The invention provides a structured query system for key value pair data storage. The system comprises an alarm application end function module, a JDBC driving function module, and a redis memory database. The alarm application end function module comprises an alarm centralized showing assembly, an alarm acquisition assembly, a knowledge enriching assembly, and an alarm bottom layer acquisition assembly. The alarm application end function module is connected with the JDBC driving module. The JDBC driving function module is used as a bridge of the alarm application end function module to read the redis memory database, and is connected with the redis memory database. The redis memory database is used as a supporting body of alarm data, and a front end queries the memory database through the JDBC driving function module, so as to realize correlation analysis of real-time alarm information. The system solves technical problems in the prior art that system development and maintenance costs are relatively high since a memory database is used to support large amount of data of an alarm system, but mainstream memory databases at present mostly use self-defined API interfaces to integrate with an application system, not following a SQL interface, and the mainstream memory databases are not beneficial for integrating with external system.
