Peer Review

INFS1200/INFS7900 Semester 2, 2003
Assignment 1 Part 2

Peer/Self Review Report

Group No. ___ 8 _______

Student No. 40529927 ________ Student Name: _ Ned Martin _______________

Peer Assessment for : _ SELF ___________ ___________________________

(Give Student No & Name of the peer; Write SELF for self assessment report):

Note: You are to fill out 3 peer assessment reports, 1 for each of your group members, and 1 self assessment report, for the design you submitted in part 1 of this assignment

1. Does the ER diagram conform to the notation/grammar of the ER model (Y/N) _ Y

If not, identify and explain the error

Correct notation and grammar appears to have been used throughout, however the diagram doesn't strictly read top down and left to right, with some relations being named in such a way as to cause right to left and bottom up reading.

 

 

Give 3 Marks for no error. Give 0, 1 or 2 marks otherwise, depending on the error 2 _

2. Are all the concepts given in the original universe of discourse covered in the ER diagram (Y/N) Y _

If not, identify what is missing

Entities

 

Relationships

- The relationship between route, stops and city has become somewhat polluted and could lead to duplication of stops, and definitely duplication of their city attributes.

Attributes

 

Constraints

 

Give 3 Marks if there is no missing concept. Give 0, 1 or 2 marks otherwise, depending on the omission _ 1

3. Is there any part of the ER diagram, which is incorrectly representing the universe of discourse (Y/N) _ N

If yes, identify and explain the error

Given the assumptions provided, I will say no, however, in hindsight some of those assumptions may not have been the best assumption in the situation, but I believe they are still technically correct.

 

Give 4 Marks for no error. Give 0 - 3 marks otherwise, depending on the error _ 3

Он стал лучшим программистом корпуса, и перед ним замаячила перспектива отличной военной карьеры. Но за два дня до окончания третьего боевого дежурства в его будущем произошел резкий зигзаг. В пьяной драке Хейл случайно убил сослуживца.

Корейское искусство самозащиты, тхеквондо, оказалось в большей мере смертоносным, нежели оборонительным. Военной службе пришел конец.
