CARS DATASET
Version 1.0
September 26, 2007
*****************************************************

The Committee on Statistical Graphics of
the American Statistical Association (ASA)
1983 Cars dataset
available (among other places) from
CMU's StatLib server:

******************************************************
This file describes the contents of the CARS dataset
developed for the CPE 365, Introduction to Databases
course at Cal Poly.
The dataset is a normalized and slightly enhanced version
of the ASA's Committee on Statistical Graphics "cars"
dataset offered in 1983 for the visualization competition.
Please refer to the original dataset description
in the file "cars.desc" included with this distribution for
historical purposes. (please, note, cars.desc file does not
describe the format of this dataset correctly).
The dataset describes the origins and different parameters
of 406 car models produced in the world between 1970 and 1982.
The dataset consists of the following files:
General Conventions.
1. All files in the dataset are CSV (comma-separated values) files.
2. First line of each file provides the names of
columns. Second line may be empty, or may contain
the first row of the data
3. All string values are enclosed in single quotes (')
- car-makers.csv : information about companies that produce cars
- car-names.csv : information about specific cars (by name)
- cars-data.csv : operational parameters of the cars
- continents.csv : list of continents
- countries.csv : list of countries
- model-list.csv : information about car models produced by car makers
The core of the dataset consists of four files: car-makes.csv, model-list.csv,
car-names.csv and cars-data.csv. The first file identifies companies
that produce cars (e.g, "Ford Motor Company", "Toyota"), the second file
lists various models and identified their makes (e.g., "Ford" and "Mercury"
produced by Ford, "Oldsmobile" and "Chevrolet" produced by GM). The third
file is the masterlist of 406 car makes considered in the database
(e.g., "ford torino" or "amc rebel set"). The fourth file contains information
about the operating parameters (see below for a full list) for each make.
Individual files have the following formats.
**************************************************************************
car-makers.csv
Id : unique identifier of the car maker
Maker : short nickname for the car maker
FullName : full name of the car maker
Country : Id of the home country of the maker (see countries.CountryId)
**************************************************************************
car-names.csv
MakeId : unique identifier of the car make
Model : unique name of the car model (see model-list.Model)
MakeDescription : description (name) of the car make
**************************************************************************
cars-data.csv
Id : unique identifier of the car make (see car-names.MakeId)
MPG : milage per gallon
Cylinders : number of cylinders
Edispl : engine displacement volume in cubic inches
Horsepower : power of the engine in horsepowers
Weight : weight of the car in lbs
Accelerate : time to accelerate from 0 to 60mph in seconds (possibly
with fractions of a second)
Year : year the car was made
NOTE: this file adds the Id attribute to the original cars.data file from
the ASA cars dataset, removes the Origin attribute (the origin is
now dealt with elsewhere), and modifies year to be the actual year
rather than "year - 1900".
**************************************************************************
continents.csv
ContId : unique identifier of the continent
Continent : name of the continent
**************************************************************************
countries.csv
CountryId : unique identifier of the country
CountryName : name of the country
Continent : unique identifier of the continent the country is on
(see continents.ContId)
**************************************************************************
model-list.csv
ModelId : unique identifier of the car model
Maker : unique identifier of the car maker (see car-makers.id)
Model : name of the car model (also unique)
