David J. Parker, being frustrated as an architect in the late 80s trying to match 3D building models with spreadsheets, explored linking Unix, CAD, and SQL databases in the early 90s for facilities and cable management.
In 1996 he discovered the ease of linking data to Visio diagrams of personnel and office layouts. He immediately became one of the first Visio business partners in Europe, and was soon invited to present his applications at worldwide Visio conferences. He started his own Visio-based consultancy and development business, bVisual ltd (http://www.bvisual.net), applying analysis, synthesis, and design to various graphical information solutions.
He presents Visio solution providers and Visio Services courses for Microsoft EMEA, adding personal anecdotes and previous mistakes hoping that all can learn by them.
He wrote his first book, Visualizing Information with Microsoft Office Visio 2007, to spread the word about data-linked diagrams in business, and his second book, which is about creating custom rules for validating structured diagrams in Visio 2010, has now been updated and extended for Visio 2013.
He wrote WBS Modeler for Microsoft, which integrates Visio and, Project, and many other Visio solutions for various vertical markets.
David has been regularly awarded Most Valued Professional status for his Visio community work over the years, and maintains a Visio blog at http://blog.bvisual.net.
Based near to Microsoft UK in Reading, he still sees the need for Visio evangelism throughout the business and development community, and has been touring many European capitals over the last two years spreading the word of intelligent business diagramming with Visio and SharePoint.
