| 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) | |
