摘要

在分布式环境中协同编辑数据的能力在我们的信息化行业中是必不可少的。通常情况下,用户或系统出于不同的目的从不同的位置并发地访问和修改数据。每个目的都可能需要它自己的表示和共享数据的子集(例如,一个模型),以使编辑器具有生产力。因此,形成了一个多模型的系统,这需要多向同步。虽然有一些方法可以实现这样的系统,但是没有一种方法支持并发修改。为了克服这一限制,我们用一种新的冲突检测和解决方法扩展了先前在面向角色的模型同步方面的工作。面向角色的编程已被证明是实现多模型系统的适当范例,因为它在对象协作级别提供了关注点分离,并允许表达与上下文相关的行为。我们使用一个员工数据管理案例研究来评估我们的方法,并评估引入的性能开销。

Resolving synchronization conflicts in role-based multimodel-synchronization environments
The ability to collaboratively edit data in distributed environments is essential in our information-based industry. Typically users or systems concurrently access and modify data from different locations for different purposes. Each purpose might require its own representation and subset of the shared data (i.e., a model), for the editor to be productive. Consequently, a multi-model system results, which requires multi-directional synchronization. Although some approaches exist to realize such systems, none of these supports concurrent modifications. To overcome this limitation, we extend previous work on role-oriented model synchronization with a novel conflict detection and resolution approach. Role-oriented programming has been shown to be an adequate paradigm to realize multi-model systems, as it offers separation of concerns at the level of object collaborations and allows to express context-dependent behavior. We evaluate our approach using an employee data management case study and assess the introduced performance overhead.
