城市地质领域信息管理与服务系统体系结构

城市地质信息管理与服务系统是面向城市地质领域的三维地理信息系统。该文从多元异构数据源集成管理、空间数据可视化、基础和专业数据分析、Web应用、数据共享和服务以及安全与认证等方面出发，分析了该应用领域的功能性/非功能性需求特性，并在此基础上讨论C/S, B/S, Pipe-and-Filter及工作流等常见软件体系结构模式与系统体系结构的适用程度，同时提出以3层C/S模式为主、B/S模式为辅的城市地质领域信息管理与服务系统的体系结构设计方案，使划分的功能构件具有较好的可复用性。实验结果表明，该方案是可行的。

Urban Geological Domain Information Management and Service System Architecture

Urban geological information management and service system is a 3D Geographic Information System(GIS) oriented to the urban geology domain. The functional and unfunctional requirements in this domain are analyzed, including the integrated management of multi-kind and multi-source data, spatial data visualization, basic and professional data analysis, Web application, data sharing and service and security & certification. Based on the requirements specification, several common software architecture patterns such as C/S, B/S, Pipe-and-Filter and work flow are discussed to find out how each pattern fits to the system architecture. Moreover, the scheme of system architecture with mixed 3-tier C/S pattern and B/S pattern is proposed, in which the components are reused at a high degree. Experimental results show this scheme is feasible.
