  8. CIS 336 expert tutorial CIS 336 Week 1 iLab 1 Devry University (Devry) CIS 336 Week 2 iLab 2 Devry University (Devry) • L A B O V E R V I E W Scenario/Summary This lab will introduce you to the processes involved in defining one of the key components of a data model; the relationship diagram (RD). In this lab, you will draw a relationship diagram for two of the steps shown. Keep in mind when you are trying to decide which side of the relationship should be the "one" side and which should be the "many" that you must first decide which side has the primary key, or unique identifier. • Lab two introduces the next step in creating a data model, the Entity Relationship Diagram (ERD). You will be given a business scenario for a company named Clapham Specialty Store, which is a small specialist grocery and delicatessen. The business specifications will outline a number of things about the business, some of which will apply directly to the database you are being asked to model. There is a table which lists the entities (tables) that will be needed for the database and related attributes (columns) for each entity.

  9. CIS 336 expert tutorial CIS 336 Week 3 Group Project Task 1 Data Model (Devry) CIS 336 Week 3 iLab 3 Devry University (Devry) • Present a detailed data model for the project scenario. You can create your data model using Microsoft Visio, which you will have access to through iLab and Microsoft Excel, which comes with Microsoft Office. Other tools may be used as long as the output is legible and conforms to standard format. (i.e. I will not be able to grade the data model if I cannot tell what it is supposed to be!). Your data model should include a minimum of an ERD and metadata chart (data dictionary). • Beginning with this lab, and continuing through the remaining weeks you will be doing all of your work in Oracle itself. The editor interface to the Oracle server is SQL*Plus, and by now you have received your logon ID and password and should have at least made sure you can connect. If for any reason you have not done so, please do so now before continuing any further. If for any reason you cannot connect then you need to let the instructor know ASAP so that any problems can be resolved.

  10. CIS 336 expert tutorial CIS 336 Week 4 Group Project Task 2 (Devry) CIS 336 Week 4 iLab 4 Devry University (Devry) • Task 2 - Logical Model (30 points) • Using the Oracle SQL*Plus editor, develop a database for MiniQuest based on your data model. The database should contain all the tables and attributes discussed in the project specifications. Be sure to use your data dictionary when creating your tables. • A key component to every task submission is the team responsibilities document. This document should outline the contributions that each member of the team made to completing the task deliverable. To submit this task, you need to create a file in notepad called TEAM_X_TASK2.TXT, where X is your team identifier. For example, Team A would name the file TEAM_A_TASK2.TXT. • Lab 4 of 7: Building the Physical Model (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 #4 will introduce the various aspects of the SQL select statement and the methods of retrieving data from the database tables.

  11. CIS 336 expert tutorial CIS 336 Week 5 Group Project Task 3 (Devry) CIS 336 Week 5 iLab 5 DevryUniversity (Devry) • 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.

  12. CIS 336 expert tutorial CIS 336 Week 6 Group Project Task 4 (Devry) CIS 336 Week 6 iLab 6 Devry University (Devry) • Task 4 - Verification of Transaction Processing (30 points) • Develop a query that will identify and mark inactive those customers that have bills overdue by more than 30 days (this can usually be done using a sub-query). Remember, you are only marking a customer as inactive, not actually deleting the customer record from the system. • Week 6. L A B S T E P S STEP 1: Back to top Using the BOOK_CUSTOMER table and the NVL function, create a query that will return a list containing the customer number, first name, last name, and the characters ‘NOT REFERRED’ if the customer was not referred by another customer. Give the derived column an alias of REFERRED BY. Do not list any customers that were referred by another customer. STEP 2: Back to top Using the BOOKS table and the SUBSTR function, create a query that will return a list of book ISBN codes and the book title for all the computer books.

  13. CIS 336 expert tutorial CIS 336 Week 7 Group Project Task 5 (Devry) CIS 336 Week 7 iLab 7 Devry University (Devry) • Develop the queries to support each of the reports that are required by Ms. Smith. It is expected that the information returned by the queries is adequate to be used in the reporting process. Make sure your output contains enough information! The following is a recommendation and the MINIMUM amount of data you should have access to: • L A B O V E R V I E W Scenario/Summary There is a lot more to a database than just tables and the data in them. A very important part of database security has to do with using and understanding Database Views. Being able to enhance the efficiency of the database tables by using additional indexes is also a very important aspect of database development. Finally, being able to create and use Database Sequences to automate some of the sequential processes in the database can not only save time but improve efficiency.
