变更集模型与快照模型。
在快照模型中，可以快速获得修订，但需要更多的空间来存储它们。
In the snapshot model, you can get revisions quickly, but you need more space to store them.
在快照模型中，整个存储库的每个修订(带优化以减少树的大小)的全部文件都被存储。
In the snapshot model, complete files are stored for the entire repository for each revision (with optimizations to reduce the size of the tree).
与CVS一样，Subversion也是一种集中化的解决方案，采用的是快照模型。
Like CVS, Subversion is a centralized solution and USES the snapshot model.
选择输入逻辑模型和输出文件夹，如下面的屏幕快照所示。
Choose the input logical model and the output folder as shown in the screenshot.
或者，如果系统具有数据模型，那么根据此定义，资源表示形式是系统的数据模型中的对象之一的属性快照。
Or, if the system has a data model, then according to this definition a resource representation is a snapshot of the attributes of one of the things in your system's data model.
为了最小化必须应用到基本修订的修补的数量（根据变更集模型），cacherev命令将会在存储库中创建基本修订的一个新的快照。
To minimize the number of patches that must be applied to a base revision (per the changeset model), the cacherev command will create a new snapshot of the base revision in the repository.
您需要两个模型来管理快照。
此款软件利用重叠快照构造实景3D模型，可以旋转并从各个角度观看。
The software uses overlapping snapshots to build a photo-realistic 3-D model that can be spun around and viewed from any angle.
MDD正遭受两方面限制：首先，模型业务逻辑代表一个瞬间(point - in - time)快照，在人们将其翻译成代码的过程中，存在很多人们必须填补的空白。
MDD is suffering from two limitations. First, the model represents a point-in-time snap shot of the business logic, there are many gaps that people have to fill as they translate it into code.
图3显示了一个屏幕快照，清单3则包含了此模型的输出。
Figure 3 shows a screenshot, and Listing 3 contains the output from this model.
图2是某个业务流程模型的快照，该模型是用WebSphereBusiness Modeler创建的。
Figure 2 is a snapshot of a business process model created using WebSphere business Modeler.
在EMFV2.5之前，正如上面的几个屏幕快照所示，从一个扩展了的Ecore模型生成的具体模型应该保留 '.ecorex'的扩展名（如创建时的向导所建议的那样）。
Prior to EMF V2.5, as shown in several screenshots above, a concrete model produced from an extended Ecore model could keep the file extension '.ecorex' (as proposed by the wizard at creation time).
