+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)
