【摘要】：上个世纪90年代当智能小区的概念首次在国内提出后,便得到了公众的广泛关注。但是,基于对技术,投资及市场等方面因素的综合考虑,现有智能小区很少可以做到真正的“智能”。主要表现为小区中存在多个管理子系统,而又缺少一个公共的管理平台对小区进行高效的统筹管理。因此,本文提出了通过异构数据库整合技术,将小区中已有的、独立的子管理系统进行集成。在保证对现有投资的充分利用前提下,建立一套高效实用的智能小区管理系统完成小区日常事务的管理。智能小区管理系统集成的核心实质上是异构数据库的集成,而日益成熟的XML和Java技术为异构数据库集成提供了一条可行的方案。因此在数据库集成方面,本文采用以XML文档作为数据的组织形式,使用Java完成对数据的操作,建立一套B/S体系结构的智能小区管理系统。与传统的B/S体系结构相比,为了实现对异构数据库的处理,该设计在原有的三层构架的基础上加入了一个由元数据、分解合并器和查询器组成的中间层,通过该中间层用户可以与数据库层进行很好的无缝连接以及对数据库进行透明访问。通过论证,该系统可以有效的完成对异构数据库的各种操作,达到智能小区管理系统对于应用的需求。通过系统的集成,使得智能小区朝着“智能”目标又迈近了一步。
[Abstract]:In -10s, when the concept of intelligent community was first put forward in China, it got wide public attention. However, based on the comprehensive consideration of technology, investment and market, etc. The existing intelligent community can rarely achieve true "intelligence". The main performance is that there are many management subsystems in the community, and there is a lack of a common management platform to efficiently manage the community. In this paper, the integration technology of heterogeneous database is proposed to integrate the existing, independent sub-management system in the community to ensure the full use of the existing investment. Set up a set of efficient and practical intelligent district management system to complete the daily affairs management. The core of intelligent community management system integration is the integration of heterogeneous databases. The increasingly mature technology of XML and Java provides a feasible solution for heterogeneous database integration. Therefore, in the aspect of database integration, this paper uses XML document as the organization of data. Java is used to complete the operation of the data, and a set of intelligent community management system with B / S architecture is established. Compared with the traditional B / S architecture, in order to deal with the heterogeneous database, the design adds a middle layer composed of metadata, decomposer and query on the basis of the original three-tier architecture. Through this middle layer, users can connect seamlessly to the database layer and make transparent access to the database. Through demonstration, the system can effectively complete all kinds of operations to the heterogeneous database, to achieve the intelligent community management system for the application needs, through the integration of the system. Make intelligent community toward the "intelligent" goal to take a step closer.
