Integration Testing: As modules are developed they get integrated as part of design. Then individual and net behaviors need to be tested. This type of testing is known as integration testing.

System Testing: When an application is deployed into environment it becomes system. Testing performed on this type of setup is called System testing.

System Testing:In system testing we test the system works well in the real environment with the real data. Since the servers and data are different it may not work as expected.

Integration testing:In integration testing we make sure that all the components in the application are integrated together or not and work well as per the requirement document.
