Use Figure 5.5 as a guide.Create a relational database design for the following data model For the imagemap this EER into a relational schema
- I need help with the following Consider a STUDENT relation in a UNIVERSITY database with the followingattributes (Name, Ssn, Local_phone, Address, Cell_phone, Age, Gpa). Note thatthe cell phone may be from a different city and state (or province) from thelocal phone. A possible tuple of the relation is shown below:Name Ssn Local_phone Address Cell_phone Age GpaGeorge Shaw 123-45-6789 555-1234 123 Main St., 555-4321 19 3.75William Edwards Anytown, CA 94539a. Identify the critical missing information from the Local_phone andCell_phone attributes. (Hint: How do you call someone who lives in a dif ferent state or province?)b. Would you store this additional information in the Local_phone andCell_phone attributes or add new attributes to the schema for STUDENT?c. Consider the Name attribute.

With respect to this relative schema, write SQL statements for the subsequent queries: List the name of the client United Nations agency has placed Order 123 (i.e. Order: = 123). List the names of shoppers United Nations agency in Cardiff and have ordered half 456 (i.e. Part. 456). List the order numbers (Order) for orders that contain a minimum of three elements and also the quantity ordered are minimum of ten.

- DATABASE SYSTEM A relation R is given which is R(A,B,C,D,E). It has the following functional dependencies: BC -> ADE , D -> B. Answer the following based on this information. Which normal forms does this relation satisfy? Which type of dependencies does this relation violate? Normalize the relationship so that it decomposes to 3NF.We have the following functional dependency A -> B. The following is a well-formed database design. MYTABLE (TheKey, A, B, C) True FalseThis is a database systems question I am unsure about the answer of: The price of a property fluctuates with time, and therefore depends on it. What is the additional functional dependency that reflects this fact? a. (DateSold, PriceSold) → PropertylD b. DateSold → PriceSold c. None of the other options d. (PropertylD, DateSold) → PriceSold e. PriceSold → DateSold
