Big data

What is Big Data Analytics & what are its types?

The often challenging process of analysing large amounts of data to find information that might assist businesses in making wise decisions about their operations, such as previously unknown patterns, correlations, market trends, and customer preferences, is known as big data analytics.

Organisations can analyse data sets and gain new insights using data analytics technology and processes. Basic inquiries regarding business performance and operations are addressed by business intelligence (BI) queries.

Advanced analytics, which includes aspects like predictive models, statistical algorithms, and what-if analysis driven by analytics systems, is a subset of big data analytics.

Why Big Data Analytics is Crucial?

Big data analytics technologies and software can help organisations make data-driven choices that can enhance the results of their business operations.

Benefits could include enhanced consumer personalisation, increased operational effectiveness, and more effective marketing. These advantages over competitors can be achieved with a strong strategy.

Data Analytics Processing:

Growing quantities of structured transaction records as well as other types of data not used by traditional BI and analytics tools are collected, processed, cleaned, and analysed by data analysts, data analysts, predictive modelers, statisticians, and other analytics specialists.

The basic stages of the big data analytics method are summarised as follows:

1. Data experts assemble data from a wide range of sources. Frequently, semi-structured and unstructured data are combined. Although each firm will employ different data streams, the following are some typical sources:

2. Internet clickstream data, web server logs, cloud applications, mobile applications, social media content, text from emails and survey responses, records of mobile phones, and machine data collected by sensors linked to the internet of things are just a few examples of the data that can be collected (IoT).

3. Data preparation and processing occur. Data experts must correctly organise, configure, and segment the data for analytical queries after it has been acquired and stored in the data warehouse or data lake. The performance of analytical queries is improved by careful data preparation and processing.

4. To increase its quality, data is cleaned. Data cleaning specialists use scripting techniques or data quality software to clean the data. They organise and clean up the data while looking for any duplications or formatting flaws that may have occurred.

Analytics software is used to examine the data that has been gathered, prepared, and cleaned. There are tools for:

1. Data mining is the process of poring over data collections to look for patterns and relationships.

2. Predictive analytics, which creates models to foresee customer behavior as well as other potential future events, scenarios, and trends. Using different methods, machine learning can examine huge data sets.

3. Text analytics and statistical analysis are two more sophisticated applications of machine learning called “deep learning.” Software

4. Business intelligence software that uses artificial intelligence (AI)

5. Data visualisation tools

Big Data Analytics – Important Technology and Techniques:

Processes for big data analytics involve a wide variety of tools and technologies. The following technologies and techniques are frequently used to support big data analytics processes:

1. The open-source Hadoop framework is used to store and handle large amounts of data. Large volumes of unstructured and structured data can be handled with Hadoop.

2. Predictive analytics hardware and software use machine learning and statistical algorithms to forecast the results of future events after processing vast volumes of complex data. Tools for predictive analytics are used by businesses in operations, marketing, risk assessment, and fraud detection.

3. Tools for stream analytics are used to filter, aggregate, and analyse massive data, which may be stored on a variety of platforms or in a variety of different formats.

4. Replicated distributed storage data is typically seen in non-relational databases. Providing low-latency access or protecting against separate node failures, and lost or damaged huge data, are some examples of possible uses for this.

5. When dealing with big distributed data sets, NoSQL databases—non-relational data management systems—come in handy. They work best with unstructured and raw data because they don’t need a set format.

6. A data lake is a sizable storage facility where raw data in native formats are kept until they are required. A flat architecture is used by data lakes.

7. A data warehouse is a repository used to keep vast amounts of data that have been gathered from various sources. Data warehouses often utilise predetermined schemas to store data.

8. Utilising tools for knowledge discovery and big data mining, enterprises can mine vast quantities of both unstructured and structured data.

Large volumes of data are distributed among system memory resources via an in-memory data network. Low latency for access to data and processing is made possible by this.

9. Data virtualisation makes it possible to access data without any technical limitations. 

10. Big data may be optimised across numerous platforms, like Apache, Hadoop, MongoDB, and Amazon EMR, thanks to data integration tools.

Large data sets are cleaned and enhanced using data quality software.

11. software for preparing data so that it is ready for additional analysis. Unstructured data is cleaned, and data is prepared.

For processing batch and stream data, there is a cluster computing framework called Spark, which is a free source.

Applications for big data analytics frequently use information from both internal and external sources, including weather information or customer demographic data provided by outside information services providers. Additionally, as customers try to perform real-time analysis on data streamed into Hadoop systems through streaming data engines, such as Spark, Flink, and Storm, streaming analytics applications are increasingly prominent in big data contexts.

The majority of early big data systems were installed on-site, especially in huge enterprises that gathered, arranged, and analysed enormous amounts of data. However, cloud platform providers like Amazon Web Services (AWS), Google, and Microsoft have simplified the process of setting up and managing Hadoop clusters on the cloud. The same is true for Hadoop providers like Cloudera, which supports the big data framework’s deployment across the AWS, Google, and Microsoft Azure clouds.

With utilisation pricing that does not require ongoing software licenses, users may now instantly set up clusters in the cloud, use them for whatever length they are required to, and then take them offline.

Supply chain analytics has benefited greatly from big data. Big supply chain analytics uses quantitative approaches and big data to improve decision-making throughout the supply chain. Big supply chain analytics, in particular, broadens data sets for increased analysis beyond the conventional internal data available on ERP and SCM systems. Big supply network analytics also applies very efficient statistical techniques to both fresh and old data sources.


Here are a few instances of how big data analytics may benefit businesses:

Acquisition and retention of customers. Companies’ marketing initiatives can benefit from consumer data so they can take advantage of trends and improve customer satisfaction. Personalisation tools for services like Spotify, Netflix, and Amazon, for instance, can enhance user loyalty and experiences.

Advertisements that are specifically aimed. Users can benefit from effective targeted ad campaigns that are created for them both on an individual level and a broader scale using personalisation data from various sources including prior purchases, interaction patterns, and custom page viewing histories.

Product creation. Big data analytics can offer information to help with product viability, development choices, progress tracking, and guiding improvements toward what works for a company’s clients.

Price reduction. To increase profits, retailers may choose pricing models that model and utilise data from various data sources.

Channel and supply chain analytics. Predictive analytical models can assist with proactive restocking, B2B supplier networks, inventory control, route improvements, and delivery delay notice.

Risk control. Effective risk management techniques can be developed using big data analytics to find new dangers in data trends.

More effective decision-making. Businesses may make better and quicker decisions with the help of the insights business users derive from pertinent data.
