The Internet of Things (IoT) is the dynamic and global network infrastructure where smart interconnected objects continuously generate massive amount of data which then transmitted over internet. A lot of work is done on building low cost small devices, their connectivity and communication. However there is a little work done on data management as well as the type of database systems (DoT: Database for IoT) that must be used in IoT. DoT requirements are different than the traditional database requirements. WSN Data management solutions are applied to Iot but WSN is just a part of IoT and it needs another solution for data management. In this paper we will focus on different types of IoT data, data management and their challenges in IoT . This paper also considers database requirements for IoT and focuses on selection of DoT by considering type of devices and their capabilities.

Water is essential for life as well as for the economy. Nowadays, to solve and manage the water scarcity is becoming challenging. With the reduction of water resources, the demand for quality water is increasing day by day. Water utilities are important to provide good quality water, but due to outdated or lack of sufficient infrastructure it becomes difficult. Along with this, water get wasted due to metering errors, leaks, pipe bursts, and becomes polluted because of industrial waste. To manage all these issues, water utilities have to come up with smart water management solutions and techniques. This paper proposes a mechanism that predicts the amount of water that can be made available for consumption, distribution, storage of Agriculture, Domestic, Industrial purposes. This mechanism takes into consideration four important factors -current population, current water levels from water reserves, amount of rainfall, amount of water currently consumed. By this mechanism, it will be possible to make predictions as to, how much water should be made available based on the available statistics. KeywordsIoT, ,smart water management, water problem.
