Hi John,
Generally, the VeSys 2.0 database hosted on a server - with all the clients able to connect. The VeSys 2.0 database supports concurrency for users, allowing many users to access the same database (work in the same projects, sharing the same library parts). The only time XML is needed is when you upgrade between major versions (for example VeSys 2.0 v2014.1 to 2015.1), however there is a utility to perform the migration so you would not need to output XML files.
Typical usage of VeSys 2.0 does not require, even with large teams, export/output of XML when making modifications.
Are you evaluating VeSys 2.0, would you be willing to talk? If so then please contact your sales representative and ask for assistance,
Kind Regards,
Nuri
