The present invention relates to a method for preventing the simultaneous modification of the same database object in a shared database by more than one user during the database development stage comprising the steps of: (a) creating security roles for said users, wherein each of the security roles has a modification permission set for denying or granting at least one modification permission to at least one said database object; (b) assigning each of said security roles to each of said users; (c) providing means for said users to request said modification permission to said database object; (d) receiving said request from a first user for said modification permission to said at least one database object; (e) determining that said security roles of said users, excluding the security role of first user, are set to deny said modification permissions to said object; (f) updating said security role of said first user to grant said modification permission to said object; (g) allowing said first user to modify said object; (h) receiving a termination notification from said first user for concluding said modification permission to said object; and (i) updating said security role of said first user to cease said modification permission to said object.
