Consider the given schemes:
Branch scheme = (Branch name, assets, branch city)
Customer scheme = (Customer name, street, Customer city)
Deposit scheme = (Branch name, account name, customer name, balance)
Borrow scheme = (Branch name, loan number, customer name, amount)
Client scheme = (Customer name, banker name)
Using the relational algebra the query that finds customers who have a balance of over 1000 is
  • a)
    π customer name (σ balance >1000(Deposits)
  • b)
    σ customer name (σ balance >1000(Deposits)
  • c)
    π customer name (σ balance >1000(Borrow)
  • d)
    σ customer name (σ balance >1000(Borrow)
Correct answer is option 'A'. Can you explain this answer?

The SQL statement is:
Select customer name from deposit where (balance > 1000)
∴ Relational algebra query is:
π customer name (σ balance > 1000(Deposits))
where π refers to select and σ specifies the condition that balance should not be greater than 1000.
