viva 1.1
1.5 Database
Introduction
viva is based on an object-oriented database that has proven itself in
practice. All program settings, user administration, methods and templates
are stored in the configuration database, and the determination data is
stored in the determination databases defined by the user. These data-
bases can be installed locally on the computer reserved for measurements
and represent a simple measurement system. viva is, however, scalable
and grows with increasing operational requirements. As soon as data
security and central data management make it necessary, viva is installed
as a client/server configuration. The viva database is then installed on
a server. All measurement and office computers work as clients. All results
are stored centrally in this network and can be accessed and reprocessed
by all client PCs. In addition, all clients use the same method pool.
The new database has all the major tools necessary for managing, search-
ing for and grouping results. Quick filters allow the user to browse
through thousands of determinations within seconds and to display the
result clearly. Chart plots provide a quick overview of the chronological
sequence of the results.
All options for reprocessing are available to the user.
