By the browser / web server / database structure and the technology of asp. net and xml, we achieve the expert system running on the network, extend the application and ensure its backward compatibility ; we have the deep research to the representation of knowledge and apply it to the system, extend the traditional method of rule based knowledge representation ; introduce the fuzzy sets, analyze the generalized possibility interval sets, and combine the linguistic variables and fuzzy sets ; the system adopts the forward and backward chaining, researches the reasoning under uncertainty and inexact reasoning ; and we depart knowledge base and inference engine, make the upgrade simple and maintenance convenient. in the last, we construct the potato produce manage system according to the phases of potato ' s growth to give a detailed instruct to its produc e
Net和xml技術，實現了網路化的專家系統，同時擴大了專家系統的應用范圍，提高了系統的後向兼容性；對專家系統中的知識表示技術作了深入探討，在傳統的基於規則的知識表示方法的基礎上，提出了基於規則擴展的知識表示方法，並較好地將其應用到本系統中；引入了模糊集合，分析並推導了廣義可能區間集，將其應用於模糊知識的表示，將語言變量和模糊集合結合起來；提出對系統採用互動式知識獲取途徑、雙向推理控制策略，對不精確推理和不確定性推理的傳播演算法作了一定的研究，成功地將其應用到馬鈴薯專家系統的構建之中；採用知識庫和推理機相分離的方法，使得系統升級簡單易行。 -
I study mainly the storage of record and object, and bring forward the method of storage when the instance of object is embodied inside of record. 3 ) in the aspect of indexing, i presented a method that is generalized b - tree ( gbt ) and combining technique of founction template of c + + build the universal algorithm of queries, insert and delete. 4 ) finally, i analyze deeply and improve the query processing system of ormdbms, and confirm performance algorithm of linking and queries based on relational database. management system ( rdbms )
在系統結構和特性中分析了系統所採用的兩層體系結構，並且詳細探討了在設計和實現數據庫時所涉及到的幾個主要問題：支持復雜對象、類型擴充、繼承機制和規則系統等；在存儲機制的討論中，主要研究了記錄和對象以及包含了對象實例記錄的存儲方法；在索引技術研究中，本文提出了類屬b樹的索引方法，通過c + +的函數模板技術給出了通用類屬b樹查詢、插入及其刪除的基本演算法；最後，文章以關系數據庫為基礎，深入分析並改進了在對象關系多媒體數據庫中的查詢處理系統，確定了選擇和連接操作的具體演算法。 -
