L A B S T E P S STEP 1: Drawing your first ER diagram Title Identify the foreign key

columns in the table structures above and draw a relationship diagram depicting the

relationships between the tables. In the Order table , the CustNo column references

the Customer table and the EmpNo column references the Employee table. For each

relationship, identify the table on the "1" side of the relationship and the table on the

"Many" side. STEP 2: Extending the ER diagram Extend your relationship diagram

from problem 1 by adding two tables (OrdLine and Product). Table definitions for

the table structures and primary keys constraints are shown below. You will need to

identify the FOREIGN KEY(s) to complete this problem.

http://www.cis336papers.com/CIS-336/product-29-CIS-336-Week-1-iLab-1-Devry-University





L A B S T E P S STEP 1: Drawing entities and attributes Be sure to include all of the

entities that have been defined. You need to include at least the primary and foreign

key attributes where applicable in your diagram. STEP 2: Indication of all

relationships Be sure that you link all entities based on PK to FK relationships.

There may be a case where you need to identify a combination PK and if so make

sure that all of the relationships involved are defined. Be sure that you have set your

Visio editor to show Crow's Foot notation. Also, be sure that you are defining the

correct cardinality for the relationships. STEP 3: Naming of relationships Do not

accept the default naming convention for your relationships in all cases.



CIS 336 Week 3 Group Project Task 1 Data Model (Devry)



Deliverables for this task:

A completed Data Model to include: An ERD, showing all tables, related attributes,

and the primary and foreign keys. This diagram must show both the relationship

and cardinality of the relationship using accepted notation. A Data Dictionary (or

meta data chart) showing a minimum of the table name, columns, data types, length,

and constraints. Team member responsibilities document outlining contributions by

team members to this deliverable.

STEP 4: The SELECT statements The next step of the lab will be to create the select

statements to verify the data was inserted correctly. You should have seven select

statements; one for each table. The command is SELECT * FROM Table_Name;

For example, to select all columns from the Student table, the command would be

SELECT * FROM Student; Be sure to save all of the above statements in your

script file. STEP 5: Testing and verifying your script Now we come to the point of

verifying that your script file works by creating all of the tables and inserting all of

the data.



CIS 336 Week 4 Group Project Task 2 (Devry)



DROP TABLE CUSTOMER CASCADE CONSTRAINTS PURGE;

After testing and verifying that all of your create statements work, create a spooled

output file with the SET ECHO ON session command set so that your code and the

results will show.


Revisions of Task 1 (if any) based on feedback from your instructor. Task 2 comprised

of the CREATE TABLE script file and the output file showing that it works. Team

member responsibilities document outlining contributions by team members to this

deliverable.

L A B S T E P S STEP 1: Using the BOOKS table, write a query that will list the

categories for the books in inventory. List each category only once in your result

set. STEP 2: Using the BOOKS table, write a query that will list the title and

publisher ID for each book in the table. Use the column heading of "Publisher ID"

for the pubid field. STEP 3: Using the BOOKS table, write a query that will list the

book title, retail price, and the amount of markup for each book. The amount of

markup is the retail price minus the cost. Use the column heading “Price Markup”

for the arithmetic expression column. STEP 4: Using the BOOK_CUSTOMER

table, write a query that will list the customer’s first name, last name, and city for

those customers living in zip code 31206.






Task 3 - Verification of Logical Model(45 points)

Develop the SQL statements to insert records into the database. You should ensure that

the data in the database is sufficient to allow for each of the reports requested by

Ms. Smith to be tested. You need to show a minimum of three insert queries for

each database table that you have created. Some tables will obviously require more

to ensure that all of the required data is in the database (i.e., the packages table,

program table, etc). To submit this task, add a comment heading called INSERT

STATEMENTS to your corrected SQL script from Task 2.






Lab 5 of 7: Retreiving data from Multiple Tables (28 points) Submit your assignment

to the Dropbox located on the silver tab at the top of this page. For instructions on

how to use the Dropbox, please click here. (See Syllabus/"Due Dates for

Assignments & Exams" for due dates.) L A B O V E R V I E W Scenario/Summary

Lab 5 deals with writing queries using multiple tables as covered in the reading and

lecture material this week. In some cases, you will be given the option to write a

query using either the TRADITIONAL method of joining tables or using the JOIN

key word. In some cases, you will be asked to use a specific approach.







Any revisions of task 3 based on feedback from your instructor. Task 4 comprised of

the complete script file (DROP, CREATE, INSERT, SELECT, and UPDATE

statements) and the output file showing that it works. Team member responsibilities

document outlining contributions by team member to this deliverable.






STEP 12: Back to top Using the BOOK_CUSTOMER table, write a sub query that

will return the names of those customers who were referred by the same individual

who referred Jorge Perez. Do not display Jorge Perez’s name in the returned results

(Hint: you should only have two customers displayed and the exclusion for Jorge

Perez must be associated with the upper query). STEP 13: Back to top Using the

BOOKS table, create a query using the correct functions to return the category

name, total number books per category with a column alias of "Category Total", and

the total cost of all the books per category with an alias of "Cost".






Create a heading of REPORTING STATEMENTS as a comment at the bottom of your

group project database script file. Add the six report queries to this area. In

instances where you are asked to allow for user input, please specify an appropriate

value based upon the data in your script. For example, Report 1 is a DATE driven

report; therefore, you should use a single date in your WHERE clause to display the

information. Task 5 is the final task for the project and is designed to demonstrate

that you have adequately satisfied the requirements of the project. The following is

what you are to submit for Task 5:






STEP 7: Create a unique index on the combined columns ORDERID and

CUSTOMERID in the BOOK_ORDER table. Give the index a name of

BOOK_ORDER_IDX. STEP 8: Determine how many objects you currently own in

your schema by querying the USER_OBJECTS view in the Data Dictionary. Your

result set should list the different object types that you find and include a count by

object type.
