Which of the following is not a relational algebra function? Explanation: There does not exist any operation named as manipulate operation in relational algebra. The union gives the union of two sets. Project is similar to select in SQL and select is similar to where in SQL.
Which of the following is not a relational opeartor in Python? Explanation: = is not considered as a relational operator in Python.
In this question, & is not a logical operator and && represents the logical AND operator, || represents an OR logical operator and ! represents NOT logical operator.
| Operator | Meaning | Example |
|---|---|---|
| > | Greater Than | 3 > 5 gives us false |
| < | Less Than | 3 < 5 gives us true |
| >= | Greater Than or Equal To | 3 >= 5 give us false |
| <= | Less Than or Equal To | 3 <= 5 gives us true |
! is a NOT operator. So, '&' is not a Logical operator.
What is a relational operator Python?
Relational operators in Python are also called as Comparison operators. They are used to compare the operands on either side and determine the relation between them. The output of the comparison results in a Boolean value.

| < | Less Than | 3 < 5 returns true |
| >= | Greater Than or Equal To | 3 >= 5 returns false |
Boolean operators are specific words and symbols that you can use to expand or narrow your search parameters when using a database or search engine. The most common Boolean operators are AND, OR, NOT or AND NOT, quotation marks “”, parentheses (), and asterisks *.
There are six common relational operators that give a Boolean value by comparing (showing the relationship) between two operands.
2) Non-relational databases, also called NoSQL databases, the most popular being MongoDB, DocumentDB, Cassandra, Coachbase, HBase, Redis, and Neo4j. These databases are usually grouped into four categories: Key-value stores, Graph stores, Column stores, and Document stores (see Types of NoSQL databases).
Which among the following is NOT a logical or relational operator? Explanation: None.
Relational operators are also called as Comparison operators. Relational operators in python are : >, <, ==, != , >=, <=. Greater than returns true when left operand is greater than the right operand.
The correct answer is Microsoft Outlook. Microsoft SQL Server is a relational database management system developed by Microsoft. MySQL Database Service is a fully managed database service to deploy cloud-native applications.
Which of the following is a fundamental operation in relational algebra? Explanation: The fundamental operations are select, project, union, set difference, Cartesian product, and rename. 3.
D) File Database is not a type of database.
What are the 6 Relational operators in Python?
We have six of these, including and limited to- less than, greater than, less than or equal to, greater than or equal to, equal to, and not equal to. So, let's begin with the Python Comparison operators.

Relational Operators in Python.
| Operator | Description | Syntax |
|---|---|---|
| != | Not equal to – True if operands are not equal | x != y |
There are five logical operator symbols: tilde, dot, wedge, horseshoe, and triple bar. Tilde is the symbol for negation. The word “not” and the phrase “it is not the case that” are used to deny the statement that follows them (we refer to their use as “negation”).
The NOT logical operator reverses the true/false outcome of the expression that immediately follows. The NOT operator affects only the expression that immediately follows, unless a more complex logical expression is enclosed in parentheses. You can substitute ~ or ¬ for NOT as a logical operator.
Answer. D. || is logical OR operator.
In C++, there are six relational operators.
Which of the following is not an operator in C? Explanation: None.
| Operator | Example | Meaning |
|---|---|---|
| && | expression1 && expression2 | Logical AND. True only if all the operands are true. |
| || | expression1 || expression2 | Logical OR. True if at least one of the operands is true. |
| ! | !expression | Logical NOT. True only if the operand is false. |
Explanation : Option A is not a relational operator, it is a logical operator. Relational operators are >, <, >=, <=, ==, !=
...
Identity operators.
| Operator | Meaning | Example |
|---|---|---|
| is not | True if the operands are not identical (do not refer to the same object) | x is not True |
What is relational operator in Java?
Relational Operators in Java are used to comparing two variables for equality, non-equality, greater than, less than, etc. Java relational operator always returns a boolean value - true or false.
There are three logical operators: and , or , and not . The semantics (meaning) of these operators is similar to their meaning in English.
1. What is the output of relational operators? Explanation: None.
In computer science, a relational operator is a programming language construct or operator that tests or defines some kind of relation between two entities. These include numerical equality (e.g., 5 = 5) and inequalities (e.g., 4 ≥ 3).
Intersect. Register now or log in to answer. Option C. Join is not a Boolean Operation.
The three basic boolean operators are: AND, OR, and NOT.
| Operator | Description | Example |
|---|---|---|
| && (logical and) | Called Logical AND operator. If both the operands are non-zero, then the condition becomes true. | (A && B) is false |
| || (logical or) | Called Logical OR Operator. If any of the two operands are non-zero, then the condition becomes true. | (A || B) is true |
"Option A: '>' is a relational operator".
The Relational operators are used for making a comparison of the value of one operand with another operand. The relational operators are: ==, >, <, != , >=, <=. Option B: AND is the logical operator.
There are three types of operator that programmers use: arithmetic operators. relational operators. logical operators.
There are types of operators like arithmetic, logical, conditional, relational, bitwise, assignment operators etc. Some special types of operators are also present in C like sizeof(), Pointer operator, Reference operator etc.
What is relational operator with example?
...
Relational Operators.
| Operator | Relation | Example |
|---|---|---|
| EQ or = | Equality | X = Y |
| NE or # | Inequality | X # Y |
| >< or <> | Inequality | X <> Y |
| LT or < | Less than | X < Y |
The operators !, &&, and || are called relational operators. You can disable assert statements by using which of the following? Which of the following will cause a logical error if you are attempting to compare x to 5?
Java Relational Operators
Here, < operator is the relational operator. It checks if a is less than b or not. It returns either true or false .
The “=” is an assignment operator is used to assign the value on the right to the variable on the left. The '==' operator checks whether the two given operands are equal or not. If so, it returns true.
| Operator | Meaning | Example |
|---|---|---|
| > | Greater Than | 3 > 5 gives us false |
| < | Less Than | 3 < 5 gives us true |
| >= | Greater Than or Equal To | 3 >= 5 give us false |
| <= | Less Than or Equal To | 3 <= 5 gives us true |
Which of the following is not an operator in C? Explanation: None.
Operator. The “not” logical operator is used to convert a value from true to false, or from false to true. Similarly, if an operand evaluates to true, a logical “not” would cause it to evaluate to false.
