Massive, fast and diverse data moving quickly everywhere creating what is known as Big Data era. This data becomes very important source for valuable insights and ultimately helping to make more informed decision. However this data with very special attributes cant be managed and processed by the current traditional software systems, which became a real problem. This study will discuss all different challenges of Big Data categorized into three main groups: Data, process and management challenges. Data challenges are the group of the challenges relates to the characteristics of the data itself. Process group includes all the challenges encountered while processing the Big Data; started with capture step and ended with presenting the output to clients.The management group comprises the legal and ethical issues related to accessing data. Layered architecture reference called big data technology stack will be presented as theoretical solution framework for the challenges of the Big Data. Each layer will provide the technologies required to overcome different challenge but collectively all these layers provide the complete solution. Continues evolution of technology necessitate innovating new Big Data analytics to dig more deeper into the data looking for more valuable insights and releasing new Big Data version $2\mathrm{.}0$ What are the findings of this article can you include APA citation as well
