RTD DB Add-Ins

The add-ins preprocess data before sending it to a database. The add-ins can be implemented in C++, C#, VB.NET, or other languages. This feature supports various use cases, including data broadcasting.

The add-in must implement the IRDDataProcessor interface defined in IDataProcessor.dll:

void IRDDataProcessor.AppStart()
void IRDDataProcessor.AppStop()
bool IRDDataProcessor.ProcessRow(IRDDataRow data)

RTD DB invokes the ProcessRow method prior to saving data to the database.

The IRDDataRow contains the following members:

string ServerName { get; }
string DatabaseName { get; }
string Table { get; }
string ProgID { get; }
object Item(string columnName) { get; set; }

The add-in can read and modify the column data of the current row using the Item property.

To attach the data processor add-in, update the configuration file as follows:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="DataProcessor" value="RTDataBroadcastProcessor.dll"/>
  </appSettings>
</configuration>

In the downloaded package, find examples of add-ins implemented in C# and VB within the DataProcessor.zip file.
