Abstract
An object encoding and computation method in a database system, where a global object sample space is constituted based on correlation between a plurality of object sample spaces in a database. A global dictionary table is created in the global object sample space to provide a globally unique encoding value for each object, set the encoding value as an object identifier (ID) of the object, and ensure that the object ID and object description information are in a one-to-one mapping relationship. The database object is encoded and compressed based on the global dictionary table. Further, the object ID is directly used for database query computation.
