Data Management
Develop a persistence mechanism using data access objects for the domain objects involved in the CCRD use case.
Map the information required by the relevant domain object classes onto a set of relational database tables in third normal form. Specify the table design.
For all the associations that exist for the chosen domain object class, discuss how referential integrity can be maintained.
Design data access object (DAO) classes to support interaction between the object oriented case study application and a relational database.
Specify the attributes and operations for these data access object classes.
Ensure that the sequence diagram you developed for Part B shows all required interactions with and between the classes of the persistence layer. Also show interactions between the persistence layer and the database.
