Task 1 Database Design
Entity Relationship Diagram
Class Diagram is a part of Unified Modelling language whereas the Entity Relationship
diagram is a structural approach of system modelling. An ERD illustrates the real life objects as
entity, attributes and relationship between them. In the field of business information, software
engineering and education, the entity relationship diagram plays major role in development.
Below diagram has been mapped from the provided class diagram of the Thomson Cycle where
the methods are not included as an ERD only contains attributes. The stock maintenance and
system interface class has not been taken into the account as they contain product related
attributes. They have been included in the product table. Also the order status class is also
eliminated due to not having atomic values and it is related to the order table, hence an attribute
named “Status” has been included in the order table. The table booking reference has also been
neglected as it does contributes heavily in the process of booking and order system.
