I’m reading Fundamentals of Data Engineering: Plan and Build Robust Data Systems, wherein the authors say:

Data is stored in a table of relations (rows), and each relation contains multiple fields (columns); see Figure 5-7. Note that we use the terms column and field interchangeably throughout this book.

There are two mistakes. The first is that tables are relations, rows are tuples. The second is that a field is the intersection of a row and a column, columns and fields are different things.
I have to wonder what business the authors have publishing a book on data engineering while failing to know such basic things.
