Answer 1

Isnt it very obvious 10.2.0.3.0 is the version?

Answer 2

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.
