In recent year, the use of the internet and cloud-based application has increased tremendously. With this lot of internet apps and social network have been developed. This apps and networks are growing very rapidly. Data on this network belongs to different data sizes and structures. This data in simple language is called big data. With the increasing demand for services, all the big data services are now automated, which stores and retrieve consumer's data. This data is in a different structure which makes it difficult to handle. This can include an example of road traffic data, different vehicle or person or location or atmosphere can produce a different set of data. Sometimes this data is structured while some times it may contain repeated, null or noisy data. This data may contain images and videos. The traditional database cannot handle this type of unstructured data. The best to solve this dimensionality problem is by using a dimensionality reduction technique. This paper provides the concept of big data collection, its analysis, storage and handling issues, security challenges, and other data handling technique.
