This paper makes researches on pdm ' s kernel function - pcm ( product configuration management ) under the conditions of autocad and low - price dbms witch could be acceptable in our middle or small factories. this paper mainly discusses the recursive query algorithm based on general database witch is offered in oracle, the problem of the automatic bom maker for autocad and conversion from bom to product structure trees. thus the data of autocad files could go into erp ( enterprise resource plan )
本文從pdm理念出發，在我國中小企業普遍能接受的autocad和低價位數據庫管理系統的平臺條件下，對pdm的核心技術模塊pcm （產品結構管理）的實現進行了研究，重點解決了在一般數據庫中實現數據庫系統oracle中具備的遞歸查詢演算法， autocad環境下bom表的自動生成技術，以及bom表向產品結構樹的轉化問題，從而使cad數據通過bom表的橋梁作用進入erp （企業資源計劃）系統。
