Answer:

once per month

Explanation:

The correct answer is - once per month

Reason -

Probability of 1 failure of 1000 hard disk = 750,000/1000 = 750 hrs

So,

750/24 = 31.25 days

⇒ approximately one in a month.

After you use the create sequence statement to create a sequence, you can use the NEXTVAL  pseudo column to get the next value in the sequence.

<h3 /><h3>How do you create a sequence?</h3>
  • You must have the Create any sequence system privilege to create a sequence in another user's schema.
  • Specify the schema that will hold the sequence.
  • If you leave out schema, Oracle Database will create the sequence in your own schema. Name the sequence that will be created.
  • Pseudo-columns allow selection, but you cannot edit, update, or remove their values.
  • A pseudo-column is analogous to a function that does not accept any inputs. This section goes over the two pseudo-columns, CURRVAL and NEXTVAL.
  • A pseudo column is a "column" that displays a value when a value is selected but is not one of the table's true columns.
  • Two examples are SysDate and RowID. It is frequently used in tandem with the DUAL table.
  • After you utilize the make sequence statement to make a sequence, you can utilize the NEXTVAL pseudo column to obtain the next value in the sequence.

Which of the following would be a show stopper for the development of an enterprise mobile app? The app demands data throughput
mestny [16]

Answer:

The cost of the app development is far greater than the tangible and intangible projected benefit of the app.

Explanation:

The first option is not correct, as in such cases, the app will be available in other areas. Also in case of a bad market share, it is not clear whether the app business will be profitable or not. And hence this is also not a correct option. However, the third option can be a show stopper, as it suggests the app business is not profitable, and no business or app developer is going to make such an app. And the fourth option is wrong, as some Governments will allow the app usage, and the app can still earn the profit. And hence, the correct option is as mentioned in the Answer section.
