... 03.500 82 Chapter 1 Fundamentals You will notice at listing lines 53 through 57 that I chose to add some more records. I just wanted to make things painfully obvious during the rest of the test. There is nothing really magic about the values in those records, other than the fact they are easy to spot. Pay special attention to listing line 82. Do you remember what I said earlier? I deliberately left this line where it was to prove that statement. Now, let's take a look at the output. roland@logikaldesktop:~/fuelsurcharge2$ javac doeHistory .java roland@logikaldesktop:~/fuelsurcharge2$ javac testpackDoeHistory .java roland@logikaldesktop:~/fuelsurcharge2$ java testpackDoeHistory ... those records, then attempt to add three records which have the same primary key value.

... Inc. really needs to get into this personal file server market. There are probably still a lot of tools out there which support Btrieve and let end users create things by picking and pointing. Memory and bandwidth issues simply cannot be overlooked when designing an application. I provided only a few hundred records for our test database and I'm creating the files locally. What happens when you modify this application to open a DBF and NDX which are on a Web site or remote file server? Unless you are on dialup, you probably have enough bandwidth to transfer fewer than 400 records. How about when the file is approaching 2GB and the end user is on a satellite connection with a 120MB per day bandwidth restriction? ... is a resourceintensive pig that imposes severe data access restrictions by requiring either exclusive access to the entire data set, or a live data monitor communicating with the database to monitor for any and all record changes. 102 Chapter 2 – MegaZillionaire Application 2.2 2.22.2 2.22.2 2.2 Supporting Classes Supporting ClassesSupporting Classes Supporting ClassesSupporting Classes Supporting Classes MegaDBF .java 1) package com.logikal.megazillxBaseJ; 2) 3) import java. io.*; 4) import java. util.*; 5) import org.xBaseJ.*; 6) import org.xBaseJ.fields.*; 7) ... intervening database engine locking all files and providing all access.
