We started with exploring the different data formats supported by ML Studio. Then we explored how to import data from external sources and how to export a dataset to external sources. We used the Reader module to import and the Writer module to export data. You also learned about the Enter Data module, which lets you build a small dataset by entering data manually.

After you import data from a source to ML Studio, it often needs some kind of preparation before you apply machine learning algorithms to it. Also, certain machine learning algorithms require certain preprocessing of the data. In the next chapter, we will explore the different data preparation options available with ML Studio.
