緩沖介面開關
英文
buffer interface switch-
Involuntarily, questions of these engineering datas " management appear, datas " persistance only depending relational model and rdbms is greatly insufficient, so this paper carefully studies object - relational mapping based on rdbms based on the analyse of home & overseas actualities, correlative theories and realizing methods of object - relational mapping, we find opl based on rdbms is the most suitable for object relatinoal mapping of clera. based on the engineering application analyse of opl in clera, function requirements, database modes, interface criterions and functions, running modes of opl have being detailedly described. with the framework of microsoft dna, a kind of realizing method of opl based on com / dcom / activex component technology has being brought forward, and this paper describes realizing keys from base tables " definition, object id and class hx class and inheritance of class, object storage, parallel control and affair, object query, object nesting, relations between objects, support of complex data types, right control of object and buffer management of object
本文在分析對象?關系映射技術的國內外現狀、相關理論及實現方法的基礎上，研究發現基於rdbms的opl是目前最適合clera的對象?關系映射方法；在clera的opl應用分析的基礎上，詳細描述了opl的功能要求、數據庫模式、介面規范與功能、運行方式等內容；結合microsoftdna開發框架，提出了一種基於com dcom activex組件技術的opl實現思路，並從基本表定義、對象標識與類標識、類與類繼承、對象存儲、並發控制與事務、對象查詢、對象嵌套、對象間聯系、復雜數據類型的支持、對象級權限控制及對象緩沖管理等幾方面概述了實現要點。In the chapter of component based database access agent, the component criterion for the agent is selected and the component frame of the agent is designed based on the discussion for the component development technology. in the chapter of the platform of network communication, its operational principle is discussed at first, then the program structure of the platform and the key technology of encrypted network transmission is focused. in the chapter of the design and implementation of the server of the agent, the operational principle is researched, the program structure is designed, and the key technologies of database flux control, data buffer, and database security are studied
基於組件的數據庫訪問代理設計介紹了組件開發技術、數據庫訪問代理的組件標準選擇及數據庫訪問代理的組件框架設計；網路通信平臺設計和實現研究了網路通信平臺的工作原理、實現過程中使用的基本技術，論述了網路加密傳輸關鍵技術，設計了網路通信平臺的程序結構；代理服務端設計和實現研究了代理服務端的工作原理，論述了數據庫流量控制和訪問優先級調度、數據緩沖及安全數據庫支持等關鍵技術，設計了代理服務端的程序結構；代理客戶端設計和實現研究了代理客戶端的工作原理，設計了代理客戶端的程序結構和組件介面。
