You assign each attribute a unique number called an attribute identifier. For

example, you use 1 for list price, 2 for size of lot, 3 for color, etc.

To access the size of lot, you can specify the object by name (House) or by

identifier (1), and the attribute by name (SizeOfLot) or by number (2) in the

format House.SizeOfLot or 1.2.

Now you can list the attributes of House by name and number using the command

list House.

Example

list House

ListPrice = 1

SizeOfLot = 2

Color = 3

Town = 4

Street = 5

House = 6

Garage = 7

Bedrooms = 8

TotalSquareFeet = 9

HowMuchILikeIt = 10

Whenever the number of values of an object is limited, you assign code numbers

to the values. For example, for the Color attribute of the object House, you use

1 for white, 2 for green, 3 for brown, etc.

Until now, we’ve been discussing houses in abstractions, not physical

manifestations. To reference particular houses, you select attributes that, by

themselves, uniquely identify the houses. For example, several houses have a

10,000 square foot lot, but a particular house you have seen is blue. The attribute

Color.TotalSquareFeet identifies the house.

An instance is the MIB name for a collection of attribute values that uniquely

identify particular objects. If more than one blue house has a 10,000 square foot

lot, you need the attributes town, street, and house number (House.Street.Town) to

uniquely identify the house. The instance value 221.Main.Middleton identifies the

house at 221 Main Street in the town of Middleton.

Note:

Do not confuse object or attribute identifiers with values. Identifiers are

numbers you can use in place of attribute names.
