Along with the coming of the national runt scientific and technical development planning compendium (2006-2020), the disaster prevention and reduction planning of the village and town areas is gradually paid attention, but because the disaster prevention and reduction planning of the village and town areas is started late and lacks of powerful support of related information technology, multi-source data is difficult to be efficiently integrated and managed, and the development and implementation effects of the disaster prevention and reduction planning of the village and town are influenced. Therefore, a data management system oriented to disaster prevention and reduction planning needs to be constructed, and massive, multi-source and complex data related to the disaster prevention and reduction planning of villages and towns are integrated and stored, so that a planner for disaster prevention and reduction of villages and towns or related researchers can obtain data results with consistent standards, uniform formats and high precision, and further the efficiency of the disaster prevention and reduction planning work of villages and towns is improved.
Data related to the disaster prevention and reduction planning of villages and small towns have the characteristics of multidisciplinary background, multiple formats, multiple sources and the like, and the data have certain geographic significance. When the integrated storage is carried out, the traditional data management method is challenged, on one hand, if the attribute table of the data is not subjected to uniform maintainability modification, the data management method will conflict with the data format of the bottom-layer relational database, and simultaneously, a large amount of data redundancy is brought, and the burden of data storage and data query is increased; on the other hand, if the data projection and the coordinate system are not unified, vector and grid data with geographic significance cannot be superposed and inlaid, so that the implementation of disaster prevention and reduction planning is influenced.
ArcSDE, an ESRI corporation in the United states, is a mature middleware technology that provides a spatial data engine that is reliable and supports multi-user concurrency. Based on ArcSDE and a spatial data model inside the ArcSDE, Geodatabase can realize the integrated storage of spatial data and non-spatial data on the basis of the existing RDBMS and realize multi-user concurrent transaction access to a bottom-layer database. The RDBMS is enabled to integrate storage for both spatial data and non-spatial data.
The Oracle database of the American Oracle company is one of the most widely used RDBMS at the present stage, has the characteristics of good portability and good performance, and has perfect log management and data recovery functions, so that the Oracle database has strong functionality and certain stability. The relational database mode adopted by the Oracle RDBMS is mature, the data redundancy is properly controlled, the data table retrieval is efficient, the data query speed is high, the data integration degree is high, and the storage management requirements of a large amount of data designed by the disaster prevention and reduction planning of villages and small towns are basically met.
