Subject RE: Avalon DB
Date Mon, 29 Oct 2001 18:14:26 GMT
Hello,
I did a little bit brainstorming.
what about objects/wrappers/interfaces/libaries for:
  (Transaction)
  Cursor
  Trigger
  Constraint(unique,referential)
  Key(primary,...)
  Datatypes(SMALLINT,INTEGER,...)
  User Management(SCHEMAS,...)
  Functions(MIN,MAX,AVG,SUM,...)
  more Actions: ALTER,GRANT,...

greets
Gerhard
