Welcome Back ! Hope you enjoyed the Happy Holi and long semester break –Good, now get back to work…

ASSIGNMENT 14 WEEK 9 LAB A and B [28/03/2011 TO 02/04/2011]/Marks 90 EVALUATION DATE WEEK 10 [04/04/2011-09/04/2011] LAB A Q1 AND LAB B Q2 AND 3

NOTE <Codes, UML and ER Diagram should be neatly written and drawn on Paper with name and enrollment no at top, Project Title and strictly no Software/Editor usage--and to be done individually in lab not group-wise>. This has to be shown to lab teacher only at evaluation date.

Question 1. Analyze the current project. Now Make a Draft of your Project on similar 6 points writing code and Diagrams wherever necessary using OOSP Concepts, this work will be incremented by ongoing lectures and labs[Normalization and Connectivity Topics to be attended with Ongoing Lectures done in class i.e. will be covered in lecture this week but has to be completed by evaluation date]. The topics here to be referred are given. But these 6 Points should be clearly mapped with your Project Domain. Draft -1 will consist of Q1, 2 and Q3part B> You can refer DBMS Validation and Verification Questions given in T2 Question Paper or old DBMS Labs. TDD APPROACH: Write your Verification and Validation Codes on those formats using Joins, Nested Queries, Advances Select, User and System Defined EXCEPTIONS.

Example Case Study: The Cafeteria Information system:1. Single application: single class, single function. Class: CafeteriaFunction: Food_ZoneAttributes: Cafeteria::Food_Zone: Menu_card,Bill

2. Single application: single class, multiple functions. Class: CafeteriaFunction: Food_Zone, Customer_Record, Staff_RecordAttributes: Cafeteria:: Food_Zone: Menu_card, BillCafeteria:: Customer_Record: customer_name,customer_bdayCafeteria:: Staff_Record: staff_id, staff_name, staff_record

3. Single application: multiple classes, multiple functions, simple relation. Class: Cafeteria, Customer Function: Cafeteria: Parking, Staff_Record, MenuCustomer: Customer_RecordAttributes: Cafeteria:: Parking:p_typeCafeteria:: Menu:bill Cafeteria:: staff_record: staff_id, staff_name,staff_job Customer:: Customer_Record: cutomer_name, cutomer_bdate

OOSP Concepts: TDD Approach: Validation of variables in methods, Casting for formats ex: bdate format, name is string, staff id in integer, parking can be filled in 2 types, non vegItems present in menu or not etc.

4. Single application with persistent data: multiple classes, multiple functions, simple class relation, multiple data table.

Class: Cafeteria, Customer Function: Cafeteria: Parking, Staff_Record, MenuCustomer: Customer_RecordAttributes: Cafeteria:: Parking:p_typeCafeteria:: Menu:bill Cafeteria:: staff_record: staff_id, staff_name,staff_job Customer:: Customer_Record: cutomer_name, cutomer_bdate

OOSP Concepts: OO Concepts: Objects, Classes, Inner classes, Methods, Constructors, Static member functions , Wrapper Classes, Packages and Interfaces and Garbage collection + Introduction to RDBMS, create table, simple create,insert, select.= [1,2,3,4]DBMS Tables for the same,Create Data, INSERT Data AND select //simple sqlTDD Approach=Simple Select + Simple Exception Handling

5. Single application with persistent data: multiple classes, multiple functions, complex class relation (inheritance), multiple data table. Class: Cafeteria, Customer Function: Cafeteria: Parking, Staff_Record, MenuCustomer: Customer_RecordAttributes: Cafeteria:: Parking:p_typeCafeteria:: Menu:bill Cafeteria:: staff_record: staff_id, staff_name,staff_job Customer:: Customer_Record: cutomer_name, cutomer_bdate

OOSP Concepts: Inheritance+ Software Development Life Cycle Models DBMS Tables for the same, ADVANCED SQL::Create Data, INSERT Data AND select For TDD Approach //Advanced sql-NESTED –part 1+NormalizationTDD Approach=Adv. Select + User Defined /System Defined Exception Handling

6. Single application with persistent data: multiple classes, multiple functions, complex class relation (polymorphism), multiple data table.

OOSP Concepts: Polymorphism+ System Analysis and Design Methodologies, UML (Object diagram, Class diagram-(Part of Q2 so attend in Q2 Only)+Connecting with simple access table+DBMS Tables for the same i.e. INSERT Data, Create Data //Advanced sql-JOINS-part 2 +ER i.e. Entity Relationship Diagram (Part of Q3 so attend in Q3 Only)+TDD Approach=Adv. Select + User Defined /System Defined Exception Handling

Question 2. Most of your project UML’S have errors so rectify and make a Draft of all UML’S for your Project Use Cases as Lab Assignment

1. Use Case2. Activity3. Sequence 4. Class and Object Diagram5. Collaboration 6. Component. ( To be submitted with the final report)7. Deployment.( To be submitted with the final report)

Q3 A>Consider the following information about a university database: Professors have an SSN, a name, an age, a rank, and a research specialty. Projects have a project number, a sponsor name (e.g., NSF), a starting date, an

ending date, and a budget. Graduate students have an SSN, a name, an age, and a degree program (e.g., M.S.

or Ph.D.). Each project is managed by one professor (known as the project’s principal

investigator). Each project is worked on by one or more professors (known as the project’s

co-investigators). Professors can manage and/or work on multiple projects. Each project is worked on by one or more graduate students (known as the

project’s research assistants). When graduate students work on a project, a professor must supervise their work

on the project. Graduate students can work on multiple projects, in which casethey will have a (potentially different) supervisor for each one.

Departments have a department number, a department name, and a main office. Departments have a professor (known as the chairman) who runs the department. Professors work in one or more departments, and for each department that they

work in, a time percentage is associated with their job. Graduate students have one major department in which they are working on their

degree. Each graduate student has another, more senior graduate student (known as a

student advisor) who advises him or her on what courses to take.

Design and draw an ER diagram that captures the information about the university.Use only the basic ER model here; that is, entities, relationships, and attributes. Besure to indicate any key and participation constraints.

Question 3 B>Now make Advance ER-Diagram for your project.
