SQL.   I have 35 written questions and 5 SQL assignments.I will provide all three Query languages for the database and the ER Diagram.  For the SQL assignments, you must provide both the SQL statement and the output of your work. So for example1. SQL statement here —-Output here — 2. SQL statement here — You can use word or notepad to provide the answers just have it be somewhat clean looking. If there are any questions feel free to PM me we can negotiate on price as well. I NEED this done.

When does a database have integrity? 8. What is data independence? Why is it desirable? 9. How can the complexity of a DBMS be a disadvantage? 10. Why can a failure in a database environment be more serious than an error in a non-database environment? Review Questions 2 Please answer these questions in your own words: 1. What is a relational database? 2. What is an unnormalized relation? Is it a relation according to the definition of the word relation? 3. How is the term attribute used in the relational model? What is a more common name for attribute? 4. What is a primary key? What is the primary key for each table in the Colonial Adventure Tours database shown in the Colonial Tours ER Diagram file? 5. Describe the purpose of the UNION command in relational algebra. Review Questions 3 Please answer these questions in your own words: 1. Define functional dependence. 2. Define candidate key. 3. Define first normal form. 4. Define second normal form. What types of problems would you find in tables that are not in second normal form? 5. Define third normal form. What types of problems would you find in tables that are not in third normal form? Review Questions 4 Please answer these questions in your own words: 1. Define the term user view as it applies to database design. 2. The information-level design method presented in this lecture contains steps that must be repeated for each user view. List the steps and briefly describe the kinds of activities that must take place at each step. 3. A database at a college is required to support the following requirements. Complete the information- level design for this set of requirements. Use your own experience to determine any constraints you need that are not stated in the problem. Represent the answer in DBDL. – For a department, store its number and name. – For an advisor, store his or her number and name and the number of the department to which he or she is assigned. – For a course, store its code and description (for example, MTH110 or Algebra). – For a student, store his or her number and name. For each course the student has taken, store the course code, course description, and grade received. In addition, store the number and name of the student’s advisor. Assume that an advisor may advise any number of students but that each student has just one advisor. 4. List the changes you would need to make in your answer to Question 3 if a student could have more than one advisor. 5. Suppose in addition to the requirements specified in Question 4, you must store the number of the department in which the student is majoring. Indicate the changes this would cause in the design if the student’s advisor does not necessarily have to be in the department in which the student is majoring. Review Questions 5 Please answer these questions in your own words: 1. What is metadata? Which component of a DBMS maintains meta data? 2. How does a catalog differ from a data dictionary? 3.

CIS240 – Assignment 1 Student Key Creating Tables For each question below, write and execute the appropriate SQL statement in the Database Management System of your choice using the indicated database. Please provide both the SQL statement and the output from your statement. You may copy and paste or provide screen shots of your work. If you provide your work in a separate document, please be certain to number your responses. Submit your completed assignment to the appropriate Assignment Submission Folder in the course shell by the due date indicated on the Course Schedule. 8 points Use the BITS database for steps 1-4. 1. Create a table named Location. The Location table should have the same structure as the Trip table from the Colonial Adventure Tours database (see the ER Diagram), but with the following changes (2pts): a. Change TripID to LocationID and use the number/numeric data type (use number for Oracle and numeric for all other DBMSs). b. Change TripName to LocationName. c. Change the data type for the Distance column to decimal(4,1). * Table should be created successfully. 2. Insert the following records into the Location table (1pt): 42,Poudre River Trail,Island Grove Park,CO,21.4,10,Biking,Late Spring 43,Pikes Peak,Barr Trail,CO,26,12,Hiking,Early Fall * Insertion should succeed. 3. Display the contents of the Location table to ensure the records were added correctly. (1pt) 4. Remove the Location table. Ensure that it was dropped successfully using a query or describe statement. (1pt) * Query should fail. 5. Run the appropriate script file to create the Colonial Adventure Tours database. Make sure that you run the correct file for the Database Management System you are using. (1pt) * Commands should complete successfully. 6. Double check that you are switched to the Colonial database (in Oracle SQL Developer, this will require creating a connection for the Colonial user). Verify that the database was created correctly by using a DESCRIBE (or equivalent) command for each table and comparing it to the ER diagram. (1pt) 7. Verify that the data was loaded correctly by querying each table and comparing the results to pages 16-20 in the Concepts book.
