Code Explanation: Conditional Statement

The provided code snippet implements a conditional logic structure typically used in programming languages such as SQL, DAX, or similar query languages. The code evaluates the values of Quantity and Price to categorize each case into "High Value," "Medium Value," or "Low Value".

Code Structure

Code Snippet

if [Quantity] > 10 and [Price] > 100 then "High Value"
else if [Quantity] > 10 or [Price] > 100 then "Medium Value"
else "Low Value"

Breakdown of Components

1. Conditional Logic: The code consists of a series of conditional checks that determine which category a given item falls into based on its Quantity and Price.

2. Conditions:

   • First Condition: if [Quantity] > 10 and [Price] > 100

     • Purpose: This checks whether both Quantity exceeds 10 and Price exceeds 100.
     • Result: If true, it returns "High Value".

   • Second Condition: else if [Quantity] > 10 or [Price] > 100

     • Purpose: This checks whether either Quantity exceeds 10 or Price exceeds 100.
     • Result: If true, it returns "Medium Value".

3. Default Case:

   • else "Low Value"
   • Purpose: This is the fallback option that is executed if neither of the above conditions are met.
   • Result: If none of the previous conditions are satisfied, it returns "Low Value".

Evaluation of Logic

• The logic adheres to standard programming practices for decision-making, enabling the categorization of items based on their properties.
• The use of and implies that both conditions must be satisfied for "High Value." Conversely, using or allows for more flexibility in the determination of "Medium Value."

Key Concepts Explained

• Conditional Statements: These are fundamental programming constructs that allow for branching logic, enabling different execution paths based on varying input conditions.
• Logical Operators:
  • and: Both conditions must be true.
  • or: At least one of the conditions must be true.

Additional Example

To illustrate the use of conditional statements in a different context, consider a similar scenario with different threshold values:

if [Sales] > 5000 and [Returns] < 100 then "High Performance"
else if [Sales] > 5000 or [Returns] < 100 then "Moderate Performance"
else "Low Performance"

Explanation of the Example

• High Performance: This condition checks for high sales and low returns.
• Moderate Performance: This condition checks for either high sales or low returns.
• Low Performance: This is the fallback option for items that do not meet the conditions for high or moderate performance.

Conclusion

The provided code snippet is a well-structured conditional statement that classifies items based on their quantity and price. Understanding the use of conditional logic and logical operators is essential for effective programming and data categorization.
