Creating Database Services with Java or C/C++
 
Built-in Database Services
Testing SQL Statements
Error Handling
You can code services that access databases in Java or C/C++. Code your own services if you need a service that performs more complex database operations than a flow service can provide.
To assist you in coding database services, you can use the built-in database services to perform basic database operations and test SQL statements before you add them to your services.
If you want your service to access a database that has nonstandard features (for example, data types that are not supported by SQL), use other database connection APIs. For example, you can make direct calls to JDBC or use other connection libraries, such as ADO.
