SecureFiles

Structured data: Tables/columns according to businessrules

Semi-structured data: XML, PDF etc

Unstructured data: Images, audio, video streams etc

Multiple data stores in IT datacenters

Relational databases – Structured Data

File systems – Semi-Structured and Unstructured data

Simplicity and performance of file systems makes itattractive to store file data in file systems, while keeping relational data inDB

Enterprise applications manipulate both files and relationaldata

e.g. Document Management, Medical, CAD, Imaging

Disjoint security and auditing models

Changes cannot be made atomically

Backup and recovery are fragmented

Search across relational data and files is difficult

Space management is complicated

Separate interfaces and protocols

LOBs in the database are stored inside database tablespacesin a way that optimizes space and provides efficient access.
