All known Subclasses: com.sun.portal.search.db.TaxonomyDb,
| SearchOnlyDb | | public class SearchOnlyDb implements RDMDb(Code) | | SOIF Database API
- handles SOIF db i/o
- provides a template for similar, non-SOIF layers, eg, XML, etc.
- hides db implementation details (eg, db might not contain SOIF)
- hides the mechanics of P/NP data
