Although this format is documented, it should be treated as an impenetrable black box in most circumstances. Howver, the file format is identical on all platforms that run SQLite version 3. You can, for example, take any SQLite database that was created on an iPhone, and read it on a Windows computer, or vice versa. There are some minor format differences between different versions of SQLite. For instance, if you use the ALTER TABLE ADD COLUMN command introduced in 3.2.0, versions before that will not be able to read the file. However, changes like these are very rare (it's happen just twice and we're up to 3.7 now) and if you keep to relatively similar version numbers on your two platforms you're unlikely to have problems.
