question about converting from java

[cutekittenkyti]

I'm considering Labview to build a GUI for a project.

This project needs to have as few time delays as possible.

The project has a GUI that selects a circuit breaker from a list. Then using SCADA it accesses the data. Our program uses oracle database and a PI server to get the data. The minimum time to receive the data is about two seconds. Which considering that the program is supposed to display the data in real time is a problem. However our program can get away with approximating the real time data, but time delay is a concern.

so in our program we are converting the data from the SQL language into  java. Java has a feature to acess SQL. Then my teamates, once they have the data, send it to me to put it into a GUI.

Now if I make a GUI in java, there won't be another time delay in converting the code. But I know almost nothing about java, and a decent amount about Labview. So building the GUI in labview is an option.

But the main problem/concern is, does getting the data/code from java take a decent amount of time. And how much time are we talking about exactly. Can anyone give me an estimate.

My teamates java program will be sending me two voltages, a slip frequency, phase angle, and a direction

Also can labview send data to java (time isn't a big deal on this part)

You could have the Java program write the data to file, have the LabVIEW program poll for a change to the data file and then read in the changes and update the GUI appropriately.  You could reverse the process to have LabVIEW data sent to the Java program.

So does LabVIEW. You can either use the Database Connectivity Toolkit or use the free LabSQL. If that's all you're using Java for, then I would look into using either of the aforementioned to get the data directly into LabVIEW.
