> * Check for proper javadoc
> * Remove unnecessary logging, adjust log level properly
> * Consistent transaction handling:
> ** No rollback for selects
> ** Exception in case of update count mismatch (single row update returns 0
> or >1 for updated rows)
> ** Review proper usage of RetrySemantics.* annotations
> * Common private template methods for 'infrastructure' code (same try-catch
> logic, connection handling, etc: possibly with spring-jdbc
> * Replace inline hardcoded and assembled SQL statements with parameterized
> constants.
