What is meant by "a series of deltas"?

I was going through a blog post by Dan Lew at Trello where he mentioned using a "series of deltas" to store changes made offline.

Can anyone explain me what is a "delta" basically. Any reference would help too.

Solution

  • I found the basic definition of a "Delta" by reading the tag description for delta in Stack Overflow.

    Its defined as: -

    A Delta is a file which represents the changes between two or more revisions of structured or semi-structured data

    So as far as my understanding, it is a file used to track the changes made to a piece of data.

    For example: -

    If client A changes a file with contents X to X1.

    Then the delta for this operation will be something like

    X -> X1 (Client A)

    Please do correct me if I'm wrong.
