Some integrations may be required to take place in real time, where an action in one system triggers an action in an other system that must take place immediately. These types of integration can be more complex and expensive to implement.

In some cases, near real-time integration is sufficient. Near real-time integration is still quick but processing may be measured in minutes rather than seconds. If there is no requirement for such a quick action, batch integration may make the most sense. In contrast with real-time or near real-time integration, ...
