  1. 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。
  2. This paper decomposes materialized views maintenance into ods / db interface and dw / ods interface. multiple data sources with concurrent updates may result in update anomalies of the materialized views. so at ods / db interface this paper introduces an improved nested transaction model - based transaction concurrency control mechanism to maintenance views in ods on line

    本文把視圖的一致性維護問題分解到三層結構的ods / dw和dw / ods兩個介面上分別實現，並且引入視圖生成樹的概念，在ods / db介面處採用基於改進嵌套事務模型的並發控制機制，聯機維護ods的數據，大大提高了視圖維護過程中的並發度和靈活性。
  3. But at present, there seem to be much deficiencies on the correctness and reliability of workflow and it can not meet the practical needs very well. in this paper, we introduce some transactional properties to workflow and put forward a nested workflow model with transactional characteristics. this model includes nested tasks and dependencies between the tasks, and it is provided with some atm properties such as relaxed isolation and atomicity. further more, we discuss the execution mechanism, system recovery and error handling of workflow on the base of the transactional characteristics. by defining consistency unit and execution atomic unit, we loosen the failure atomicity, serializability of concurrent worflow and isolation between tasks, thus, workflow meets the needs of the application semantics more flexiblly with high correctness and reliability

    這個模型包含嵌套任務和任務間的依賴，並具有高級事務模型的一些屬性，比如鬆散的隔離性和原子性。我們又進一步在這個模型的基礎上利用這些事務性質提出了有關工作流的執行機制、系統恢復和錯誤處理等問題的解決方法。通過定義一致性單元和執行單元放鬆了事務的失敗原子性、並發工作流的可串列化要求以及任務間的隔離性，使工作流在具有高可靠性和正確性的前提下更靈活地滿足實際應用語義的要求。
