6. Technical Challenge

7. Technical Challenge Continued  Storage  Search – Across all content types – Including calculations on the fly  Retrieval – For Presentation – XML  Allow easy addition of new content  Abstract data model away from applications/Business Services  Large number of items stored – 3-5 million companies (growing to 20)  Hundreds to thousands of attributes on each – 12 million executives (growing to 30) – 20-40 million documents

8. Solution  Metadata Driven Database  Combine Relational Database with XML  Create Abstraction for Queries based on XPath  Oracle Backend with.NET Applications

9. Metadata Driven  Two levels – Data dictionary about content – Metadata associated with content  Why important? – Allows new content to be added easily – Allows search and retrieval of metadata  Date of change, units, source, attribute definition

Example of Conceptual Model Larry EllisonOracle Peoplesoft E-Travel, Inc Apple Redwood City, CA Corporate Family: Past Subsidiary Location: Headquarters Event: Tender Offer, $7.3 billion Expiries Sept. 17th Employee: CEO Employee: Former Board Member Left September 2002 Employee: Board Member Arthur LevinsonGenentech Event: Sold, 2001, to Amadeus Global Travel Employee: Board Member

12. Data Model Overview Entity AttributeValueSource Instance Attribute Source Information

13. Combining Data Types  Many Value Tables – Number, Money, Date, String – Text/Document, XML, XBRL  Query Examples – Find Companies where sales > $1B and company description contains “Software” – Find Companies with 25% annual sales growth over the last year and has a news story that contains “Footing” near “Cement”.  SQL Queries become complex

14. Query Abstraction  Virtual XML document representing all content  Use XPath style query syntax abstraction above SQL  Transform XPath Syntax into PL/SQL  Examples: – Company[Employees > 10000 and Country/ISO2 = ‘US’] – Company[os:contains(BusinessDescription, ‘near(software,application))’ and AreaCode= ‘508’ and Sales[@currency = ‘USD’] > 10000000 ] – Company[Parent/State = ‘MA’ and Sale[@currency = ‘USD’] > 10000000]

15. Oracle and.NET . NET front end using ODP.NET – Flexibility where we process (database, business service, UI) – ODP.NET is full featured and performs well – Oracle has full support of.NET  Common business service layer  Allows multiple front-ends – Web subscription – SDK – Modules for third-party applications

16. What this Solution Enables  Complex queries across all content types – Example: “Find all companies where there has been new CFO, and revenue per employee greater than $500k, with ultimate parent in CA”  Storage of XML content natively (XBRL, NewsML) – Detailed financial data integrated into 3 rd party applications via Web services  Faster integration of new content  Rapid deployment of new products
