Tasks:

1) Using the student and faculty tables create a select query that outputs all students for a specific advisor. Generate the execution plan by first setting Autotrace on. Create an index that allows for a better join between the two tables. Again generate and display the revised execution plan using Autotrace.

The commands for using Autotrace are as follows:

SET AUTOTRACE ON;

SET AUTOTRACE OFF;

Format: Submit the code to create the tables, insert data, run the select, show the execution plan, create an index and then generate and show the execution plan again. You must submit the code as scripts that the instructor can run from an SQL prompt on an Oracle DBMS. Your submission must include a description of the scripts, their actions, and the order in which they should be run. Your code must not have any "side effects" (that is, it must not do anything not listed in the assignment description, and all of its actions must be described in the program header).

Goals:
Develop and demonstrate SQL skills
Develop your understanding of some database administration issues

Criteria:
1) Well-written code
2) Code meets requirements

These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.
