ABSTRACT:
When a data manipulation language execution unit (120) executes a data manipulation routine, an object manipulation unit (150) requests a database access unit (170) to make the database access unit retrieve an object in order to obtain the object from a database (180). The object manipulation unit registers the object in an object descriptor table (160) and supplies the object to the data manipulation language execution unit. The data manipulation language execution unit accesses the object in accordance with an object descriptor and an attribute name. The object manipulation unit fetches the object designated with the descriptor from the object descriptor table. The object manipulation unit supplies object to an attribute extraction unit (140). The attribute extraction unit fetches an attribute in accordance with the object. A data conversion unit (130) converts the attribute into a conversion attribute having a format of a data manipulation language and supplies the conversion attribute to the data manipulation language execution unit.
