Object-relational database management system (ORDBMS) using frame model approach

This paper describes a methodology and development approach to implement an object relational database management system (ORDBMS) with the frame model (Fong, 1997). The frame model method is a solution to extend relational database management systems (RDBMS) to handle complex data such as objects. Objects can be represented in a frame model schema as classes, constraints and methods. Schema translation is the first step to implement the object-relational database management system (ORDBMS). This paper investigates a stepwise methodology for schema translation from a relational model to a frame model. The second step is the implementation of ORDBMS to incorporate RDBMS as a kernel, application program interface (API) as interactive SQL and a method command interpreter. Methods are pre-compiled and stored in RDBMS as stored procedures. Methods can be invoked directly through API or a constraint class that is defined in the frame model schema when the associated interactive SQL is issued from the API.
