This　paper　presents　a　case　study　on　Data-Brain　construction　based　on　Brain　Informatics　(BI)　methodology.　The　Data-Brain　is　a　conceptual　brain　data　model,　which　represents　functional　relationships　among　multiple　human　brain　data　sources,　with　respect　to　all　major　aspects　and　capabilities　of　human　information　processing　system　for　systematic　investigation　and　understanding　of　human　intelligence.　On　one　hand,　developing　such　a　Data-Brain　is　a　core　research　issue　in　BI.　On　the　other　hand,　BI　methodology　supports　such　a　Data-Brain　construction.　A　graphical　modeling　language,　the　View-Fact-Dimension-Model　(VFDM),　is　proposed.　Using　the　VFDM,　we　can　take　part　in　the　Data-Brain　construction　easily,　which　provides　a　long-term,　holistic　vision　to　understand　the　principle　and　mechanisms　of　human　information　processing　system.　©　2008　IEEE.
