船舶监控专用组态软件SQL查询实时数据库的实现

Design of SQL Query Real-Time Database in Ship Monitoring System Configuration Software

船舶监控专用组态软件遵循标准SQL语言规范,研发出了面向实时数据库系统的SQL查询技术。该软件沿用标准SQL查询的基本语句,利用SQL查询方法查询报警数据、实时数据、历史数据,大大提高了查询效率。其使用方法与标准SQL语言类似,会使用标准SQL语言就会用组态软件实时数据库SQL查询语言。

The real-time database SQL query technology is developed for ship monitoring specialized configuration software, fol- lowing the standard SQL language specification. To query alarm data, real-time data and historical data by standard SQL query statements greatly improves the efficiency of the query. Besides, the programmer who is familiar with the standard SQL lan- guage needs no further training for using the configuration software real-time database.
