Body
In my project I have written the DAO-s and I want to use a scheduler that will call a DAO.delete() method every week for some of the tables of my mysql database. And in case any exceptions is caught and when the task has finished I want log4j to have stored in a table called logs, every possible log of events that occurr related to data through the DAOs... I have implemented a connection pool ... how do other threads of the cron4j scheduler and log4j scheduler affect (if they do) the concurrency of the connections of the database? ... Please feel free to advice as much as you can with this problem ... many thanks in advice ...

Guidance

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.
