In fact, most programming is founded by discrete math so I would highly recommend understanding this field of mathematics if you are new.

  2. What is a column?
    A column represent a specific kind of data. Rows are first described as a data type (Alpha Numeric, Number, etc) and size (1 character, 4000 characters, etc). The data stored in a column will all be similar. For example the first column is for names.

  3. What is a table?
    A table contains a specific group of information. A table could represent the information about a group of people. IE the names, height, hair color, eye color, for all of the people with a state drivers license. A table is made up with rows and columns, similar to a spreadsheet or a ledger.
