Design and Implementation of a Compiler for the Object-Oriented Data ManipulationLanguage

摘要

Object-oriented relationships, such as inheritance and covering can not bereadily incorporated in classic data models. This thesis addresses this problem by the design and implementation of an object-oriented data model (O-ODM), that incorporates the object-oriented paradigm. A Multimodel and Multilingual Database System called M2DBS has been developed at the Naval Postgraduate School. This system incorporates the classic database data models along with a recently developed object-oriented data model (O-ODM). The problem addressed by this work is to design a new object-oriented data manipulation language (O-ODML) for the O-ODM. The approach is to develop and construct an O-ODML Compiler. Then assimilate the compiler with the Kernel Mapping System (KMS) of the M2DBS. The result of this thesis is a compiler for the O-ODML of the O-ODM. This O-ODML compiler takes an O-ODM query converts it into a low level intermediate language before translating it into a format that the Real Time Monitor can execute on the M2DBS. (AN).
