My managing director asking me for these files i dont know why.

check with him u should be clear what exactly he needs.. Is it DDB or ODB++?

Do you mean ODB (well ODB++) format files, if so you create the ODB++ data when you post process the design.
These files are used for PCB manufacture.

hope you are looking for ODB++ data

it is avialable in file--> export -->odb++ inside.

you may need to install odb++ from valor website ( now valor is with mentor graphics!!).

this file is mainly used for DFM checking
