Linking Multiple Data Sources
• Avoid duplication of data between systems
– Multiple update problem
• Embedding references (URLs or equivalents)
• Example - Visio hyperlinks to
– Other Visio diagrams
– Excel/Word
– URLs

• N.B. the answer is not…
Challenges
• Data vs Information
– Linking data sources
– Standardisation of output formats
• Clarity of data ownership
• Organisational structures
• Project vs Operational Documents
– Business as usual vs Investing for the future
• Tooling support
