3.2. Quick Start Guide

This section is a quick start guide to loading the sample winestore database and understanding the design of the winestore database that is used in examples throughout this book.

3.2.1. Loading the Winestore Database

A local copy of the winestore database is required to test the examples in this and later chapters. MySQL must be installed and configured before the winestore database can be loaded. MySQL installation instructions can be found in Appendix A.

The steps to load the winestore database are as follows:

  1. Download a copy of the winestore database from this book's web site; look for winestore.database.tar.gz.

  2. Uncompress the winestore database package in any directory by running:

    gzip -d winestore.database.tar.gz
  3. Untar the tape archive file by running:

    tar xvf winestore.database.tar

    A list of files extracted is output.

  4. Check that MySQL is running using:

    /usr/local/bin/mysqladmin -uroot -ppassword version

    where password is the root user password. If MySQL isn't running, log in as the Linux root user, and start the MySQL server using:

    /usr/local/bin/safe_mysqld --user=mysql &
  5. Run the MySQL command-line interpreter using the username and password created when MySQL was installed, and load the winestore data. The login name is username, and the password is password:

    /usr/local/bin/mysql -uusername -ppassword < winestore.database
  6. After the loading is complete—it may take a few seconds—the database can be tested by running a query. Type the following command on one line:

    /usr/local/bin/mysql -uusername -ppassword -e 'USE winestore; SELECT * FROM region;'

    This should produce the list of wine regions as output:

    | region_id | region_name         | description | map  |
    |         1 | Goulburn Valley     | NULL        | NULL |
    |         2 | Rutherglen          | NULL        | NULL |
    |         3 | Coonawarra          | NULL        | NULL |
    |         4 | Upper Hunter Valley | NULL        | NULL |
    |         5 | Lower Hunter Valley | NULL        | NULL |
    |         6 | Barossa Valley      | NULL        | NULL |
    |         7 | Riverland           | NULL        | NULL |
    |         8 | Margaret River      | NULL        | NULL |
    |         9 | Swan Valley         | NULL        | NULL |

The winestore database has now been loaded and tested.

3.2.2. The Winestore Database

To complete the introduction to the winestore database, we include in this section a summary of the entity-relationship model of the winestore and the SQL statements that create the winestore using the MySQL DBMS. This section is included for easy reference. Creating the winestore with SQL

The CREATE TABLE SQL statements that build the winestore database are shown for reference in Example 3-1.

The statements in Example 3-1 are derived from the entity-relationship model in Figure 3-1, and the process of converting this model to CREATE TABLE statements is described in Appendix C. An electronic copy of the statements can be found in the winestore.database file used to create the winestore database earlier in this section.

Example 3-1. The complete winestore DDL statements
