Data fragmentation is a badthing.. So you don't really want to have it happen. Are you talking about partitioning or clustering? Or avoiding fragmentation?

i think hes referring to horizontal, vertical and mixed fragmentation.

i myself have just come to grasps with this topic and find it difficult to understand it would be nice if their was a good website to explain distributed database design.

fragmentation is also linked to allocation as well so u might wanna have a look see at that.

other than this i would sugest looking into a book such as the very old distrubuted databases by ceri & pelagatti or for more uotodate book try connolly and begg which covers a chapter on dd.

So, to be clear, you are writing a thesis on fragmentation in distributed databases, but you don't know anything about databases? Isn't that a bit like writing a thesis on the use of transitive verbs in Greek when you can't actually read any Greek ;)

But anyway, relational databases are the ones that most people use like Oracle, SQL Server, MySQL. Object oriented databases were a fad a few years ago that seems to have withered away.
