Unstructured data is machine or human generated data that does not easily fit into the structure of a database (rows and columns). The bulk of the electronic data we have falls into this category. Oracle Corporation has made significant improvements in performance, security and the types of data you can store natively in Oracle 11g, so you can now more easily store and manage your unstructured data.
There are a number of reasons for storing unstructured data inside of Oracle like:
· Having Robust Administration and Tuning support
· Streamlining Application Development
· Improving Disaster Recovery mechanisms
· Providing Scalability
· Increasing Security
Hugh performance gains in retrieving unstructured files have been obtained by the implementation Oracle SecureFiles. SecureFiles is a new-paradigm for how file data is managing. By using this new technology an application no longer, has to deal with relational data and unstructured file data with two different interfaces. SecureFiles now allows you to have your unstructured data participate in a data transaction. This allows for better backup and recovery of your unstructured data. Also available with SecureFiles is the concept of compression and de-duplication, thus reducing storage cost associated with storing your data.
XML has become a standard for transmitting and storing of data. To leverage XML, Oracle has created Oracle XML DB. Oracle XML DB is a high performance storage and retrieval technology for native XML that supports all key XML formats. In addition to this, Oracle 11g offers some new XML binary storage options and indexing structures for XML data.
There are many additional enhancements in Oracle 11g in how unstructured data types are handled and managed. By using Oracle 11g, you will be able to better manage, secure, query and administer your unstructured data. Additionally you will also be able to improve the performance in retrieving and storing your data, using an open and standard approach.
