Summary

This chapter covered a whirlwind of fundamental topics that we will need in order to clean data in the rest of this book. Some of the techniques we learned here were simple, and some were exotic. We learned about file formats, compression, data types, and character encodings at both the file level and database level. In the next chapter, we will tackle two more workhorses of clean data: the spreadsheet and the text editor.
