***Grading Policy for EER***


3 marks each for showing class-subclass relations
(i)  Vehicle -> car, bicycle
(ii) Student-> masters, PhD
(iii)Task -> picture,video 

(if missing subtract 1marks for each)

2 marks each for showing disjoint and overlap correctly
(i)  Vehicle -> disjoint
(ii) Student -> overlap



10 marks for finding the 10 entities correctly
Approximately 1 mark for each entity
(Sometimes, relations will be put as entities...so they might have more
entities....if you think some entities are missing, subtract 1 mark for
each)

6 marks for finding the relations correctly
Approximately 1 mark for each relation. 
Make sure that one-to-many (station-building, task-path) and other many-to-many( student-vehicle) are in place.
Subtract 1 mark if they didnt catch any of these realtions right. 

4 Marks : See to it that most of the attributes needed are present in their
solution. Its OK if some of them are missing. Subtract some marks 
if MANY attributes are missing. Missing Attributes (max 4 marks)

5 marks : Address Attribute in the Student should be shown as composite
attribute 
Phone Attribute  should be multivalued
GeoCoordinate  should be composite 
TimeSchedule   should be composite
DrivingSchedule  should be composite

(Take 1 marks each if any missing, Max 5 marks)


1 Mark Age Attribute in Driver  should be derived (subtract 1 mark if missing)

6 Marks Take 1 point off if any primary key missing (max 6 marks)

1 Mark Total Participation from Station to Building and Task to student. Subtract 1mark if missing 

1 Mark SeqNo Attribute in Consists relation between path and Station Entity (subtract 1 mark if missing)

1 Mark Take 1 marks off if the student didnt catch task - station (start and end) n-ary realtion



Note : 1. Task type is also correct if shown as an attribute in place of Class-subclass relation

	   2. Car type is also correct if shown as a Class-subclass relation in place of attribute 
	   
	   3. A direct relation from Student to Task is also correct.
