AspOEv 项目的目标是提供一个面向方面的定制、扩展、交换对象数据库模型修改、结构化的方法。
The evolution framework being developed will be independent of the data model of the underlying object database management system but will be customisable to incorporate data model specific evolution primitives. A secondary aim is to employ aspects to provide customisable approaches for version storage (i.e. to flexibly choose between versioning-by-copy and versioning-by-difference) and database update (i.e. to flexibly choose between immediate and deferred update)
