Abstract

: Population growth and rapid urbanization have caused an exponential increase in urban land demand in Ethiopia. The information required for land administration and management has been tremendously increasing as well. Therefore, this paper describes the steps for a building database prototype for urban land information management system for the case of Ethiopia which results to develop an efficient and effective way of spatial and non-spatial urban land data management system. This research project will develop a central database system using a PostgreSQL software to retrieve, update and store the required data using a user-friendly graphical interface. System requirement and specification is devoted to a system design which incorporates the intended system behaviour using a use case diagram, logical design of the system using a class diagram. The design system is validated and tested via sample data which can store, retrieve, and update the required data as per the user requirement. Developing this type of urban land information management system, therefore, facilitates and increases the efficiency of land registration and related activities at the municipality level. Thence, citizens would be satisfied by the service delivery of the municipality. The land and real estate ownerships registration will also become automated. Furthermore, any spatial and non-spatial data related with the system can be stored in the database which will be ready for more analysis as to be able to use by policymakers, urban planners for the purpose of sustainable development of urban area infrastructural developments and land use policy. The research will lay ground for another task to develop CityGML 3D modelling for selected cities thereby contributes to spatial data infrastructure development to Ethiopia.

PostgreSQL中城市土地信息管理系统的构建——以埃塞俄比亚为例
:人口增长和快速城市化导致埃塞俄比亚城市土地需求呈指数级增长。土地管理所需的信息也在急剧增加。因此,本文以埃塞俄比亚为例,描述了建立城市土地信息管理系统数据库原型的步骤,从而开发出一种高效、有效的空间和非空间城市土地数据管理系统。该研究项目将使用PostgreSQL软件开发一个中央数据库系统,使用用户友好的图形界面检索、更新和存储所需的数据。系统需求和规范专门用于系统设计,该设计使用用例图结合了预期的系统行为,使用类图进行系统的逻辑设计。设计系统通过样本数据进行验证和测试,样本数据可以根据用户需求存储、检索和更新所需数据。因此,开发这种类型的城市土地信息管理系统,有助于提高市一级土地登记和相关活动的效率。从那时起,市民将对市政当局提供的服务感到满意。土地和不动产所有权登记也将实现自动化。此外,与该系统有关的任何空间和非空间数据都可以存储在数据库中,该数据库将随时准备进行更多分析,以便决策者、城市规划者能够使用,以实现城市地区基础设施发展和土地利用政策的可持续发展。这项研究将为另一项任务奠定基础,即为选定城市开发CityGML 3D建模,从而为埃塞俄比亚的空间数据基础设施开发做出贡献。
