21. How does OnBase handle document retrieval internally?

Answer:
OnBase retrieves documents using keywords stored in the database.

Process:

  1. User searches using keywords
  2. Query runs on database tables (like ITEMDATA, KEYITEM tables)
  3. Matching document IDs are returned
  4. Physical file is fetched from Disk Group
  5. Document is rendered in client

Performance depends on:

  • DB indexing
  • Keyword design
  • Disk I/O

22. What are the main OnBase database tables you have worked with?

Answer:
Common tables:

  • ITEMDATA → document metadata
  • KEYITEM / KEYTABLE → keyword values

  • USERACCOUNT → user info

Important: Direct DB updates are not recommended unless guided by Hyland.
