Microsoft's COM is a software(1)that allows applications to be built from binary software components. COM is the underlying architecture that forms the foundation for higher-level software services, like those provided by OLE.COM defines a binary standard for function calling between components,a way for components to dynamically discover the interfaces implemented by other components,and a mechanism to identify components and their interfaces uniquely. OLE is a compound(2)standard developed by Microsoft.OLE makes it possible to create(3)with one application and link or embed them in a second application.Embedded objects retain their original format and(4)to the application that created them.Support for OLE is built into the Windows and MacOS Operating Systems.A(5)compound document standard developed mainly by Apple and IBM is called OpenDoC.
问答题
阅读以下关于Java企业级应用系统开发体系结构选择方面的叙述,在答题纸上回答问题1至问题3。
博学公司承担了某中小型企业应用软件开发任务,进度要求紧迫。为了按时完成任务,选择合适的企业应用系统开发体系结构非常重要。因此,首席架构师张博士召集了相关技术人员进行方案讨论,在进行方案论证时,项目组成员提出了两种开发思路。
(1)谢工建议采用J2EE和EJB进行开发。理由是J2EE定义了标准的应用开发体系结构和部署环境,EJB是J2EE的基础和核心。J2EE的主要目标是简化开发。
(2)王工建议采用Struts、Spring和Hibernate轻量级开源框架相结合的方式。理由是随着Java开源项目阵营的发展壮大,一些基于POJOs(PlanOldJavaObjects)的开源框架被广泛地引入到Java企业应用开发中来,与重量级的EJB框架相比,这些轻量级的框架有很多优点。
针对这两种思路,张博士仔细比较和分析了两种方案的特点、优点和不足之处。认为王工和谢工的建议都合理,但是,从结合当前项目实际情况出发,最后决定采用王工建议。
