How VDV Works

Vista Data Vision (VDV) consists of three applications. These applications are db.robot.c, db.data.browser and db.web.browser

When we start VDV we always start by running db.robot.c which will also start the MySQL database.

db.robot.c

db.robot.c is a database application, specially made to copy data automatically from .DAT text data files into MySQL database as well as to build all associated tables and to do all book keeping of relations and tags. Also, db.robot.c handles Alarm service, Reports, Validation and other services. 

Db.robot.c utilizes advanced methods for database maintenance, import of modified data and will cope with changing data structure of .DAT files and relocation.

db.robot.c constantly monitors data files retrieved by Data Collection Application and copy all new data into its database without delay. User can give each and every variable a new descriptive name and associate each variable with a unit for calculations and reports.

Also, db.robot.c will allow users to import older data kept in data files and to import modified data in order to add or overwrite data in database with the modified values. Once data is in the database, it can be accessed using db.data.browser and db.web.browser. Experienced users can use SQL commands to read data directly from the database into other applications.

db.data.browser

db.data.browser is a general and flexible data browser, where user can build display pages with up to 6 graphs and incorporate up to 50 variables into each graph. Therefore, a single page can display everything from a single graph with a single variable up to 6 graphs with 50 variables each, or 300 variables total. The graphs can include any variable from any location. Using innovative command buttons, user can easily travel through time and choose any length of period for display.

db.web.browser

db.web.browser is a database web browser, allowing web users to do most of the work handled by db.data.browser through web interface and much more. This application includes everything needed to start web service. Its displays can be configured in any language like English, German and Spanish. Users outside the local network can access the data, as soon as the web server is published to the world wide web. An easy way to start web access to VDV is to use the IIS (Internet Information Server) web server which is built into most of Microsoft's operating systems. Service providers will use the build-in access control to give access to the data, so each user will only have access to the his data and not to data belonging to others.
