使用多层体系结构设计与开发酒店预计系统

摘要

Web站点正在快速成为旅游业的重要营销环境.传统的基于2种模型的应用表现出许多弱点,比如应用开发与维护代价太高.多层体系结构有助于解决这些问题.在基于多层模型的应用中,商务逻辑功能介于用户接口层和数据存储与管理层之间.基于这种方法的应用开发具有许多优点,比如可复用性、灵活性、可管理性、可扩展性和增强的安全性.介绍使用多层体系结构设计与开发酒店预订系统的过程.本系统使用Microsoft Visual Basic作为开发工具,Visual InterDev 为应用程序的开发平台,使用Microsoft SQL Server作为后台数据库服务器,网页的开发则采用HTML和VBScript.本系统使得客户可以在线预订不同类型的房间,维护客户信息,以及跟踪客户入住或离店的情况.%The website is quickly becoming a critical advertising and marketing presence for an adventure tourist business.The traditional two-tier model shows striking weaknesses that make the development and maintenance of applications much more expensive.Multi-tier architecture endeavors to solve these problems.With multi-tier applications,the client provides only one layer,I.e.,the user interface.The business rules are performed on a system between the user interface and the data storage.Using this approach,a number of benefits during the application's life cycle can be achieved,including seusability,flexibility,manageability,scalability,multi-language support and improved security.This paper deals with the design and implementation of an online hotel booking system with multi-tier architectural approach.The system uses Microsoft Visual Basic for desktop application and Structured Query Language (SQL) Server,HTML with VBScript and Active Server Pages (ASP) for the web application.The system enables the prospective guests to book different types of rooms online,keeps the database on guests,tracks when guests check in or check out and issues voucher at the time of checking out.
