6.4 Case Study of Converting a Relational Database to

Object-Oriented

An existing RDBMS database application is used to demonstrate the ability of
OFMA. The application describes the relationship of staff, student, and course of
college departments. The RDBMS schema is re-engineered, and was redefined in
Object schema. New instances of Header Class were created for each table of the
RDBMS schema and class operation. A new instance was created for Method Class
for the method that was defined in Header Class, Attribute Class, or Constraint
Class. The case study demonstrates the possibility of employing frame model meta-
data to implement OODBC. Object behaviors such as encapsulation, inheritance,
polymorphism, abstract data type, constraint, and path expression for OODBC will
be shown using examples. In addition to the object behaviors, the relational behav-
