A Background

1 Design and develop a database system for a sport tournament season

2 The database must consist of at least six tables populated with data

3 The database is to support queries that would typically be submitted to the system for the topical chosen area

4 Using Chen’s Notation for Entity Relationship Diagram (ERD)

5 Map the EER model into a relational data model normalized at least 3rd normal Form

6 Using appropriate SQL commands create a set of database tables in MS SQL Server 2008+ You should also show all constraints used in the creation of the tables
