+ * TDbLogRoute class
+ *
+ * TDbLogRoute stores log messages in a database table.
+ * To specify the database table, set {@link setConnectionID ConnectionID} to be
+ * the ID of a {@link TDataSourceConfig} module and {@link setLogTableName LogTableName}.
+ * If they are not setting, an SQLite3 database named 'sqlite3.log' will be created and used
+ * under the runtime directory.
+ *
+ * By default, the database table name is 'pradolog'. It has the following structure:
+ * <code>
+ * CREATE TABLE pradolog
+ * (
+ * log_id INTEGER NOT NULL PRIMARY KEY,
+ * level INTEGER,
+ * category VARCHAR(128),
+ * logtime VARCHAR(20),
+ * message VARCHAR(255)
+ * );
