Yang Yu-fe · Journal of Jilin University · 2013
To solve the management problem of objects in object-oriented database,we describe an objectoriented database management system(OODBMS: Object Oriented Data Base Management System),the basic concept and its implementation process.The data model of the system,the system structure and implementation of the system modules are described in detail.The system introduces object-oriented concepts and methods to the traditional relational database storage structure for the underlying proposed object-oriented database data model to support the data type class layer relationships and inheritance,complex object management,version management capabilities,while detailed data definition(DDL: Data Definition Language) data manipulation(DML: Data Manipulation Language),the object module buffer management and query processing and version management and other subsystems of the implementation process and methods,and proposed that the system engineering database management aspects of a graphic image application,non-formatted data can be effectively managed.
