 * The DynamoConnection class is a wrapper interface to the NetImpact Dynamo query.

 * Lifetime: created when the servlet starts.
 * Becomes garbage when the servlet exits.
 *
 * See SQL Anywhere documentation on NetImpact Dynamo for a description
 * of the methods, but be aware that, in Java, the first character
 * of a method name is always in lower case.
