System Integration means testing the application as a whole.

In general application will be developed in modules, and all these modules will be integrated to yield the final app....

testing this entire app is system testing....

It is black box testing

Example:

If there are two modules in a system like BILLING (with 20 programs)and INVOICE (20 programs).

Because of a business requirement Dev team has changed 4 programs in the Billing module and need to test. 

Unit Testing: Testing each and every changed program separately.

Integration Testing: Testing BILLING module as a whole (both changed and unchanged programs) .

System Testing: Testing entire system as a whole (both BILLING and INVOICE).

System Integration Testing: Testing entire system as a whole (both BILLING and INVOICE) and at the same time Database should be checked for data validation. In case of system test we may/may not check whether data is getting passed correctly or not. But in case of SIT, we have to check the data also.
