Hi Kevin.M.Stoffel,

感谢您在此发帖。

每次签入更改时，它们都会作为更改集存储在服务器上。变更集包含版本控制中每个项目的历史记录。当然，您可以回滚到您想要的任何变更集，请参阅以下链接：

Each time you check in changes, they are stored on the server as a changeset. Changesets contain the history of each item in version control. Of course, you could roll back to any changeset you want, please refer to the following link:

I我不熟悉SQL事务，如果源控件中的文件发生了这种变化，那么TFS可以将更改记录为变更集 检查更改后。如果误解了您的意思，请更详细地描述您的问题。

I am not familiar with the SQL transaction, if this change happen to the file in source control, then TFS could record the change as changeset  after you check in the changes. If is misunderstand your meaning, please describe your problem in more detail.

***的问候
