Research on Modeling of Flight Parameters Data Warehouse
Wan Ming · Modern Electronics Technique · 2010
According to the practical problems that the departments of aircraft maintenance are faced with such as great amount of flight parameter data,and low capability of data analysis and processing which caused numerous data to be turned into information trash,the flight parameter data warehouse model is brought up,as well as the concept model,logical model,physical model,metadata model and granularity model of flight parameters.The existing physical model was improved by combining RAID 5 technology with data warehouse physical model theory.As a result,the store device reliability was enhanced and the system response time was shortened.
