- in addition, it analyzes and compares the implementation approaches and mechanisms of oracle spatial and arcsde, which are the two techniques to manage spatial data based on the pattern . thirdly, it respectively expounds the features and architectures of spatial data warehouse and distributed spatial database, concludes that they are uniform in reality although they seems to be opposite and then presents a model of distributed spatial data warehouse . finally, taking the construction of spatial data warehouse in the project of " digital fujian " as an example, it puts forward the scheme to implement data integration of spatial data warehouse
<中文摘要>=本文围绕着空间数据仓库的数据集成的几个问题展开讨论：首先讨论了组织数据仓库不可避免的属性数据的异构性问题，给出了异构数据库的数据转换方法；接着，针对采用基于对象-关系模式的数据库管理空间数据的方式，讨论了其特点和实现策略，并就在该模式上实现空间数据管理的两种技术oraclespatial和arcsde的实现途径和机制进行了比较和分析；然后，分析了空间数据仓库和分布式空间数据库的特点和体系结构，并对二者看似对立实则统一的关系进行了分析，提出了分布式空间数据仓库的一种模型；最后以“数字福建-政务共享平台统计局专题信息改造工程”的空间数据仓库建设为例，给出了空间数据仓库的数据集成的实现方案。 - secondly, apart from the spatial character, the operational data of sea area use management are characterized by multi-source, multiple scale, and coordinate, complex type and large quantity, etc, so this paper has laid emphasis on studying the spatial data model and the data framework related to the management of sea area use, solved a series of key technical problems such as check and correction, organization and structrue, quality management and standard norms for the geographical sapce data associated with the management of sea area use, proposed various practical and effective ways of storing and managing spatial and non-spatial data and established the spatial data base system for the management of sea area use
其次，由于海域使用管理业务数据除空间特性外，还具有多源、多尺度、多坐标、类型复杂、数据量大等特征，因此，本文重点研究了与海域使用管理相关的空间数据模型与数据框架，解决了海域使用管理相关地理空间数据的复合与订正、组织与结构、质量管理与标准规范等一系列关键技术问题，并提出了切实有效的空间数据和非空间数据的不同的存储、管理方式，建立了海域使用管理空间数据库系统。
