CMIS 320 Lab 2 Homework 2 Data modeling and Sample database


Homework Submission Requirements:
Homework should be submitted as an attached file in your assignment folder. text for coding and result of execution and MS Word format for documenting are preferred. Data modeling diagram could be copied and pasted into a Word doc.
You must name your file to include your first initial of your first name and last name.
Part I is 4 points and Part II is 1 points. Total is 5. Quiz is not required for grading.


Part I Data Modeling
For each of the following descriptions:
a. A piano manufacturer wants to track all pianos it makes. Each piano has a unique serial number and a manufacturing completion date. Each instrument represents exactly one piano model, all of which have an identification number and model. The company produces thousands of pianos of a certain model, and the design is specified before any single piano exists.
b. A vendor builds multiple types of tablet computers. Each has a type identification number and a name. The key specifications for each type include amount of storage and display type. The company uses multiple processor types, exactly one of which is used for a specific tablet type. The same processor can be used in multiple types of tablets. Each processor has a manufacturer and a manufacturer's unique code that identifies it.
perform the following tasks:
1. Identify the degree and cardinalities of the relationship.
2. Express the relationships graphically with an E-R diagram.
Document your work into a single, well-organized, well-written word document and submit no later than due date.


Part II Lab 2
In lab 2, you will learn how to run a SQL script to create a sample database in your schema in NOVA Oracle database. You also start to learn simple SQL commands, such as select and insert


Click here to open Lab 2 instruction page


This part of lab is to learn to run a SQL script on NOVA Oracle database server, and spool screen output to a text file. These techniques will be used when you work on your project 1 and 2. Download script file. This is sql script file containing completed sql commands to create tables and constraints and populate data to each table. The database you create is called JustLee Book Store. The code should be bug free.
Download lab2.sql script
Start spool command and run the script:
Log on NOVA, make a dir named scripts using command mkdir scripts
Then cd to newly created script directory
Upload your script to scripts directory using FTP
(I downloaded a free FTP client CORE FTP LE) and use it to upload and download file)
Now you have a newly create dir and your script is uploaded. You are ready to run your script.
Using SQL*Plus, log on NOVA Oracle database with your account
At SQL prompt,Type the following command to turn on spool function: SQL>spool spool01.lst
spool01.lst is the spool file name
Then use this command to run the script: SQL>@lab2.sql
The command will execute all the SQL commands inside the script and output will be spooled to spool01.lst
In the script, there are drop table statement as well. When first run, these commands will fail because the tables are not created yet.
You can run the script multiple times without any problems.
When you finish the execution, issue command SQL>spool off
This command will end spool function and save output to the file you defined
When you have done all of these. Use FTP get spool01.lst to your local computer and submit it as part of homework 2
You should know how to perform the following tasks using sqlplus on NOVA Oracle database after you complete this lab:
Using FTP to upload or download a file (scripts...)
Using sqlplus to log on to NOVA Oracle database
Using sqlplus command, spool to output screen output to a text file and transfer the file back to your local PC.
Understand the steps taken place when you perform FTP file transfer and Spooling your output.
Test the database you create and learn SQL queries.
You need to spool the execution results of the following commands.
Do a database query: select table_name from user_tables; USER_TABLES is a database system view that allow users to see the tables they created in their own schema.
You should be able to list the tables you just created
use this query: select * from "table_name from the above query"; you can retrieve the data in these tables one a time
use this query: select count(*) from "table_name from the above query"; you can retrieve the record counts in these tables one a time
Use SQL*Plus command "desc books" to check columns and their datatypes. And insert one record into the table. Use SQL command "commit" to save the record into your database.
When you have done all of these. Use FTP get spooled file to your local computer and submit it as part of homework 2
