Data Archival = Data Survival

by Ali Elkortobi


Data needs to survive technological evolutions because data may still be needed many years after its creation and active usage. Structured data is particularly challenging since it must be stored in a format that survives:
• Database evolutions and migrations
• Application versions and migrations
• Operating system evolutions and migrations
• CPU/Storage evolutions & migrations


We believe that XML is a great format for storing long-term, survivable data. XML has the advantage of being pure text, where data and its metadata (description of the data) are kept together. XML has become a widely used format adopted by many open source programs and utilities.


Furthermore:
• XML is searchable via XQuery and/or text retrieval. Because we are storing structured data as XML, it can be also queried thru SQL
• XML is verbose, but can be compressed by significant ratios. Ideally, queries should be possible on compressed XML


HP Database Archiving software fully complies with our proposal for the data life cycle and enables SQL queries on compressed XML. All you need is the data and an enterprise reporting tool. Encapsulating complex business objects data inside one XML file, opens an opportunity to apply record management to structured data as well as unstructured data. These XML files can be managed by a specialized record management tool such as HP TRIM.


Long live your data.
