HLD:
High Level Deign is the overall system design --
covering the system architecture and database design. It
describes the relation between various modules and
functions of the system. data flow, flow charts and data
structures are covered under HLD.Acceptance
Testing is used in this design process.
LLD:
Low Level Design is like detailing the HLD. It
defines the actual logic for each and every component of
the system. Class diagrams with all the methods and
relation between classes comes under LLD. Programs specs
are covered under LLD.Unit and Integration Testing is used
in this design process.

Answer / tj.valiyamattam
HLD:
High Level Document is the Document which is explaning the
client need and expected system. It will cover the existing
system, issues with the existing system, goal of the new
system, SRS,Patern and architecture to be used, Technology
and tools to be used for the development and testing, DB
diagram, protocols to be used, data communication criteria,
modules to be developed. An HLD will be an input to the
LLD. This document can be used by a tester before
acceptance testing.
LLD:
Low level documnt will be divided as modules as per the
HLD. Each modules should again divided as functionalities.
Each functionality document will have the functionality
head, Whole desciption of the functionality, Controls to be
used and naming conventions to be followed, to or from
dependancies (how to activate this functionality and the
output after this functionality), DB objects which
afecting, DB objects to be used, A screen shot of the GUI
(look and feel), And the expected result of the
functionality. A tester can do the integration testing
based on the LLD.

that are used in a project.
Low level design:
The detailed design of the project is
called low level design in that development is done.Unit
and integration testing is perfomed and entry and exit

Answer / smruti
Simply, HLD & LLD's are two levels coming under Test Design
done by s/w testers after completion of BRS & SRS.
High level design defines overall architecture of a s/w is
known as system design or system level document in which
testers are preparing Test Scenarios in MS WORD .
After completion of HLD the testers are preparing LLD's
i.e., writing detailed Test Cases in MS EXCEL which is
based on internal design structure called as module level
document.
