DataSet的数据并发异常处理

Data Concurrency Exception Handling of DataSet

DataSet是支持ADO.NET的断开式、分布式数据方案的核心对象.通过使用Data.Set减少了往返数据库服务器的巨大开销而提高了性能,但也带来了多个用户试图同时访问相同数据的可能性,由此引起数据并发性异常.本文分析了引起数据并发性异常的原因,并提出解决问题的方案.

The DataSet object is central to supporting disconnected, distributed data scenarios with ADO. NET. Using the DataSet improves performance by reducing expensive trips to the database server, it also introduces the possibility of multiple users attempting to change the same data simultaneously, thereby generating data concurrency exceptions. This essay analyzes the common reasons behind data concurrency exceptions and offers solutions for overcoming them.
