Isnt it very obvious 10.2.0.3.0 is the version?

Each component may have different version numbers (otherwise, why have seperate lines?), but the database itself, the main component, will be the CORE line.

If you're asking about the numbers; according to Wikipedia:

The version-numbering syntax within each release follows the pattern: major.maintenance.application-server.component-specific.platform-specific.
