ABSTRACT:
A Composite Pattern with BLOB data types is used to model a hierarchical network, and includes a path-like construct for locating each component within the network model. Database procedures are used to efficiently search, modify and retrieve individual nodes from the network model using the database server's memory pool so that client applications are not required to retrieve and deserialize the entire Composite-BLOB hierarchy in order to make modifications or search for individual elements, thereby substantially reducing the transfer of data between the application layer and database. To avoid the need for dynamic memory restructuring during deserialization, the size required to store component data at each composite is stored when the composite is serialized, and during deserialization, the size is retrieved and used to obtain sufficient memory for the deserialized composite.
