How many fields are there per record? There are total of six records and five fields per records. 2. What problem would you encounter if you wanted to produce a listing by city? How would you solve this problem by altering the file structure? Since the data is multivalued in the form of address it is hard to separate city from the whole address. To solve this problem the data should be single valued which means each field should have only one data. So, we need to make one separate file to store just the city name. 3. If you wanted to produce a listing of the file contents by last name, area code, city, state, or zip code, how would you alter the file structure? The name should be separated as first name and last name and the address field should be separated as area code, city and state. 4. What data redundancies do you detect? How could those redundancies lead to anomalies?

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.
