Explanation:

When typing, you rest your right pointer finger on the J key.

Most people are able to find this key without looking due to a small bump on the lower half of it.

Having your finger rest here allows for your hands to each take up roughly one half of the keyboard.

Como hace décadas, se crearon grandes y muy pesados, ¡casi como una computadora! Pero luego se hizo cada vez más pequeño, a medida que encontraron formas de fabricarlo. Se ha desarrollado rápidamente en las últimas décadas, por lo que casi parece posible que suceda cualquier cosa.Hay tantas evoluciones de teléfonos celulares porque les da la oportunidad de desarrollarse aún más a través de generaciones y también de mejorarlo, por lo que es más asequible, cómodo y con funciones más avanzadas.

Cell phones have been such an advance to us of a late. It has become such a useful thing in our lives, that we can't even think of living without it.  It first started off very plain, but over time, features were added, like, Emails, Voice Mails, Photos, Videos, the Internet, and the Web. As decades ago, they were created big and very heavy, almost like a computer! But, then it became smaller and smaller, as they found ways to manufacture it. It has developed for fast in the past decades, that it almost seems possible for anything to happen.

Treston, an automobile manufacturer, has recently implemented a new database system. It is confident that this system will help enhance the company's internal (employees) and external (customers and channel partners) communication. Treston is planning to pursue a just-in-time inventory system soon after the database system is implemented. After the implementation of the database system, however, Treston realized that the database system was not effective. Which of the following, if true, can be cited as a reason for the failure of Treston's database system?
A. Microsoft launched a new version of Enterprise Microsoft Access which is better than Treston's database system.
B. The maintenance cost of Treston's new database system was less than the one it was previously using.
C. Treston's new database system was not supported by the database system of its suppliers and distributors.
D. Treston's competitors implemented its database a few days prior to Treston's implementation date.
E. Treston had internally trained personnel managing its new database system, keeping costs low.

________ are produced at predefined intervals to support routine decisions.
A. Ad hoc queries
B. Exception reports
C. Drill-down reports
D. Scheduled reports
E. Key-indicator reports

________ help analyze why a key indicator is not at an appropriate level or why an exception occurred.
A. Ad hoc queries
B. Exception reports
C. Drill-down reports
D. Scheduled reports
E. Key-indicator reports

Answers

Answer:

C. The New database system of Treston was not supported by the database system of its suppliers and distributors.

TRUE

False

Scheduled reports

Drill down reports

Explanation:

The just-in-time is popularly known as the JIT. The JIT inventory system is defined as a management strategy in which the company gets goods and products as close as when they are actually needed. Some goods are received 'just in time' at the processing or at the manufacturing time of the final product.

In the context, the data base system failed for Treston company as the new data base system did not support the database system for the suppliers as well as the distributors of the car manufacturing company, Treston.

It is true that by combining the intelligence of human and the reasoning capabilities with that of retrieval and the analysis of the technology, the visual analytics can help in the process of decision making.

In the distributed environment done online, performing the real-time analytical processes does not enhances the performance of the transaction processing. So the answer is false.

A scheduled report is a report that is sent out or delivered at a specified time by an email provider. They are produced to support the routine decisions at predefined intervals.

A Drill down reports helps to see the data for a more detailed and a comprehensive view. It helps to analyze that a key indicator is not the appropriate level.
