SOA中间件平台通常采用文本压缩方式进行日志消息存储,因此标准功能无法实现对消息内容的搜索。而采用完全定制开发接口日志方式,虽然可以实现对消息内容的检索,但会大大增加接口开发工作量和后期维护成本。本文以SAP PI中间件平台为例... SOA中间件平台通常采用文本压缩方式进行日志消息存储,因此标准功能无法实现对消息内容的搜索。而采用完全定制开发接口日志方式,虽然可以实现对消息内容的检索,但会大大增加接口开发工作量和后期维护成本。本文以SAP PI中间件平台为例,介绍了一种通用SOA中间件平台日志消息检索实现方法,能够以较少的工作量实现对消息内容的灵活检索。 展开更多

We studied the information search behaviors of Chinese consumers of miniature automobiles. First, we identified the main sources where consumers acquire or seek information about miniature automobiles and discussed their extent of information search. Then, based on logistic regression and optimal scaling regression of statistics, we studied the influences of characteristics of consumers of miniature automobiles on the extent of information search and on Internet usage. The results indicate that consumers often utilize four sources to obtain information about miniature automobiles. The dominant information source for consumers is their friends/family, followed by dealers, newspapers, and TV. Age, occupation, education and income significantly affect the extent of information search, but gender and city of residence do not have significant impacts. Age, city of residence, occupation, education and income produce significant influences on Internet usage. Gender has an insignificant influence on whether a consumer uses the Internet to search for information. 展开更多
