The International Data Corporation (IDC) surveys and indicates that the big data market will reach over US$155 billion by 2020 . IoT bigdata analytics is defined as the various steps examined to reveal unseen pattern ,hidden correlation and new information. Companies and individuals has getting benefit from analyzing large amounts of data and managing huge amounts of information that can affect on businesses .The aim of big data analytics to achieve improved understanding of data ,make efficient and well informed decisions for the benefits. Moreover, big data analytics aims to extract knowledgeable information using data mining techniques that help in making predictions, identifying recent trends, finding hidden information, and making decisions . The Techniques which are used in data mining are widely deployed for both methods problem-specific methods and generalized data analytics. IoT data are totally different from normal big data collected through systems in terms of characteristics because of the various sensors and objects involved during data collection, which include heterogeneity, noise, variety, and rapid growth. Data analytics and IoT into big data requires huge resources, and IoT has the capability to fulfil it. Application areas, such as smart ecological environments, smart traffic, smart grids, intelligent buildings, and logistic intelligent management, can benefit from the aforementioned arrangement.

2. The IoT
Internet of Things( IoT) is a network in which real objects such as devices ,buildings and vehicles are embedded with a software, sensors and has network connectivity in which objects communicate with each other. IoT(internet of things ) allows objects to be controlled remotely and sensed across the network in which it is present. Data collected through the sensors can improve our lives and help to build an intelligent society. It also creates an opportunity for direct integration with the computer based systems which helps in improving the result accuracy and also helping our economic benefits. IoT(internet of things ) offers a platform on which sensors and devices can share data information in a convenient manner. In the recent years different wireless companies places IoT(internet of things) as an next emerging technology. IoT(internet of things ) is recently used for making a smart office, smart retail, smart agriculture, smart water, smart transportation, smart healthcare, and smart energy. During survey experts say that IoT(internet of things) will consist have about 56 billion objects by 2025. Cisco and Qualcomm have using the term 'Internet of Everything' (loE). However, Qualcomm's use of the term has been replaced by the 'Internet of Things' (loT) by others. Over 50 billion devices e.g. Smartphone’s, laptops, sensors, and game consoles are anticipated to be connected to the Internet through several heterogeneous access networks enabled by technologies, such as radio frequency identification (RFID) and wireless sensor networks.  mentioned that IoT could be recognized in three paradigms: Internet-oriented, sensors, and knowledge . The recent adaptation of different wireless technologies places IoT as the next revolutionary technology by benefiting from the full opportunities offered by Internet technology.

3. BIG DATA
The huge amount of data generated by temperature sensors, sensors, devices, social media, health care applications, and various other software applications and digital devices that continuously generate large amounts of structured, semi-structured or unstructured, data is strongly increasing rapidly. This massive data generation results in ``big data'' . Previous traditional database systems are not sufficient when storing, analyzing, and processing rapidly growing amount of data or big data . The term ``big data'' has been used in business and IT sectors.An example of big data-related studies is the next frontier for innovation, competition, and productivity; McKinsey Global Institute  defined big data as the size of data sets that are a better database system tool than the usual tools for capturing, storing, processing, and analyzing such data . ``The Digital Universe'' study  labels big data technologies as a new generation of technologies and architectures that aim to take out the value from a massive volume of data with various formats by enabling high-velocity capture, discovery, and analysis. This previous study also characterizes big data into three aspects:
(a) data sources, (b) data analytics, and (c) the presentation of the results of the analytics.
BI analytics is used when the size of data is more than the memory level, but in tht case, data may be imported to the BI analysis environment . BI analytic is currently supports by TB-level data . Moreover, BI can help discover strategic business opportunities from the flood of data.

4. Fog Computing
The number of devices being connected to the Internet is tremendously increasing. The device being connected to Internet is only due to advancement in the field of electronics and telecommunication field. The devices that are being connected are powerful in the sense that these device are able to communicate with each other .This type of communication is called M2M communication or Machine to Machine communication. In other words this paradigm is known as Internet of Things. The devices being referred to as ―Things include sensors, physical devices for performing various tasks. We can define IoT as network of physical objects embedded with software, electronics, sensors to achieve value and service by exchanging data with operators, connected devices through various protocols without any human interaction and involvement. With the increased number of devices being connected to each other the data produced by the devices is also huge which is transferred through the network to the Internet. In IoT cloud plays an important role. The word Cloud Computing has been in the market for so many years now and various researches and advancements have been done in the field of cloud computing. In IoT one of the benefits we get from the cloud is the flexibility the user gets in accessing the services offered by the cloud providers through user interfaces. The cloud can pose a problem for latency sensitive applications as IoT requires mobility support and geo distribution in addition to low latency and location awareness. So a new platform is needed called Fog. Fog extends cloud to the edge of the network. The term fog computing was introduced by Cisco in 2014. It was introduced so that it addresses applications which do not fit the paradigm of the cloud.
