+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%).
+
+2. SQL DDL ( WEEK 9 – 30%)
+   You will provide a PDF Þle that contains your
+   Relational Schemas (RS),
+   Integrity Constraints (IC),
+   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) For each typo for SQL code (-0.6%).
+b) Reporting wrong(or none) Normalisation level (for each table -1.5%).
+c) For each IC mismatch (from ERD to ICs) and (from ICs to DDL) (-3%).
+
+3. Java Library and SQL queries (WEEK 10 – 40%)
+   You will provide a PDF Þle that contains the English versions of your queries.
+   You will also provide a java library that reads CSV Þle and
+   builds required tables and answers the queries you provided.
+   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 (-40%).
+   b) Compiles but cannot populate tables (-20%).
+   c) Cannot read CSV Þles but read from other Þle format and populates tables (-0%).
+   d) For each SQL warning, error (-3%).
+   e) For each failed query (-3%).
+   f) Providing Relational Algebra statements (for each query) (+3%)
