Insert Information Protection Policy Classification from Slide SecureFiles Performance & Scalability on Exadata  Small Documents: Extremely High Throughput – Load at 200 Million docs/hr, Read at 780 Million docs/hr  Large Multimedia: Extremely High Bandwidth – Load at 4 GB/s and Read at 8 GB/s

Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide Oracle Database DBFS  DBFS – Database File System – Make Oracle Database behave like a file server – Access to files inside the database is now same as file system access – Performance and scalability: 1 billion file test

Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide Database-Enabling File-Based Tools  DBFS allows access to files in the db using file system interfaces – File operations translated into SQL operations – Directories and path names are derived from key columns in tables – Enables access by existing file-based tools /Customers /Lucas /…….. /Contract /Photo Path Names, Directories DBFS Server in DB Select Contract from Customers where Name = ‘Lucas’ Acrobat Reader ID#NameAddressContractPhoto 23Lucas …..

Insert Information Protection Policy Classification from Slide Oracle DBFS HSM  DBFS Hierarchical Storage Management – Transparently migrate a SecureFiles LOB to tape or cloud – Replace the LOB in the database with a DBFS Link – DBFS Link looks like the LOB to applications and users  Slower “time to first byte”

Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide DBFS HSM Store  A DBFS HSM store allows archiving files to tape  Application migrates older files to HSM store (e.g. old invoices) – A DBFS Link replaces the LOB, LOB reads on links are transparent – A LOB can be easily migrated back to the table for updates  HSM store: disk staging area for storing recently accessed files – Seldom accessed files are migrated to tape, brought back on reference Order#CustomerYearInvoice 1234Lucas2003 Sales Table /HSM /Old_Invoices /…….. /Invoice_1234 “/HSM/Old_Invoices/Invoice_1234” DBFS Link LRU Tape

Insert Information Protection Policy Classification from Slide Oracle Database Flashback Data Archive & CQN  Flashback Data Archive – FDA – Transparently store history of changes – Automatically delete data that is older than specified retention period – Works with structured AND unstructured – SecureFiles – data – Beginnings of integrated transparent provenance  CQN – Continuous Query Notification – Register SQL – actually CQL – queries in database – Each registration includes notification method / code – Fully contextual event processing – Combine with FDA and SecureFiles

Insert Information Protection Policy Classification from Slide Build your own “file system”  Similar to how databases allow you to create a data model & an application, you can now build your own file system – Innovate and create new value by creating a file system interface  Database developers can now write a robust file system: No need to be a OS kernel developer or debug kernel crashes  Create a file system interface to data stored in relational tables: Like a “file system view” for an existing database application  Write a file system in Java, SQL/PL/SQL – Or any other language using callouts  Build your application-integrated file system in less than a day – Writing a basic read only file system view on the LOBs that are currently in your database application in 60 seconds!

Insert Information Protection Policy Classification from Slide Files in the Database Reinvented File Capabilities – File System Interface – High Performance – Compression – Encryption – Deduplication – HSM Database Capabilities – Transactions – Query Consistency – Advanced Backup and Recovery – Powerful Security – Flashback – Scale up and out  Files are an integral part of modern database applications – Product images, contracts, XML, ETL files, manuals, etc.  Applications developers want to store business data files in the database to benefit from transactional consistency, and unify HA and Security – Poor performance, limited functionality, and lack of access by existing file based tools have held them back  Oracle Database 11g reinvents files in the database  SecureFiles provides super fast and powerful file storage – Removes performance barrier to storing files in the database  DBFS provides a file system interface to files in the DB – Enables existing file based tools to easily access DB files

Copyright © 2013, Oracle and/or its affiliates. All rights reserved. Insert Information Protection Policy Classification from Slide Oracle Database and Information Retention  Keep metadata and files together in Oracle Database – Unified backups – Unified security model – ILM and HSM – Leverage other database features  Application developer agility – Much less work to implement content management applications – Just like SQL and RDBMS’s, reduces the amount of “wheel reinvention”
