Multi-level disaster mitigation and relief information management method and system based on loose coupling mode

Abstract

The invention provides a multi-level disaster mitigation and relief information management method and system based on a loose coupling mode. The method comprises the following steps: acquiring all reserve warehouse material information of various administrative districts in China; carrying out division management on all the reserve warehouse material information through a pre-established reserve material database; and automatically inquiring the reserve material information in a skip-level manner by using a data fragment mechanism. Data are managed by the established reserve material database, data of different databases are matched automatically by the system, rapid big data query of data of physical databases of different administrative districts is implemented, and over-step-free management and cross inquiry are realized; personalized material management is realized; and by partitioned deployment, response time during query is shortened.

Description

technical field [0001] The invention relates to the field of computer information technology, in particular to a multi-level disaster reduction and relief information management method and system based on a loosely coupled model. Background technique [0002] The existing reserve management adopts a centralized mode or a separate mode. The centralized mode is to centralize all data in a physical database, and perform two-level correlation query on the reserve materials in different administrative divisions in the same warehouse. This mode The existing problem is that when the data grows geometrically, the performance problems of the system are more and more exposed. Finally, after the data grows to a certain scale, the basic performance of the system is basically unbearable and abandoned; the separation mode is two levels of different administrative divisions The data interface mode is directly adopted. When the upper-level reserve needs to query the material information of ...

Problems solved by technology

[0004] Aiming at the above-mentioned technical problems, the present invention provides a multi-level disaster reduction and relief information management method and system based on a loosely coupled model. The data is managed through the established reserve material database, and the system automatically matches different database data, which solves the physical problem of cross-administrative divisions. Big data fast query of database data, to achieve management without leapfrogging, query can be cross-level; realize personalized material management; partition deployment, reduce the response time when querying
