The Application Research Of DM Database In The Population-based In Formation And Flood Control Management

DM database relational data model and standard mature based interface, is aacross a variety of hardware and software platform, database management systemwith large capacity, high efficient and stable data management. Relying on its strongfunction, high safety, complete high reliability of cluster, complete data replication,high performance, functional characteristics, ideal choice to become large enterprises,government departments and the security properties with higher requirements ofenterprises, institutions and other sensitive industries. DM database by thegovernment in2004(the first batch) database product catalogue.Study on the application of the technology industry in DM database can bemainly from two cases that;"Hubei Province Public Security Bureau population basicinformation database system" as an example: file data source access and data mergingfunction in data acquisition by data exchange program in the front database will bemerged into the front information database population basic information database;after the population basic information of public security department to lead thedatabase by data exchange platform for data exchanging, providing flexible datamigration through the filtering rule configuration tool is simple and easy to operate;then the data sharing, in order to ensure public security information security, reliableand authorized to use, does not allow non-public users directly into the securitydatabase data access; finally, data monitoring, statistics. Ensure public securitynetwork security, construction integration of scattered in various governmentdepartments to provide demographic information, data platform for e-governmentconstruction.On the other hand, in Inner Mongolia, the Yellow River ice flood controldecision support platform for example: with a docking, change data source, data ofeach subsystem in the end tracking program data change, through the configurationparameters to define the need to share the condition, will in fact when data is sent tothe subsystem, realizes the sharing in the second level data. Through the applicationof the above industry reflects the application of database in the promotion of greatsignificance for DM database to meet the data management and applicationrequirements.
