hi, in my application ( kind of wiki clone ) - an article is frequently changing.

and i need to track all changes that are done on that article. { text only. }

one crude way i have done it, is to add a datetime property and create a new entity everytime something change. which is too much database wasting. { and also un-necessary index waste too. } and also need to re-create parent-child and entity relationships.

i also have log which can show changes -- but i want some thing easier , so that jumping from one version to another version could be easier.

ideas ?

thanks.
