System Low Level Design
A good low level design document makes the program easy to develop when proper analysis is utilized to create a low level design document.
System low level design. It defines the actual logic for each and every component of the system. Details are not shown. Class diagrams with all the methods and relation between classes comes. Low level design summary requires an exploration of the implementation alternatives stepwise refinement is a general problem solving approach investigate each alternative until the best approach becomes clear or resources demand that you make your best guess plan for future change if this choice must be revisited.
Low level design lld is like detailing the hld. It gives more specific guidance for how the parts of the system will work and how they will work together. Low level design fills in some of the gaps to provide extra detail that s necessary before developers can start writing code. Detailed system design 3 1 super nodes 3 1 1 design description this service keeps an inventory of the set of centroids which are used in the system.
There might be more than one centroid in a set. While low level design uses class diagram at implementation level with most of the required detail. The centroids are locations with co ordinates. Yes high level design does contain class diagram at conceptual level no operations are defined.
The code can then be developed directly from the low level design document with minimal debugging and testing. I thing coarse grained refers too. Other advantages include lower cost and easier maintenance.
