Abstract:
One of the key object-relational features added to relational database is
an extensible type system (ADTs). In this project, we examined in depth
how a real ORDBMS supports this feature by adding a useful new data type -
Email ADT into a commercial Object-Oriented Relational Database - NCR's
Teradata ORDBMS (TOR). This work involves two parts. Part 1, implementing
Email ADT, which consists of a source file, a header file and a XML
description file, supporting users to randomly retrieve different parts
from Email data. Part 2, integrating Email ADT into TOR, which includes
registering Email type, registering user visible functions to operate
Email type data, adding rules in parser, and updating build
script. Finally, we gave out our test cases for Email ADT in addition to
the original test case suites for existing data types in TOR and
corresponding results.
