What is the diffrence between low level design and high level design document. whether high level desgin (hld ) consist only class and sequence diagram. And a low level document(lld) consist each class thorough description which includes method and property name and every possible details. Also can anbody explain me diffrence between fine grained object and coarse grained objects ?
High level design means abstract view of the system ..... details are not shown... yes high level design does contain class diagram at conceptual level no operations are defined ...... while low level design uses class diagram at implementation level with most of the required detail.
I thing coarse grained refers too ... high level design and fine grained refers too ... low level design.

Yes, that's one way to look at it. At High-Level Domain Model and Detailed PDM I show examples of high-level and low-level data models. The issue is the amount of detail that you show. In the essay containing the two examples, I show how you start with high-level requirements and domain models and then evolve your design through six iterations.
A smart-aleck (or maybe practical) answer is that each artifact is whatever the reader asked for or needs. Who's reading it? What do they want to know? Why? Producing a document to some template so it can be filed forever is not much fun no matter how beautiful the doc.
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
