工作流
工作流是在业务处理过程中每一步的任务、处理步骤、组织或相关人员、必须的输入输出信息以及需要的工具。分析和管理业务处理过程的工作流方法可以与面向对象的方法结合,该方法的注意力集中于文档、数据和数据库。一般来讲,工作流集中于管理处理流程而非文档。有些公司推出了工作流自动化产品,可以让一家公司生成工作流模型和诸如在线表单等部件,并使用这些产品来管理和实现一致的工作处理过程。Browser
A browser is an application program that provides a way to look at and interact with all the information on the World Wide Web. The word "browser" seems to have originated prior to the Web as a generic term for user interfaces that let you browse text files online. By the time the first Web browser with a graphical user interface was invented (Mosaic, in 1992), the term seemed to apply to Web content, too. Technically, a Web browser is a client program that uses the Hypertext Transfer Protocol (HTTP) to make requests of Web servers throughout the Internet on behalf of the browser user. A commercial version of the original browser, Mosaic, is in use. Many of the user interface features in Mosaic, however, went into the first widely-used browser, Netscape Navigator. Microsoft followed with its Internet Explorer. Today, these two browsers are highly competitive and the only two browsers that the vast majority of Internet users are aware of. Although the online services, such as America Online, Compuserve, and Prodigy, originally had their own browsers, virtually all now offer the Netscape or Microsoft browser. Lynx is a text-only browser for UNIX shell and VMS users. Another recently offered browser is Opera.本文出自:《电脑报》1999年05月31日第21期
