Design and implement a relational database application of your choice using MS Workbench on

MySQL

a) Declare two relations (tables) using the SQL DDL. To each relation name, add the last 4 digits

of your Student-ID. Each relation (table) should have at least 4 attributes. Insert data to both

relations (tables); (15%)

b) Based on your expected use of the database, choose some of the attributes of each relation as

your primary keys (indexes). To each Primary Key name, add the last 4 digits of your Student-

ID by using Alter command. Explain why you choose them as the primary keys; (10%)

c) Specify one Update, one Delete, one Select, one Join, and one View in SQL that are needed by

your database application

Empirical evidence suggests that the Linder Effect is stronger in manufactured versus non-manufactured goods. This may be explained by the fact that non-manufactured goods are less differentiated and more standardised than manufactured goods.

Clearly indicate if the statement is true or false and briefly explain your answer

The component of spending that is responsible for most of the GDP decline during recessions tends to be

Social security payments fall under which category or categories of government expenditures (CHECK ALL ANSWERS THAT ARE CORRECT!)

Between 2000 and 2018, what happened to the U.S. trade balance in services?

True or False:

1. Logical database design is the process of modifying the physical database design to improve performance.
2. The two major logical database design techniques are conversion of E-R diagrams to relational tables and data normalization.
3. Multivalued attributes are not permitted in unnormalized data.
4. A many-to-many binary relationship in an E-R diagram requires the creation of a total of three tables in a relational database.
5. A one-to-one unary relationship in an E-R diagram requires the creation of a total of three tables in a relational database.
6. The input to the data normalization process is a list of the attributes in the database and a list of the functional dependencies among them.
7. The data normalization process is known as a “composition process.”
8. A group of tables is said to be in a particular normal form if every table in the group is in that normal form.
9. In first normal form tables every attribute value is atomic, that is no attribute is multi-valued.
10. Converting from first to second normal form involves subdividing tables to remove transitive dependencies.
11. A transitive dependency occurs when a non-key attribute determines another non-key attribute.
12. The data normalization process is progressive. If a group of tables is in second normal form it is also in third normal form.

Your database contains a role called nurse and many users who have that role. One of the users in the system is jackie. You need to write statements to implement the following privileges: All nurses should have read access to the shifts table; Jackie happens to be a nurse, but also has administrative duties and should be able to update, insert, and delete from the shifts table.

Write SQL that accomplishes this

Question on Database Systems - Concurrency Control

A popular update operation is increment/decrement the numeric value of data object by 1. Suppose we are now to create a lock mode I, along with usual shared and exclusive lock modes. Consider a locking protocol that will require a request for a lock with mode I on a data object Q (with numeric value) before proceeding with the increment/decrement operation on Q.
(i) Provide a lock compatibility matrix with these three modes.
(ii) Will this protocol provide more concurrency (data sharing) than the one with only shared and exclusive lock modes?
(iii) Suppose the increment/decrement operation is modified such that the operation will fail if the value of data object will become negative after the operation. Are your answers to (i) and (ii) still valid? Explain your answer.

*Industrial economics*

Select a firm or industry (AMAZON) and use the theory of non-price competition to carry out an analysis of the strategic behaviour of that firm or industry. As part of the answer, consider the strengths and weaknesses of the theory used. ALSO, Analyse how firms in the industry(AMAZON) engage in non-price competition. *WORD COUNT - 650* *Include reference and citations*

In response to question 4.2 from the textbook, demonstrate your understanding of the differences in the design, applications, and usage of the relational database as compared to the use of spreadsheets.

Question 4.2 Most DBMS packages contain data definition, data manipulation, and data query languages. For each of the following, indicate which language would be used and why. A database administrator defines the logical structure of the database. The controller requests a cost accounting report containing a list of all employees being paid for more than 10 hours of overtime in a given week. A programmer develops a program to update the fixed-assets records stored in the database. The human resources manager requests a report noting all employees who are retiring within five years. The inventory serial number field is extended in the inventory records to allow for recognition of additional inventory items with serial numbers containing more than 10 digits. A user develops a program to print out all purchases made during the past two weeks. An additional field is added to the fixed-asset records to record the estimated salvage value of each asset.
