2.3. Standing Stones and the Sample DatabaseOur small example databases throughout this chapter will contain information on megalithic sites within the UK. A more complex version of this database is used in the following chapters. The main pieces of information that we wish to store about megaliths[7] are the name of the site, the location of the site within the UK, a unique map reference for the site, the type of megalithic setting the site is (e.g., a stone circle or standing stone), and a description of what the site looks like.
For example, we might wish to store the following information about Stonehenge in our database:
With this simple database, we can retrieve all sorts of different pieces of information, such as, ``tell me of all the megalithic sites in Wiltshire,'' or ``tell me about all the standing stones in Orkney,'' and so on. Now let's discuss the simplest form of database that you might wish to use: the flat-file database. Copyright © 2001 O'Reilly & Associates. All rights reserved. |
