    1. COA couple of questions you could ask your self and add as edit to your question. What is your thought for and against making it transient? What does transient mean?

    2. COI should have mentioned, I like the idea of having a logger for each instance rather than one for each class. I would have many instances of the same class instantiated and managed by a container (say a Spring application context) and would like to switch logging levels on a per-bean basis rather than on a per-class basis. In the example of a Spring application context, the logger would be declared as something like private final transient Logger log = Logger.getLogger(getBeanName()); where the bean is no longer a POJO and implements BeanNameAware

    3. COSee also [the SLF4J FAQ](http://www.slf4j.org/faq.html#declared_static): *"Should Logger members of a class be declared as static? [...] In summary, declaring logger members as static variables requires less CPU time and have a slightly smaller memory footprint. [...] However, instance variables make it possible to create a distinct logger environment for each application, even for loggers declared in shared libraries. Perhaps more important than previously mentioned considerations, instance variables are IOC-friendly whereas static variables are not."*

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
