Vista Control Systems ®
has implemented several
open interfaces and scanners. We are also implemented several new open
interfaces:
-
ODBC
-
JDBC
-
Java server
-
World Wide Web
-
OPC
-
Programming API
ODBC - Connect to office applications
Generic database management systems
(DBMSs)--such as
MS Access, Excel, Visual Basic Apps, etc.--that use ODBC (open database
connectivity) will connect to and query Vsystem databases and eventually Vlogger
data.
The ODBC interface allows an application to access data
from diverse DBMSs through a single interface, while remaining independent of
these DBMSs.
You can use DBMSs to read live data from
Vsystem databases on-line and Vlogger files. And, as always with Vsystem, the databases are not
limited by platform.
JDBC - Incorporate Java Applications
JDBC can be used through the ODBC
interface. Java contains a JDBC-ODBC interface allowing for Java
programs to access Vlogger files and Vaccess database.
Java server - Incorporate Java
Applications
Java is an object-oriented language that requires a new
interface to Vaccess and Vlog files. Our Java interface will provide this, using an
efficient Vsystem Java interface. As a result, users will be able to choose to implement
their application code in Java. This Java interface will also be used to support
our Vdraw/web connection (see below).
World Wide Web
Vsystem will have the ability to display Vdraw
.vcd
(vista control display) files on the World Wide Web via Java. Users will be able
to create and edit a .vcd file with the standard Vdraw program and then
display it in active mode, either with Vdraw, using the native operating system
graphics, or through a web browser.
Applications that use browsers to display data over the
network allow almost any computer to access the system and see the data. Of
course, the implementation can use file security and Vsystem security to
restrict access to this data.
OPC
The Vsystem OPC server (as
opposed to the OPC Scanner which is a client) provides other software packages
access to Vsystem current data and will also accept set-points from the other
package.
Programming API
The full API for Vsystem is
documented and available in the standard package. In addition, the API's
and Vsystem channels (tags) can be used to control the behavior of Vsystem
components giving market-leading flexibility to implementers of applications.
