Provided is a method, system, program, and data structures for maintaining
a database of objects. At least one structured document is received representing
an instance of an object including attributes and attribute values defined for
a class. Content of the structured document representing the object is added into
a database, wherein the database is capable of storing multiple structured documents
representing multiple objects. In another implementation, an instance of at least
one object including attributes and attribute values defined for a class is generated.
For each generated object, a structured document is generated representing the
object and including a representation of the attributes and attribute values in
the object. Each structured document is transferred to a database program to maintain.
