- 1. ECET 450: Laboratory 2 Part B: Purpose: This laboratory provides practice in the creation of realistic tables and their relationships using Oracle SQL*Plus and introduces writing SQL*Plus script files. This laboratory exercise creates a relatively simple invoice system using SQL statements. This DB schema is used throughout the next several weeks of laboratory exercises. The final product is an SQL script that makes it possible to initially create and re-create, if need be, the DB schema in order to do to the later laboratory exercises. Procedure: Using your assigned user name, password, and host string, log in to Oracle SQL*Plus. Record your dialog with a spool file. Following the four requirements below, create the 5 tables shown later in this laboratory exercise, and enter all data as shown. Be sure to record your interactions with SQL*Plus using the spool command. 1. Use table names, attribute names, and data exactly as shown. The one exception is that you will omit the dollar sign and comma separators in the money amounts. Accurately enter the data as you will need these tables in future laboratory assignments. 2. Save all of your commands in a single script file for printing and submission. This file should each contain a minimum of
- 2. your name and the date in comments at the beginning of the file, and any other comments you feel add to the understanding of the script file. Copy and edit your spool file to create the load_tablesXXX.sql file where XXX are your initials. The only items that should be in this load_tablesXXX.sql file are your comments and the SQL statements that drop tables, create tables, insert data values, and display table. Be sure to remove all incorrect commands and the Oracle responses to the correct commands from the file. Save this file for the future in case you have to rebuild these tables. Be sure to include a printout of this file in your report. 3. The second submission requirement is a printout of each of the 5 tables completely loaded with the specified data. Use the SET LINESIZE command to avoid line wrap around of your table data. Print your list file in landscape mode. 4. All primary key and foreign key constraints should be named according to the method presented in the classroom. If you have any questions about which attributes are primary and/or foreign keys, please ask about them. 5. The ultimate test is the execution of this SQL script file in the following form: @ <path_name>/load_tablesXXX.sql <First Page of tables> REP Table REP_ID REP_LNAME REP_FNAME REP_STREET REP_CITY REP_STATE REP_ZIP REP_COMM

The steps to complete this exercise include getting the data items into 1NF, 2NF, and 3NF. The final step is to generate the ERD for the table or tables that are in the dependency diagram in 3NF. Discussion: Some small business wants to keep track of office furniture, computers, printers, etc. A sample of the ITEM records is shown below: ATTRIBUTE NAME SAMPLE VALUE SAMPLE VALUE SAMPLE VALUE ITEM_ID D1342245 D1453356 D1365779 ITEM_DESCRIPTION IQ Deskjet 683P IQ Toner DT Photocopier ROOM_NUMBER 227 227

In particular, the student executes and edits SQL commands in the command line interface to create and populate a small table. Procedure: 1. Following the specified directions, and using your assigned user name, password, and host string, log in to SQL*Plus.
- 23. 2. Change your password to something you will remember. Type the following at the SQL> prompt ALTER USER user_name IDENTIFIED BY new_password; 3. In order to do this laboratory exercise, it is necessary for you to save all your command-line inputs and Oracle’s responses. At the SQL> prompt the general form of the spool command is spool p:<path_name>/<list_file_name>. For example, the professor might use the following command spoolf:/ecet450/lab01a/lab01a.lst. Be sure to create all the folders in the path first. 4. Use the CREATE TABLE and INSERT INTO commands to create the EMPLOYEE table shown on the next page. Use the decimal data type for numeric attributes. Use the edit commands as needed to fix any errors along the way. 5. When you are done, use the SELECT statement to display your finished table. 6. At the SQL> prompt enter the spool off command to terminate collection of your dialog. Your dialog is not placed into your list file until you execute this command. If you exit from SQL*Plus before executing the spool off command, your dialog will be lost. 7. Type EXIT to terminate SQL*Plus. 8. Print your list file, be sure to write your name on it, and submit it at the time and in the manner specified by your instructor.

EMP_LNAME is a variable length character string no larger than 16 characters. EMP_DEP is a small decimal representing the number of dependents for tax purposes. EMP_HIRE_DATE is the employee’s hire date. EMP_PAY is the employee’s hourly rate that a 5, 2 format should accommodate. Part B: Purpose:
- 25. This laboratory exercise introduces the concept of the Entity Relationship Diagram (ERD). The work should be done using the MS Visio tool using a crow’s foot ERD. The finished ERD should not contain a many-to-many relationship. Note that this exercise is concerned with only a small part of a larger DB. Discussion: A college wants to add extracurricular activities to its DB containing student data. The student table contains the student's identifier, his/her name, his/her address, his/her primary telephone number, and his/her birth date. The new activity table contains data about the college's recognized extracurricular activities including the activity's name, the name of the activity’s advisor, and the advisor’s office location. The college wants to also track the number of years that a specific student participates in a specific extracurricular activity. Obviously more than one student must participate in an extracurricular activity in order for the college to recognize the activity. Also a specific student may participate in zero, one, or several extracurricular activities. As a result, the student table and the activity table have a many-to-many relationship. In addition a specific student may have participated in one activity, e.g. IEEE student chapter, for three years and in another activity, e.g. TAP honorary, starting this year. Using the MS Visio drawing tool, draw a crow’s foot ERD that describes the Student table, the Activity table, any other needed tables, and the relationships among these tables. Be sure to include the following items in your diagram: 1. Update all attribute names so that they partially or completely contain the name of the table in which they reside. 2. Identify the attribute or the group of attributes that is the primary key of each table. 3. Modify your ERD so that it does not include any many-to- many (M:N) relationships. 4. Indicate the connectivity of each relationship, i.e. 1:1, 1:M, and M:N, using the correct crow’s foot symbols.
