  • Everyone’s talking about big data but the bulk of the conversation seems to focus on a new level of business intelligence and an ever-increasing volume of data organised into OLTP, OLAP and NoSQLsiloes.  In this talk, Mark Wilson puts forward a view that the real value is not from the big data itself but how we can employ linked data concepts to integrate structured, unstructured and semistructured data sets – and then use this unified data source to derive new value.

  • 1. Structuring big data Mark Wilson January 2012#CloudCamp UNCLASSIFIED © Copyright 2012 Fujitsu Services Limited
  • 2. The problem with big data: and a solutionThe problem:  “New reference architectures will include both big data and enterprise data warehouses” [IDC, 19 January 2012]  Two worlds: structured and unstructured data (plus external data sources, documents stored in structured databases, etc.)  Siloes create issues with management, integration, etc.The solution:  Linked data – a single reference point for all data in the enterprise#CloudCamp 1 UNCLASSIFIED
  • 3. Some history Fixed structure  Difficult to change schema Simple reporting capabilities  Complex to create new reports#CloudCamp 2 UNCLASSIFIED
  • 4. Some history Completed transactions transferred to separate database for analysis  “Data warehouse” Better reporting, data mining, etc.  Still highly structured Data is historical  May be aggregated#CloudCamp 3 UNCLASSIFIED
  • 5. The smart guysReal-time update of completed transactions  Transactions moved to data warehouse upon completion  Smaller transactional databaseAllows for alerts to be generated when specific conditions met and action taken#CloudCamp 4 UNCLASSIFIED
  • 6. A third “data silo” Masses of unstructured/semi- structured data being processed in NoSQL databases May, or may not be transferred to/from structured databases  Time-consuming and inefficient Three types of data, each with their own limitations and own management considerations#CloudCamp 5 UNCLASSIFIED
  • 7. Data everywhere!#CloudCamp 6 UNCLASSIFIED
  • 8. Linked DataTie records together – even from separate data setsWe can express as triples with a specific grammar:Build up a graph to show machine-readable data in human form#CloudCamp 7 UNCLASSIFIED
  • 9. Then add lots more data…Source: http://lod-cloud.net/  Each node is itself another graph (zoom in)#CloudCamp 8 UNCLASSIFIED
  • 10. Aren’t we missing a trick?Use linked data as a the optimal reference source  Broker of all data sourcesSingle view on structured and unstructured data  Bring in external sources tooMapping, interconnecting, indexing and feeding  In real timeQuery linked data to derive new value from old  Infer relationships  Gain new insights#CloudCamp 9 UNCLASSIFIED
