Types of loads in informatica

Full Load

The data is loaded to the Warehouse for the first time.

Incremental Load

Next time onwards incremental load is done. The data is appended to the historical data.

We generally do this type of load.

Refresh Load

Suppose the data loaded is full of errors, entire data is reloaded. In this case only we need the Truncate Target Table Option. Rarely used.
