Database Tables
    Database tables are used in situations where you need to store an unknown number of items for a company, contact and so on.

For example, in a database of students you might use a database table to store which exams each student has taken and what grade they got.

The list will be different for each student because they all take different courses, so using the user-defined fields would be complicated, however using a database table you could set columns for Course, Grade and Year taken and simply add a new row to the table for each exam result achieved.

Database tables have a maximum of 5 columns but a virtually finite number of rows. You can hide unused columns if you wish. There are 5 database tables for each type of entry; Company, Contact, Family and Asset.
     
    Column totals
    If one of your columns holds numerical data you can display a total at the bottom of the table by setting the Last row content property of the column to Sum of this column.

You can also choose to display the average, highest and lowest value.
