users are more likely to purchase cashmere sweaters. Then the company may want to place a greater emphasis on selling the cashmere sweaters.

Answer 51

Update anomalies occur when you have to update the same data in several different spots. If a customer, for instance, has several different kinds of accounts, and their contact information is stored in separate tables for each of those accounts, then any change in their contact information would have to be updated in each of those accounts. This greatly increases the chance of mistakes in entry and inconsistent information.
