    1. COWhat are the actual transaction errors you are getting in Grails? Are you having real performance problems? Because tomcat-dbcp is based on apache-commons-dbcp, you could see the same problem and you might be better served by switching to something like C3P0 or going with a different application server. [SpringSource tc-Server's DBCP](http://pubs.vmware.com/vfabric52/topic/com.vmware.vfabric.tc-server.2.8/admin/manual-high-concurrency-jdbc.html) "adds additional features to support highly-concurrent environments and multiple core/cpu systems"

    2. COWith SQL Server 2005 you'd have a regular table of records with fields for the address. You'd add columns for the latitude & longitude and then have a batch process that would take each address as input and fill in the lat/longs. This is called "geocoding" and can be done using a web service like Google/Yahoo/GeocoderUS. Then your app code would take an input lat/long & perform the search of the table using Haversine. You are right to question the performance since this sweeps the entire table, but the algorithm isn't complex (in Big-O terms; there isn't recursion or anything).

    3. COI did attempt a few variations of "factory-method" but that does not work here because ThreadPoolExecutor.CallerRunsPolicy is a regular old Java constructor. This is a static class.

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.
