How to write the DML commands into PI database?

Hi,

I have one requirement states that the lighting subsystem will have the temperature,luminous etc as a parameters to be stored in PI database as well there can be multiple subsystems also.

For the above requirement, What can be approach to store the parameters under the lighting sub system and manipulate as well as retrieve the data from PI database?

I am using the Java application to connect with the PI database and able to retrieve the data by using PI JDBC.

Is it possible to execute the DML SQL scripts in PI database?

Please help.

Thanks,
