One can transfer data from one database to the other and this is called importing and linking. When importing, one can select the object he or she wants to copy and can control tables being imported and specify the relationship of tables if it would also be transferred.
<span>Before you start creating a database, you should first use paper to plan, test, and revise. True or False?
TRUE</span>
Answer:
The answer is "Option b".
Explanation:
In the project of IEEE-754 to define 64 -bit we require a REAL8 double precision that is equal to 8 bytes and 64 bit, and it is also used for floating-point arithmetic, and other options were not correct that can be described as follows:
- In option a, REAL4 is used to define 32-bit, that's why it is not correct.
- In option c, This type of declaration is not valid in IEEE, that's why it is wrong.
- In option d, The REAL is a keyword that is used to define a value but in this, there is no value to define, that's why it is wrong.
Answer: Online analytical processing
Explanation:
Online analytical processing(OLAP) is the method through which multi-dimension analytical queries can be resolved.User can attain selected query data as per their selection and then assess and analyze them from different view point.
- It helps in viewing and reporting , planning ,performing analytical calculation, collecting data in data cubes etc.
- Other options are incorrect because data adjacency, Ad hoc reporting ,data segregation and E-discovery are not the mechanism through which query and storage of data in data cubes take place.
- Thus, the correct option is online analytical processing
