智能数字相册系统的设计_毕业论文.doc

I摘 要随着计算机和数码设备的普及，数字图片资源已成为我们日常生活中的一个重要部分，对于日益增多的图片资源，如何更好的存储和有效检索已成为人们面临的一个新的课题，于是电子相册应运而生该系统和一般的数字相册系统相比，更具有一定的智能性例如：当用户需要某幅相片时，可以通过简单的人机交互，或者根据用户的使用记录，自动推荐出用户可能需要的图像本文介绍基于.NET平台开发的基于B/S模式的智能数字相册的具体实现系统的主要开发语言为C#，应用了XML、Ajax等技术，结合了目录管理与SQL Server数据库管理同时采用基于文件方式的图像存储，即图像文件以文件形式存放于指定的计算机目录下，在数据库表中只反映图像数据文件的存储路径及各种属性，这种存储方式缩小了数据库的容量，对图像的操作和使用都十分方便对于数字相片的录入，检索等功能的实现，系统采用了当今流行的Ajax技术，其改变了传统的客户端与服务器端交互的方式，使得用户无需等待数据刷新，即可执行其他的操作，所有的数据处理都在后台进行，提高了用户体验系统的主要功能包括：用户登录与用户管理、图像的导入和显示，根据关键字检索图像，根据图像的分类浏览相册及改变相册的风格。

As for the growing number of images, how to keep and retrieval them effectively is the facing problem. As a result, e-album came into being. Compared with other e-albums, this new system attend to be more intellect. For example, if you want to find out one picture from the album, you could choose to contact with your computer. Also, you could wait the system to recommend according your records, then you will find out the image you want. At the same time, if you want to look though some related pictures, you could input some keywords, then your pictures will come into being immediately.This paper will introduce you the intelligent e-album, which is developed with B/S model and is based on .NET platform .The e-album is developed in C# language, applied with XML and Ajax technology, combined with the management of catalogue and SQL Server. Pictures in the e-album are storaged based on files, that is pictures are storaged at the given catalogue as files not images. At the same time, only the storage location and attributes of pictures are written in the database, which makes the database smaller .Therefore, it is convenient to users. For the loading and retrieval, Ajax is used in the e-album. This most popular technology changes the traditional pattern between client and server, allowing replacing data without renewing the whole page. All the processing work is done in the background, which is quite convenient to users.The e-album includes the login and management of users, the import and display of images, searching images according to some key words. Looking though pictures of diffirent catalogy is also included.Key words: Ajax; .NET; E-albumIII目 录1 绪论绪论.....................................................................................................................................11.1 研究的意义及目的.......................................................................................................11.2 国内外文献综述...........................................................................................................11.3 研究内容.......................................................................................................................12 相关技术相关技术.............................................................................................................................22.1 AJAX技术概述..............................................................................................................22.1.1 Ajax 技术的含义...................................................................................................22.1.2 Ajax 技术的特点...................................................................................................22.1.3 Ajax 开发的关键技术...........................................................................................22.2 .NET FRAMEWORK.........................................................................................................42.2.1 .NET 框架结构......................................................................................................42.2.2 ASP.NET 技术.......................................................................................................42.2.3 ASP.NET 命名空间...............................................................................................52.2.4 ADO.NET 技术 .....................................................................................................62.3 本章小结.......................................................................................................................83 智能数字相册系统的设计智能数字相册系统的设计.................................................................................................93.1 总的设计目标...............................................................................................................93.2 需要解决的重点问题...................................................................................................93.3 系统数据结构的设计.................................................................................................103.4 系统功能设计.............................................................................................................103.4.1 图片管理..............................................................................................................113.4.2 图片检索 ......................................................................。
