SYSTEM AND METHOD FOR STORING AND OBTAINING FIELD OF USER DEFINED TYPE OUTSIDE OF DATABASE STORE IN WHICH TYPE IS DEFINED

PROBLEM TO BE SOLVED: To allow a user to define a type of an object which can be connected to a database store. SOLUTION: One or more fields of the type definition may be designated as containing data of a type that is to be stored as a file outside of the database store and separately from the other fields of the type definition. When a request is received to store an object that is an instance of the user defined type, the data in any field of the object designated to include the data of the type is stored in a file outside the database store, within a file system of the computer on which the database store is implemented. The data in each of the other fields of the object is stored within the database store in the usual manner. The database store maintains a link, or reference, between the persisted object and the data of the field that is stored as a file outside of the database. COPYRIGHT: (C)2011,JPO&INPIT
