【Abstract】 Bill of Material ’s structure is introduced. A single- layer BOM model’s implementation is discussed in relational database, and a query method is proposed to reconstruct products’ model tree. Six kinds of BOM views are discussed about their structure、 differences 、 and relations. A multi- views mapping model based on single- layer BOM is proposed. The multi- views model’s mapping processes are analyzed and implemented.更多还原
