Normalization is the process of organizing data in a database while denormalization is the process of intentionally introducing redundancy into a database.

• Normalization is used to minimize data redundancy and improve data integrity.

• Denormalization is used to improve query performance by reducing the number of joins needed.

• Normalization involves breaking down a table into smaller tables and establishing relationships be...read more

Fibonacci series is a sequence of numbers where each number is the sum of the two preceding ones.

Shear stress is a type of stress that acts parallel to a surface, causing layers of material to slide past each other.

• Shear stress is caused by forces applied parallel to a surface, leading to deformation.

• It is calculated as force divided by the area over which the force is applied.

• Shear stress is commonly seen in materials like fluids, where layers move at different speeds.

• Examples include cutting paper with scissors,...read more

Categories of strength in machine design include static strength, fatigue strength, impact strength, and toughness.

• Static strength: Ability to withstand a constant load without breaking.

• Fatigue strength: Ability to withstand repeated loading over time.

• Impact strength: Ability to withstand sudden shocks or impacts.

• Toughness: Ability to absorb energy and deform without fracturing.
