XML, proposed by W3C, becomes a new media for data exchange and is applied widespread on the database fields. Many research for data conversion by XML focus on the relational databases. Some papers propose the data conversion between hierarchical data model. It is necessary to establish data with many-to-many relationship among the ordinary business data. However, data with many-to-many relationships can not be represented the by hierarchical data model. The network data model (NDM) can satisfy this characteristic. In our research, we propose six data conversion algorithms in a data exchange model. By the six algorithms, the enterprises and organizations which use the NDM-based database can exchange their business data by XML documents. The XML documents keep the relationships among data in the database. XML Schema or DTD is used to preserve the overall structure and data types of data, to avoid the unpredicted errors during the process of data conversion. Experiments are performed to analyze the performance of the proposed model. Jeang-Kuo Chen 陳靖國 2005 學位論文 ; thesis 75 en_US |
