-- Table structure for table `notification`

CREATE TABLE `notification` (
  `pk_id` int(250) NOT NULL,
  `fk_uid` int(250) DEFAULT NULL,
  `status` enum('1','2','3') NOT NULL DEFAULT '1' COMMENT '1-pending,2-accept,3-decline',
  `title` text COMMENT 'message notification',
  `created_date` datetime NOT NULL COMMENT 'created date and time',
  `updated_date` datetime NOT NULL COMMENT 'updated date and time',
  `read_status` enum('1','2') NOT NULL DEFAULT '2' COMMENT '1-read message,2-unread message',
  `ip_address` varchar(250) DEFAULT NULL COMMENT 'ip address'
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

-- Indexes for dumped tables

--
-- Indexes for table `notification`
--
ALTER TABLE `notification`
  ADD PRIMARY KEY (`pk_id`);

--
-- AUTO_INCREMENT for dumped tables
--

--
-- AUTO_INCREMENT for table `notification`
--
ALTER TABLE `notification`
  MODIFY `pk_id` int(250) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=2;

above notification table required read,unread status because particular user notification you fetch at that time know that this particular user notification is read or not, when notification read then change status of notification table
ip address is filed store ip address of created notification its generally used for notify information,
