Question

Explanation:

Answer 2

Answer:

The set of data values or attributes for a particular type where it has one value for one row (in a database table with rows and columns).

Explanation:

In a relational database, there are rows and columns in a table. The values in these rows or columns can contain values, numbers or pointers to other files, images, or documents. A column is associated with unique name for reference, content and time stamp to determine the validity of the content.

Example:

{  

city :{ name : “name”, value : “Bengaluru“, timestamp : 123456789}

}

Whenever the columns are added, sorting happens simultaneously. There is no way to sort columns after they are added.
