The objective of this thesis is to design and develop the object-oriented application framework for relational database application development. This framework is aspect for reusing in application level. With framework, application development will be easier. The novice programmers of designers can use the framework for developing relational database application by inserting, updating, deleting or selection the objects under the class relationship, which are single class, inheritance class, aggregation class and composition class. Programmers do not have to code SQL statement within application program since SQL statement will be hidden within the framework. The developed framework that is implemented with C++ language and MySQL the relational database will reduce the time used for designing and programming of the Sale Order applications development. Thus, these inexperienced programmers need not to be specialized in database design and management. Furthermore, By using this framework, the maintenance process will be more convenient than not using the framework and the code will be used without SQL statement. However, the analyst and programmer need more time to learn the framework at the beginning of the usage. Once they are familiar with the framework, they can construct application faster.
