研究背景
当今时代是飞速发展的信息时代。在各行各业中离不开信息处理,这正是计算机被广泛应用于信息管理系统的环境。计算机的最大好处在于利用它能够进行信息管理。使用计算机进行信息控制,不仅提高了工作效率,而且大大的提高了其安全性。尤其对于复杂的信息管理,计算机能够充分发挥它的优越性。
对于社区管理和服务方面,虽然现在已经有利用信息技术运作社区管理和服务的例子,但大都处于起步阶段,有的仅仅是一些静态的网页设计或单纯的搬一些必需的表格上电脑,缺乏互动性,这些并没有很好的利用信息技术实现真正的社区管理和服务的自动化。因此为了解决这一问题,更好的为社区居民服务,选择开发本社区管理与服务系统。
在互联网的迅速发展下,局域网的普及,为建立社区管理与服务系统的设计与实现提供了基础条件。社区管理与服务系统与传统的社区管理与服务方式相比,有着无法比拟的优点,网络共享、传播速度快的特点,社区居民可以随时随地进入系统查询所需信息,同时管理员可通过计算机可对系统相关信息进行全面管理,更好的为广大社区居民服务。
研究现状
随着计算机的普及,信息技术也得到了空前的发展,计算机应用的领域也越来越广泛。提高处理事情的效率也已经成为了各行各业所追求的目标。
在国外,由于计算机发展的比较早,信息技术发展相比于国内更加快速,况且国外对于计算机系统应用的也是广泛。在国外社区管理与服务系统很早就已经开始进行实施了,而且效果相当不错。由于国外应用社区管理与服务系统的时间很长,所以使得他们在实际的工作中发现了计算机系统的不足之处,并将这些不足之处进行弥补。也是通过这些不足之出,国外的研究人员也逐渐制定了完善的规则和标准。并将其应用到社区管理与服务系统中。使得软件系统技术得到了长足的发展。
在国内,计算机普及的时间比较短,信息技术发展的还不是很完善,对于计算机信息应用的也不是很多,对计算机系统了解还不是透彻,导致计算机系统在实际应用中的实际效果与预期效果大相径庭,国内缺少的是解决计算机系统出现的问题的经验,因为对计算机系统的应用太少,国内缺少的是解决计算机系统所产生的问题的经验,想要社区管理与服务系统方面的研究水平得到提高,就要多遇到问题,然后解决问题,这样积累经验的速度才是最快的。
