Technical Field
The invention belongs to the technical field of ecological hydrology, and particularly relates to a hydrology data access control system.
Background
With the increasing of hydrologic data volume and the expanding of business, a series of problems are exposed in the aspects of data security, access efficiency, data sharing data service and the like, the existing data management and service mode cannot meet the urgent requirements of hydrologic modernization development, and the change of the existing data and business service mode is very necessary and meaningful. At present, a hydrological data monitoring system is transited from wired monitoring to wireless monitoring so as to solve the problems of high cost and high difficulty of wired deployment of hydrological monitoring ground data acquisition nodes. On this basis, most of the multi-authority access control mechanisms in the existing wireless hydrological data monitoring systems adopt the method that a single-instance SQL Server access control database is established in a management control center, and each user sends an access request to the control center to obtain corresponding database matching items and a hydrological data query result. Once the access control requests of users with different access rights are too large, the access is slow, and even the database system is crashed, other business systems based on the database system cannot access the database.
