Abstract: | This paper summarizes the design and implementation notes of the CodDdBase system, which is a combinative distributed database management system family based on an integrated object model. CoDdBase is implemented in CLUSTER 86, a general purposed object-oriented programming language designed by the authors. The CoDdBase environment is actually a part of the CLUSTER 86 programming environment, which offers various object-based models, supplies miscellaneous building blocks for constructing different distributed DBMS’s, and provides integrated programming tools to develop new ways and new models in response to changing application needs. |
