摘要
The present invention relates to a method indexing method and a dynamic change propagation method in a memory resident object-oriented DBMS.;The method indexing scheme proposed in the present invention uses a T-tree structure suitable for a memory-resident database as an index for finding the OID (s) of the object by using the method execution result value as a key. In addition, in the change propagation method executed when a database is changed, the method dependency information provided in the method definition is used to quickly reflect the effect of the database change in the method index.
