 SecureFiles -
The Next Generation Unstructured Data Management
SecureFiles is a
new feature in Oracle Database 11g that offers
best solution for storing file content such as images, audio, video,
PDFs, spreadsheets etc. Traditionally, relational data is stored in a
database while unstructured data is stored as files in file systems.
SecureFiles is a major
paradigm shift with the
choice of files
storage. SecureFiles is specifically engineered to deliver high
performance for file data comparable to that of traditional file
systems while retaining the advantages of the Oracle database.
SecureFiles offers the best-of-both-worlds
architecture from both the database and filesystem worlds for storing
unstructured data.
SecureFiles is a completely new architecture inside the Oracle Database
11g for handling file or unstructured data. It
features entirely new disk formats, network protocol, space management,
redo and undo formats, buffer caching, and intelligent I/O subsystem.
SecureFiles represents the core infrastructure for managing
unstructured content inside the Oracle database. With SecureFiles,
Oracle has perfected the use of the database for storage of all
enterprise data.
Key Technical
Advantages
SecureFiles
is designed for high performance and includes advanced features
typically found in high-end file systems.
 In
addition to these advanced file system features, SecureFiles can
take advantage of several advanced Oracle Database capabilities such
as:
- Transactions, Read Consistency, Flashback
- 100% Backward Compatibility with LOB
Interfaces
- Readable Standby, Consistent Backup,
Point in Time Recovery
- Fine Grained Auditing, Label Security
- XML indexing, XML Queries, XPath
- Real Application Clusters
- Automatic Storage Management
- Partitioning and ILM
Data stored in SecureFiles can be accessed through both database and
file system clients. SecureFiles interfaces are completely backward
with LOB interfaces. More information on using SecureFiles and
Migration can be found here.
