摘要

The Union Catalog (UC) of Taiwan was established to provide an integrated search service for millions of digital objects distributed in the databases of different institutions. The main challenge is how to continuously and consistently manage large quantities of data. XML technologies have already been recommended for greater data preservation rather than database systems. In addition, we assume that a database design in our case would be complex and that consistent maintenance would be difficult. For this reason, databases are not used as the primary storage mechanism of the UC. Although the UC adopts an XML-centric architecture, it has difficulty handling data queries, data modification, and category listing efficiently. In this paper, we discuss how we use XML technologies to implement the UC system, and how we solve the issues arising from XML's limitations.
