摘要

系统工程师正在使用面向对象的企业组件来集成和提供对遗留信息系统和数据库的访问。这些组件可以将遗留系统的一部分数据和功能提供给新的应用程序(包括内部网和外部网)，从而延长遗留系统的使用寿命。然而，遗留系统的可用性通常不能满足这些新应用程序的需求。本文提出了一种迁移到企业组件的策略，该策略通过以本机对象形式存储组件数据来提高遗留功能和数据的有效可用性。它建议使用嵌入在组件执行环境中的持久性服务来存储持久性企业数据。它将这种方法与其他方法进行比较，并将这种战略应用于指挥和控制系统的初步经验联系起来。

Persistent enterprise components: improving the availability of legacy systems

Systems engineers are using object-oriented enterprise components to integrate and provide access to legacy information systems and databases. These components may extend the useful lifetime of a legacy system by making a subset of its data and functionality available to new applications, including intranets and extranets. However, the availability of the legacy systems often does not meet the requirements of these new applications. This paper presents a strategy for migration to enterprise components that improves the effective availability of legacy functionality and data by storing component data in native, object form. It proposes the use of persistence services embedded in the component execution environment to store persistent enterprise data. It compares the approach to alternatives and relates the initial experience in applying this strategy to command and control systems.
