Talend Data Preparation can use a database as a source for creating datasets. In this Talend Data Preparation for Developers training module, you create a dataset from a MySQL database stored on your virtual machine. Then you create a small preparation for this dataset. This database contains a substantial number of rows. You use some sampling and export features that are available only for large data volumes.
