风洞测控系统的数据管理

汽车风洞是用来研究汽车空气动力学的一种大型试验设施，实际上是一个实验室，是一个大数据吞吐量的系统。数据库结构设计的好坏对实验的成败以及实验后的数据分析起着至关重要的作用。文章以风洞测控系统的数据管理为主要研究线索，进行了数据库结构设计过程中的各种方案优缺点比较，同时提出了数据库查询优化的部分方法。

The Data Management of Wind Tunnel Control System

Automobile wind tunnel is a large-scale experimentation establishment. It is a laboratory in fact. During the process of designing automobile, it need be tested in the wind tunnel laboratory for whichever change of any tiny component. There are all kinds of date produced unceasingly during the experiment. Users can choose the date which they are interested in to analyze and make comparison .By that they can get the testing output they want to get and make correct decision to improve the quality. In the face of such a system of large date throughput, the design of the database framework is good or not plays a important role in the success of the experiment and the analysis after it. This paper takes the date management of the wind tunnel control system as the major cue, make comparison of the excellence and defect of every project during the design process and put forward some method for the inquiry optimize of database.
