Q1. How would you optimize joins
Ans. 
Optimizing joins involves using indexes, reducing unnecessary columns, and using appropriate join types.
• Use indexes on columns used in join conditions to speed up the process.

• Avoid selecting unnecessary columns in the result set to reduce data transfer.

• Consider using appropriate join types like INNER JOIN, LEFT JOIN, or RIGHT JOIN based on the data relationships.

Q2. What are different Join strategies
Ans. 
Join strategies are methods used to combine data from multiple tables in a database.
• Common join strategies include inner join, outer join, left join, and right join.

• Inner join returns only the rows that have matching values in both tables.

• Outer join returns all rows from both tables and fills in NULL values for non-matching rows.

• Left join returns all rows from the left table and the matched rows from the right table.
