Fundamentals of Datawarehouse

A data warehouse is a data repository which is used to store large quantities of historical data that are mostly used for creating reports that help businesses to identify their weaknesses and strengths. For example, demographics data about people of a region can help businesses identify the needs and preferences of the region’s population. A data warehouse acts as a central storage for storing data that comes from one or more heterogenous sources. It also consists of data which can be old and of historical value. One of the most important applications of this type of system is that it is used for supporting business intelligence and data analytics applications.

The stored procedure takes in 2 parameters, percentDiscount (DECIMAL(8,2)) and subject (VARCHAR(120)). Using these parameters, the stored procedure computes the discount for the book cost and stores it in the FINAL_PRICE field. For example, the following stored procedure call: call sp_apply_discount(0.15, 'Database');would compute 15% percent discount from the book cost in the Database subject category and store it in the FINAL_PRICE column as depicted in this image:
