usage...sed/awk/reg-exp ..in shell scripting

in shell scripting there is extensive usage of

i> regular expression
ii>sed
iii>awk

can anyone tell me the suitable contexts ...i mean which one is suitable for what kind of operation.

like the reg-exp and sed seems to be doing the same job..i.e pattern matching
