This section describes different design approaches that you can use to extend code in the on-premise and BMC Helix ITSM environments.
- Code reuse
- BMC Remedy AR System platform leverage
- Server and client performance
- Internationalization support
- Business logic objects
- User interface objects
- Message IDs
- Flashboards data
- Reports data
- Naming applications
- Workflow coding style
Avoiding latency issues by using service calls
When you are making customizations, ensure that your changes do not affect the overall response time of clients that are interacting with the system. Any workflow on a client that gathers information should pull that data from the server in the least number of calls possible. If your workflow is designed to make multiple calls from the BMC Remedy Mid Tier to the BMC Remedy AR System server, and back, response time issues might occur due to the latency.
To reduce the number of calls to the BMC Remedy AR System server, you can use BMC Remedy AR System server service calls. In a service call, the active link workflow makes a single call to the BMC Remedy AR System server. That single call causes a form to start a filter workflow that gathers the necessary information and pulls it back to the client.
