Storage and retrieval of vast amount of data within a desirable time lag is a challenge. Though big data has gained attention due to the emergence of the Internet, but it cannot be compared with it. It is beyond the Internet, though Web makes it easier to collect and share knowledge as well data in raw form.

Top 6 Major Challenges of Big Data & Simple Solutions To Solve Them
The aim of this paper is to identify some of the challenges that need to be addressed to accelerate the deployment and adoption of smart health technologies for ubiquitous healthcare access. The paper also explores how internet of things IoT and big data technologies can be combined with smart health to provide better healthcare solutions. The authors reviewed the literature to identify the challenges which have slowed down the deployment and adoption of smart health. The authors discussed how IoT and big data technologies can be integrated with smart health to address some of the challenges to improve health-care availability, access and costs. The results of this paper will help health-care designers, professionals and researchers design better health-care information systems.
No organization can function without data these days. With huge amounts of data being generated every second from business transactions, sales figures, customer logs, and stakeholders, data is the fuel that drives companies. All this data gets piled up in a huge data set that is referred to as Big Data. This data needs to be analyzed to enhance decision making. But, there are some challenges of Big Data encountered by companies. These include data quality, storage, lack of data science professionals, validating data, and accumulating data from different sources. We will take a closer look at these challenges and the ways to overcome them.
Challenges of Big Data Analysis
Big data is a field that treats ways to analyze, systematically extract information from, or otherwise deal with data sets that are too large or complex to be dealt with by traditional data-processing application software. Data with many fields columns offer greater statistical power , while data with higher complexity more attributes or columns may lead to a higher false discovery rate. Big data was originally associated with three key concepts: volume , variety , and velocity. The analysis of big data presents challenges in sampling, and thus previously allowing for only observations and sampling. Therefore, big data often includes data with sizes that exceed the capacity of traditional software to process within an acceptable time and value.
This knowledge can enable the general to craft the right strategy and be ready for battle. Just like that, before going big data, each decision maker has to know what they are dealing with. Oftentimes, companies fail to know even the basics: what big data actually is, what its benefits are, what infrastructure is needed, etc. Without a clear understanding, a big data adoption project risks to be doomed to failure. Big data, being a huge change for a company, should be accepted by top management first and then down the ladder. To ensure big data understanding and acceptance at all levels, IT departments need to organize numerous trainings and workshops. To see to big data acceptance even more, the implementation and use of the new big data solution need to be monitored and controlled.

Challenges and Solutions for Processing Real-Time Big Data Stream: A Systematic Literature Review Abstract: Contribution: Recently, real-time data warehousing DWH and big data streaming have become ubiquitous due to the fact that a number of business organizations are gearing up to gain competitive advantage.
Metrics details. Big data analytics has gained wide attention from both academia and industry as the demand for understanding trends in massive datasets increases. Recent developments in sensor networks, cyber-physical systems, and the ubiquity of the Internet of Things IoT have increased the collection of data including health care, social media, smart cities, agriculture, finance, education, and more to an enormous scale. However, the data collected from sensors, social media, financial records, etc. As the amount, variety, and speed of data increases, so too does the uncertainty inherent within, leading to a lack of confidence in the resulting analytics process and decisions made thereof.

Big Data bring new opportunities to modern society and challenges to data scientists. On the one hand, Big Data hold great promises for discovering subtle population patterns and heterogeneities that are not possible with small-scale data. On the other hand, the massive sample size and high dimensionality of Big Data introduce unique computational and statistical challenges, including scalability and storage bottleneck, noise accumulation, spurious correlation, incidental endogeneity and measurement errors. These challenges are distinguished and require new computational and statistical paradigm. This paper gives overviews on the salient features of Big Data and how these features impact on paradigm change on statistical and computational methods as well as computing architectures. We also provide various new perspectives on the Big Data analysis and computation. In particular, we emphasize on the viability of the sparsest solution in high-confidence set and point out that exogenous assumptions in most statistical methods for Big Data cannot be validated due to incidental endogeneity.
Big Data has gained much attention from the academia and the IT industry. In the digital and computing world, information is generated and collected at a rate that rapidly exceeds the boundary range. Currently, over 2 billion people worldwide are connected to the Internet, and over 5 billion individuals own mobile phones. By , 50 billion devices are expected to be connected to the Internet. At this point, predicted data production will be 44 times greater than that in As information is transferred and shared at light speed on optic fiber and wireless networks, the volume of data and the speed of market growth increase.
