So far all the data we've been migrating has come from a MySQL database but Migrate supports a number of other data sources which we can access by using a different source migration class. In this lesson we'll look at the source migration classes that are available with the migrate module and talk about what each one could be used for. Then we'll implement a migration that imports data from a CSV file since that's another common way of receiving source data.

For your convenience, we've included a copy of the sample data in the companion files. This is a duplicate of the data from lesson Set Up Migrate Demo Site and Source Data. If you've been following the lessons in order, you should not need to download the sample data set again.
