The correct answer: Data independence
Data independence<span> is the type of </span>data<span> transparency that matters for a centralised DBMS. It refers to the immunity of user applications to changes made in the definition and organization of </span>data<span>. Physical </span>data independence<span> deals with hiding the details of the storage structure from user applications.
</span>
The logical<span> structure of the data is known as the 'schema definition'. In general, if a user application operates on a subset of the </span>attributes<span> of a </span>relation<span>, it should not be affected later when new attributes are added to the same relation. Logical data independence indicates that the conceptual schema can be changed without affecting the existing schemas.
</span>
<span>The physical structure of the data is referred to as "physical data description". Physical data independence deals with hiding the details of the storage structure from user applications. The application should not be involved with these issues since, conceptually, there is no difference in the operations carried out against the data.</span>
Answer:
the first argument listed after IF
Explanation:
The Logical... argument in an IF function formula is always the first argument listed after IF. And the second option is the value to be printed if the logical...argument is true, and if it is false then the value mentioned as third argument is assigned, or printed. And the logical...argument never comes before the IF function formula. Hence, the right option is the first argument.
Answer:
How to convert binary to decimal ?
It consists of digits from 0 to 9. Binary to decimal conversion can be done in the simplest way by adding the products of each binary digit with its weight (which is of the form - binary digit × 2 raised to a power of the position of the digit) starting from the right-most digit which has a weight of 20.
what is digital and analogue?
In analog technology, a wave is recorded or used in its original form. So, for example, in an analog tape recorder, a signal is taken straight from the microphone and laid onto tape.In digital technology, the analog wave is sampled at some interval, and then turned into numbers that are stored in the digital device.
