Answer:
The answer is "Option A".
Explanation:
The program to the given question can be given as:
program:
var1 = "Happy" #defining variable var1
var2= "Birthday" #defining variable var2
var3 = (var1+var2) *2 #defining variable var3 and calculate value
print (var3) #print value.
Output:
HappyBirthdayHappyBirthday
In the above python program, three variable is defined, that is var1, var2, and var3, in which variable var1 and var2 we assign a value, that is "Happy" and "Birthday".
In variable var3 we add the value of var1 and var2 variable and multiply by 2. It will print the variable value two times. and other options are not correct that can be defined as:
- In option B and C, Both variable var1 and var2 print there values two times but in option B var1 value print two time and var2 value print one time only and option C var1 variable value is print only one time and var2 variable value is print two times that's why it is not correct.
- In option C, Both variable var1 and var2 print there values two times that's why it is not correct.
It is true. RDBMS enforce integrity rules automatically. Integrity rules are automatically enforced by RDBMSs.
Integrity rules are automatically enforced by RDBMSs. Because it contains the design choices made regarding tables and their structures, a data dictionary is frequently referred to as "the database designer's database." Any character or symbol intended for mathematical manipulation may be contained in character data.
Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of RDBMS. Each table row in a relational database is a record with a distinct ID known as the key.
It is simple to determine the associations between data points because the table's columns carry the properties of the data and each record typically has a value for each property.

A byte is a sequence of 8 bits (enough to represent one alphanumeric character) processed as a single unit of information. A single letter or character would use one byte of memory (8 bits), two characters would use two bytes (16 bits).
