Your ERD should handle the following rules as a minimum but please use your
imagination to provide further rules:
a) A player must have at least one character and can create a new character or
deactivate one they no longer wish to play at any time. Once a player
unsubscribed from the game, the character is also removed from the system.
b) A player will be billed at the end of a calendar month for all active characters
for any part of that month.
c) A character can possess any number of inventory items (see Inventories.csv):
a. Weapons: have a range, damage points.
b. Armours: has a defence score and is worn on a speci c body part.
c. Supplies: have a healing score, mana score and if consumed increase the character’s life score by that amount (after which time the character will possess one fewer of that type of item)
d) Characters have combat info (see Combat.csv)
1. Your initial E-R diagram (WEEK 8 – 30%)
You will provide two outputs:
1) An English paragraph given in a PDF Þle that describes your personal ERD and
2) your ERD (embedded in the PDF Þle). We will assess your ERD by reading your paragraph.
You will receive full mark if your paragraph matches to your ERD.
Otherwise we will reduce your marks based on the following rules:
a) For each participation constraint fault (-1.5%).
b) For each multiplicity fault (-1.5%).
c) For each notation/Symbol fault (-1.5%).

In the followings we will provide you some requirements,
however we will expect you to exceed these expectations. You will need to demonstrate these in three milestones:
MILESTONES
1) Design and develop an Entity-Relationship Diagram (ERD) that models the following
key entities:
a) Customers/Players.
b) Characters.
c) Inventory for the various weapons and armour a character may possess.
d) Combat activities (#of kills, KIA’s, victories, etc.).

2) Write relational schema and integrity constraints for your relations. Provide the relevant SQL DDL statements to implement your ERD.
a) Pay careful attention to your choice of datatypes and consistency.
b) Consider referential integrity and nullable/not nullable attributes.
c) Make comment on the Normalisation level of your schemas.
d) Providing relational algebra statements is a bonus.
Assessment:
2. SQL DDL (30%)
You will provide a PDF Þle that contains your
Relational Schemas (RS),
Integrity Constraints (IC),
i.e.:
```
Mec_Repair(MID:integer, Name:string, Brand:string),
ICs: MID (Primary key), Brand (Foreign key referencing Car)
Normalisation reports: i.e. 3NF
DDL statements:
Car(Brand:string, weight:integer),
ICs: Brand (Primary key)
Normalisation reports: i.e. 3NF
DDL statements:
```
Normalisation reports for each RSs and
the DDL statements written in SQL.
You will receive full mark if your RS and ICs matches with your ERD. Otherwise, you we will reduce your mark based on the followings:
a) Typo for SQL code -2pts.
b) Reporting wrong Normalisation level -5pts.
c) IC mismatch from ERD to ICs or from ICs to DDL -10 pts.
d) Providing Relational Algebra statements (Bonus 10 pts)

3. Java Library and SQL queries (40%)
You will provide a java library that reads CSV Þle and builds required tables and answers the queries given above. You will receive full mark if your library successfully accomplishes these tasks. Otherwise we will reduce your mark according to the following rules:
a) Not compiles -100pts.
b) Compiles but cannot populate tables -50pts.
c) Cannot read CSV Þles but reads from other Þle format and populates tables - 0pts.
d) SQL Integrity Constraint warning, error while populating -10pts.
e) Failed to retrieve the answer for a query -10pts.
