基于Visual C＋＋的水声目标数据库设计

针对水声目标实测数据量庞大，LOFAR和DEMON分析计算量大的问题，设计了一个基于Visual C＋＋6．0的数据库管理系统。管理系统通过ADO接口实现与SQL Server 2005数据库管理程序的数据交换，保证了数据稳定存储和高效传输。通过内存映射文件技术，实现了对大数据文件的快速读取。采用CPU与GPU并行计算进行了LO-FAR和DEMON分析，实现了LOFAR和DEMON谱图的实时显示。整个数据库管理系统操作简洁高效，可靠性高，具有广泛的实际应用价值。

Database Design of Underwater Acoustic Target Based on Visual C++

To deal with large amount of underwater acoustic target measured data and large amount of cal-culation of LOFAR and DEMON,a database management system based on Visual C++6.0 was designed. The system exchanged data with SQL Sever 2005 database management program through ADO interface in order to ensure a stable storage and efficient data transmission.The system read data using memory map-ping file,which can improve the efficiency of file read.The system analyzed LOFAR and DEMON using parallel computing based on CPU and GPU,which can real-timely display the spectrogram of LOFAR and DEMON.The system designed concisely,efficiently and of high reliability,which has extensive practical application value.
