according to software market "Build Management " is tht kind
of management which manages varios builds of software. and
"release management" which manages release of software.


ex-suppose in company there is project assigned to
developers and testers ,developers do coding after code
generation , testers do testing of tht appliaction ,so many
bugs found. then they  will tell to developers to fix it.
developers fixed tht now "build 2 "  is released  with fixed
issues thatwas found by testers , now again testers do
regression testing,again found bugs, again same
proceduregoes on  but now "build 3 " has been released to
testers . but here the issues are 2% and stable . then they
finally "release1" has been released in market or in tht
company or clients.

we can say tht in release managemnet , build managemnt comes.


hope u got the answers
