Here are the columns, types, and some other info if needed: STNO (INTEGER) - this row uniquely identifies each student! SNAME (TEXT) MAJOR (TEXT) - this row only holds values that are a valid Dcode from the Department_to_major table CLASS (TEXT)
We need tо use the SQL DDL in аn SQLite dаtаbase tо set up a database tо keep information about students taking courses and their majors.

Here are the columns, types, and some other info if needed. This is a little bit of a weird table with only two columns, but it exists to "convert" a short department code (like INFO-C) to a longer one (like "Collaborative online informatics").
