Database files created by Berkeley DB can be created in either little- or big-endian formats. The byte order used for the underlying database is specified by calling the DB->set_lorder method. If no order is selected, the native format of the machine on which the database is created will be used.
(디비파일은 little- 또는 big-endian 으로 생성될수 있다.바이트오더는 DB->set_lorder를 호출하여 설정한다.만약 바이트오더가 설정되지 않으면 머신의 네이티브포멧이 사용된다. )
Berkeley DB databases are architecture independent, and any format database can be used on a machine with a different native format. In this case, as each page that is read into or written from the cache must be converted to or from the host format, and databases with non-native formats will incur a performance penalty for the run-time conversion.
It is important to note that the Berkeley DB access methods do no data conversion for application specified data. Key/data pairs written on a little-endian format architecture will be returned to the application exactly as they were written when retrieved on a big-endian format architecture.
