摘　　要：针对系统中数据库产生的大量并发读的问题,提出了基于订购分发的数据读取解决方案。该方案采用了多种数据订购方式,跨越数据库及操作系统平台类型为应用软件提供所需数据。数据订购配置软件获取最新主题数据目录列表形成订购关系,订购关系以订单方式存储于数据库中并加以管理,订单状态可由用户在系统运行过程中进行激活和撤销。数据分发传输软件有效提高了数据传输的灵活性和可靠性,减少了数据库表的读取次数,提高了系统效能。Aimed at the problem of the mass database concurrent reading in the system, the data reading solution based on order and distribution is proposed. This scheme uses a variety of data ordering methods to provide the data for the application software across the database and operating system platform. The data ordering configuration software acquires the latest subject data catalog list to form the ordering relationship. The ordering relationship is stored and managed in the database as an order. The order status can be activated and revoked by the user in the system running. The data distribution transmission software can effectively improve the flexibility and reliability of transmission. And it can reduce the times reading database and improve the system performance.
