If any part of that frame is changed (hence 'reframing'), then the meaning that is inferred may change. To reframe, step back from what is being said and done and consider the frame, or 'lens' through which this reality is being created.

In computer science, shadow paging is a technique for providing atomicity and durability (two of the ACID properties) in database systems. A page in this context refers to a unit of physical storage (probably on a hard disk), typically of the order of 210 to 216 bytes. Shadow paging is a copy-on-write technique for avoiding in-place updates of pages. Instead, when a page is to be modified, a shadow page is allocated. Since the shadow page has no references (from other pages on disk), it can be modified liberally, without concern for consistency constraints, etc.
