David J Parker's background has been in data visualization ever since he struggled to produce lists of hospital equipment from Computer Aided Design models of buildings as a budding architect in the '80s. He moved into building and infrastructure asset management in the late '80s using a Unix system and gradually migrated to Windows-based systems throughout the '90s.

David started bVisual Ltd. in 1998, which provides Visio-based solutions to various industries, and became a Silver-level Microsoft partner.

He has been a Microsoft MVP (Visio) for the last 12 years and has helped Microsoft Corp, UK and Western Europe, by providing Visio solutions, training, website content, and presentations. David has had several books on Visio published and has been presenting Visio/SharePoint integration courses for many years for Microsoft Western Europe, from Oslo in the North down to Lisbon in the South.
