Question
Chapter 7, Problem 43E
Program Plan Intro
Materialized view:
- Materialized view is a
database object that contains the result of a query. - It is mainly used for increasing application performance.
- It is used for replicating data and to cache expensive queries in a data warehouse environment.
</PROGRAM-PLAN-INNTRO>
Constraints on materialized views enforcing functional dependency:
- The constraints on materialized view helps for increasing execution speed.
- Materialized view is refreshed by the type of materialized view.
- The constraints under materialized view should be normalized.
- That means each dimension should be contained in one table.
- Also, the joins between tables must be normalized or partially normalized.
- Hence, there is a guarantee that each child side row joins with exactly one parent side row.
- Hence, constraints on materialized view can be used for enforcing functional dependency.

Write a C program using embedded assembler in which you use your own function to multiply by two without using the product.
Tip: Just remember that multiplying by two in binary means shifting the number one place to the left. You can use the sample program from the previous exercise as a basis, which increments a variable. Just replace the INC instruction with SHL.
