的數據訪問對象需要一個稱為The data access object pattern has become a standard part of the j2ee developer s arsenal
數據訪問對象( data access object )模式已經成為j2ee開發人員工具庫中的標準部件。As in the previous articles, i ll use a minimal model based on an online store, this time consisting of a basic product representation, a user s shopping cart that can contain product items, and a data access object to look up product details from a data store
像在前一篇文章中一樣,我將採用一個基於在線商店的最小模型,這次包含一個基本的產品表示、一個可以包含產品商品的用戶購物車以及一個從數據存儲查詢產品的數據訪問對象( dao ) 。You might have a web user interface view that s called by a controller, which calls a facade layer, which calls a data access object, which calls an object - relational mapper, which calls a database
您可能擁有一個由控制器調用的web用戶界面( ui )視圖,它調用外觀層,外觀層調用數據訪問對象,數據訪問對象調用對象關系映射,對象關系映射調用數據庫。First of all, the paper illustrates the concepts and the fundamental functions of gde. then it studies four primary problems. those are data model, data index, geographic data management and geographic data access objects
本文以地理數據庫引擎( geographydatabaseengine , gde )為研究對象,在描述了gde的概念和基本功能的基礎上,研究了gde四個主要方面的問題:數據模型、數據索引、地理數據管理以及地理數據訪問對象。In the case of data index, the paper generalizes several advanced data index at the present time and analyzes the feature of data index based on database emphatically. then it illustrates the spatial ordering quad - tree index based on database of gde. in the case of geographic data management, the paper studies and tests several primary technologies, such as data concurrent access, data storage, data query, data update and maintenance, data transmission and data buffer, and so on
數據模型方面,在對常見的數據模型進行描述和分析的基礎上,提出了滿足海量數據高效存儲和管理的gde數據模型,通過實驗對數據的存放方式和效率進行了測試;數據索引方面,歸納總結了當前提出的較為先進的幾種數據索引方法,尤其是著重分析了基於數據庫的數據索引的特點,並對gde基於數據庫的可排序四叉樹索引進行了重點闡述;地理數據管理方面,對數據並發訪問、數據查詢、數據更新與維護、數據傳輸以及數據緩存等關鍵技術進行了闡述和實踐;地理數據訪問對象方面,介紹了採用面向對象技術設計實現的地理數據訪問類。We ll begin with a review of the data access object pattern
我們將從回顧數據訪問對象模式入手。Simulated data access objects
模擬數據訪問對象Simulated data access objects essentially simulate a back - end datastore
模擬數據訪問對象實際上模擬後端數據存儲。Data access objects
數據訪問對象Data access object
數據訪問對象We ll start with a simple example of a simulated data access object, shown in listing 2
我們將從模擬數據訪問對象的簡單示例入手,如清單2所示:In part 2, you use ibatis s data access objects and data mapper to access an application s underlying data structure effectively. in this tutorial the jpetstore application
在第2部分中,我們將用ibatis的數據訪問對象( dao )和data mapper有效地訪問應用程序的底層數據結構。Three kinds of data access objects dao, rdo, ado and windows dna structure of three are discussed at length. integration mode of software system is summarized and a set of software is programmed on this basis to realize the database management of experiment data. in addition, another set of vod management system software is programmed to ensure its normal operation and effective management
本文回顧了數據管理方式的發展歷史,對數據庫,特別是sqlserver2000進行了比較詳細的介紹,討論了三種數據訪問對象: dao 、 rdo 、 ado ,詳細討論了windowsdna三層結構,對軟體系統集成方法進行了概述,然後在此基礎上編制了一套針對實驗數據的數據庫管理軟體,實現了對實驗數據的數據庫管理,另外還在導師原有科研工作的基礎上,進行理論分析,並改進編制了一套視頻點播管理系統軟體,實際運行證明,可保證視頻點播系統的正常運轉和有效管理。As is stated above, this thesis did research on struts, spring and hibernate frameworks, and analysed each framework ’ s function in web application layer. an architecture is integrated with the three frameworks which is suitable for enterprise web application. the architecture hands business logic of struts to spring ; utilize beans configuration to manage the related classes ; manage objects ’ relation of between controller and data access object through spring and make data persistence by hibernate. this thesis made did deep analysis and research on coupling of integration between spring and struts and put forward a solution to loose coupling of integration
本文針對上述問題,對struts , spring , hibernate框架進行研究,具體分析各個框架在web應用的不同層次上所發揮的作用,並整合三種框架,設計出一個適合企業web應用的java通用架構,即將struts應用中的業務邏輯交給spring管理,相關類用spring的beans配置完成,由spring管理與表現層的控制器及更下層的數據訪問對象( dataaccessobject )對象的關系,由hibernate負責數據的持久化;並對spring和struts整合的耦合性進行深入的分析研究,提出了一種框架整合的解耦方案;採用aop ( aspectorientedprogramming )機制,設計出一個脫離spring環境的aop ;最後用一個實際的項目對架構應用進行實現。Some, like velocity and middlegen, generate data access objects, given a description of the database tables
一些工具,像velocity和middlegen ,會生成數據訪問對象,給出數據庫表的描述。Use simulated and actual data access objects to effectively and efficiently test your j2ee apps
