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.

Each publisher has a unique name; a mailing address and telephone number are also kept on eachpublisher. A publisher publishes one or more books; a book is published by exactly one publisher. Abook is identified by its ISBN, and other attributes are title, price, and number of pages. Each book iswritten by one or more authors; an author writes one or more books, potentially for differentpublishers. Each author is uniquely described by an author ID, and we know each author's name andaddress. Each author is paid a certain royalty rate on each book he or she authors, which potentiallyvaries for each book and for each author. An author receives a separate royalty check for each book heor she writes. Each check is identified by its check number, and we also keep track of the date andamount of each check.TasksDesign a SQL database using the above US superstore sales data set.1.Use Visual Paradigm to draw conceptual diagram2.Use Visual Paradigm todraw ERD

Given the business rule "An employee may have many degrees." Suppose that an employee has the following degrees. BA, BS, MBA, etc. These degrees could be stored in a single string as a multivalued attribute name EMP_DEGREE in an EMPLOYEE table such as the one shown below: EMP_NUM EMP_LNAME EMP_DEGREE 123 Carter BA, BS, MBA 124 Smith BBA, MBA 125 Jones AS 126 Doe BS, MS, PhD. This design is flawed, so correct it by creating additional table(s) and attributes(s) and show the relationships between them. Show all the data above in your table(s). Add additional data if new attributes were added. Show primary and foreign keys in your table(s).
