Basic introduction
Quartz is similar to most open source frameworks. There are approximately 300 Java classes and interfaces organized into 12 packages. This can be compared to Apache Struts which organizes approximately 325 classes and interfaces into 11 packages. Although size is rarely used as a characteristic to measure the quality of a framework, the key point here is that quartz contains a lot of functionality, and whether these functions and feature sets are, or should be, a factor in judging the quality of an open source or non-open source framework.
Frame features
The Quartz framework has a rich feature set. In fact, Quartz has too many features to appreciate them all in one context. Some interesting features are listed below, but I don't have time to discuss them in detail here.
