A schema is a collection of tables.
A table is a collection of possibly unlimited rows organized into fields or more commonly called columns. Think of a spread sheet.
For example an inventory table might have columns ITEM_NUMBER, ITEM_NAME, and ITEM_QUANTITY.
ITEM_NUMBER is defined to store only whole numbers
ITEM_NAME is defined to store only letters and numbers up to the length of 20
ITEM_QUANTITY is defined to store only whole numbers
Here is some possible sample data
ITEM_NUMBER * ITEM_NAME * ITEM_QUANTITY
1001 * Washer Brass * 5044
1002 * Screw 4x40 stainless * 5027
1003 * Screw 6x40 stainless * 4947
