用Javabean构建数据过滤的Script代码生成器

针对asp或jsp的客户端数据过滤程序代码由手工编写,编程效率低的缺点,提出了用脚本代码生成器实现自动生成数据过滤代码的方法。生成器的主要组件是Javabean,它可以连接到不同的数据库并操作数据表,在提取数据表的字段结构信息后,由用户选择需要过滤的字段,生成器能根据数据表的结构参数匹配bean中的相关过滤函数,最后生成具有数据过滤能力的客户端脚本代码文档。将生成器用于Web程序的开发,不仅能减少开发人员在编写、测试和修改代码工作量,而且能及时跟踪数据库(表)设计的改变,脚本代码生成高效、自动、准确。

基于XML的MARC元数据互操作的实现

MARC是图书馆界开发的一套高质量的数据描述元数据格式.MARC不能与Internet的信息分类和搜索服务之间实现互操作,MARC的互操作问题成为数字图书馆研究中的热点.基于XML的MARC元数据互操作的实现方式是:利用XML的DTD机制,定义一个MARC DTD,解决MARC元数据的XML描述问题;用XML元语言描述MARC元数据信息,并根据这些元数据信息建立相应的元数据信息检索数据库.这使图书馆现有的大量MARC格式的书目数据在Internet环境中得以充分的利用.

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
