Assume Acme has four types of classifications for its software bugs: (1) nasty, (2) cosmetic, (3) fluff and (4) documentation. The goal of this exercise is to plot the number of bugs reported over time for each of the four classifications.
For this scenario, assume Acme's database was created with the schema shown in figure 8.1(intentionally kept simple for illustrating graphs).
NumberOfDaysSinceLaunch type integer
CumulativeNumberOfBugs type integer
Figure 8.1: Acme's bug tracking schema
The attributes for Acme's schema are described below:
Also, assume the contents of Acme's bug tracking database contains the records displayed in table 8.1.
