Abstract
Big data analysis techniques are the methods and tools utilized for extracting insights and knowledge from vast and intricate datasets. Due to the increasing velocity, volume, and variety of data being produced, conventional data analysis methods have become inadequate. Therefore, big data analysis techniques employ advanced computational and statistical methods to extract treasured information from big data. There are several big data analysis techniques, including data mining, natural language processing, machine learning, predictive analytics, and deep learning. For example, data mining involves identifying patterns and relationships within data sets, while machine learning enables systems to learn from data without explicit programming. Additionally, natural language processing focuses on analyzing human language, and predictive analytics utilizes statistical modeling techniques to predict future outcomes. Deep learning, which uses neural networks to model complex data patterns, is also a common big data analysis technique.
Top1. Introduction
Big data analysis is a process of examining and interpreting massive and complex datasets to extract valuable insights, enabling decision-makers to make informed decisions. “Big data” describes datasets too large or complicated for conventional data processing tools to handle. Advanced software and hardware tools are used in big data analysis to collect, store, process, and analyze large datasets using various analytical techniques, which includes statistical analysis, machine learning, data mining, and natural language processing.
The insights obtained through big data analysis which can be used to inform decision-making in multiple industries and applications, such as healthcare, finance, marketing, and manufacturing. For example, healthcare providers can identify patterns in patient data, leading to more effective diagnosis and treatment. Retailers can analyze customer purchase patterns and create better marketing strategies.
Big data analysis has become prevalent as a result of the substantial increase in data volume originating from digital technologies like mobile devices, social media and Internet of Things (IoT). By utilizing these massive datasets, organizations can obtain a deeper understanding of their customers, operations, and markets, resulting in better decision-making and improved business outcomes.
Big data analytics involves identifying problem, gathering relevant data from diverse sources, storing it in scalable infrastructures, cleaning and preprocessing the data, integrating multiple datasets, exploring and analyzing the data using statistical and machine learning techniques, evaluating and validating models, interpreting and visualizing insights, and utilizing those insights for decision making and value creation as shown in below Figure1.

In today's data-driven economy, big data analysis serves as a powerful tool for organizations aiming to extract the value from their data and secure a competitive edge.
1.1 Definition and Overview of Big Data Analysis
The term “big data analysis” refers to the procedure of analyzing and interpreting datasets that are too large, complex, or heterogeneous for traditional data processing tools to handle. This process involves using advanced software and hardware tools to collect, store, process, and analyze large datasets with a variety of analytical techniques, like statistical analysis, data mining, machine learning, and natural language processing.
The insights gained from big data analysis can inform decision-making across many industries, including healthcare, finance, marketing, and manufacturing. As an example, healthcare providers can employ big data analysis to recognize patterns within patient data, aiding in improved disease diagnosis and treatment approaches. Similarly, retailers can use big data analysis to evaluate customer purchasing patterns and develop more effective marketing strategies.
The advent of big data analysis is due to the explosion of data produced by digital technologies like social media, mobile devices, and the Internet of Things (IoT). By analyzing these massive datasets, organizations can gain deeper insights into their customers, operations, and markets, which can enhance decision-making and improve business outcomes.
