Various phases involved in big data analytics


There is no single answer to the question of what constitutes big data analytics. However, there are a few key elements that are usually involved. In general, big data analytics refers to the process of examining large and complex data sets in order to uncover hidden patterns, trends, and relationships. The goal is to Transform Data Into Game-Changing Insights.

This process usually involves the following steps:
1) Data Collection: This is the first and most important step in any big data analytics project. It involves gathering data from a variety of sources, including social media, transaction records, sensors, and so on.
2) Data Processing: Once the data has been collected, it needs to be processed in order to be usable for analysis. This usually involves cleaning up the data, converting it into a format that can be analyzed, and so on.
3) Data Analysis: This is where the actual work of analyzing the data takes place. Big data analytics tools and techniques are used to examine the data in order to identify patterns, trends, and relationships.
4) Data Visualization: Once the analysis is complete, it is often helpful to visualize the results in order to make them easier to understand and interpret. This can be done using various graphical techniques such as charts, graphs, maps, and so on.
5) Decision Making: The final step in the process is to use the insights gained from the analysis to make better decisions. This could involve anything from changing business strategies to improving customer service or increasing operational efficiencies.

Data Acquisition

There are various phases involved in big data analytics, and data acquisition is one of the most important ones. This is the process of gathering data from various sources, both internal and external, and then storing it in a centralized location. This data can then be used for further analysis and decision making.

There are a number of methods that can be used for data acquisition, and the most commonly used ones are discussed below:

  1. Data scraping: This is a process of extracting data from websites or other online sources. This can be done manually or through the use of automated tools.
  2. Data mining: This is a process of extracting valuable information from large datasets. This can be done through the use of algorithms or other methods.
  3. Database queries: This is a process of retrieving specific information from databases using query languages such as SQL.
  4. Manual entry: This is a process of manually entering data into a computer system for storage and further analysis.
    Data Preparation

    Data preparation is one of the most important phases in any big data analytics project. It is the process of cleaning, transforming and staging data so that it can be ready for further analysis and interpretation.

This phase involves tasks such as data quality checks, outlier detection and removal, data normalization, data transformation and feature engineering. Data preparation is a critical step in ensuring that the results of the analytics project are accurate and meaningful.

Data Exploration

Once data is collected, the next step is to explore it and try to understand what it contains. This involves identifying patterns, trends and relationships within the data. Data exploration can be done manually, but it is often more efficient to use specialized software tools that can help to reveal hidden insights.

After exploring the data, the next step is to prepare it for analysis. This may involve cleaning the data to remove errors or outliers, and transforming it into a format that is more suitable for the planned analysis.

Data Modelling

The big data analytics process usually starts with data modeling. Data models help you understand the structure of your data and relationships between different data sets. You can use data models to organize and simplify complex data sets.

Once you have a data model, you can start to analyze your data. There are many different ways to analyze data, but some common methods include:

-Descriptive analytics: Descriptive analytics summarize your data and help you understand what it means. This type of analysis can help you find trends and patterns in your data.
-Predictive analytics: Predictive analytics use historical data to make predictions about future events. This type of analysis can help you make decisions about marketing campaigns, product development, and other strategic decisions.
-Prescriptive analytics: Prescriptive analytics go one step further than predictive analytics. In addition to making predictions about future events, prescriptive analytics also provide recommendations about what actions you should take to achieve specific goals.

Data Visualization

Data visualization is the process of transforming raw data into a graphic representation. This can be done using a variety of techniques, including charts, diagrams, and infographics. Data visualization is an important part of data analysis, as it allows analysts to quickly identify trends and patterns in large data sets. It also makes complex data sets more accessible to non-technical users.


The success of big data analytics depends on 4 key phases – data collection, data preparation, model building, and deployment. Together, these phases can help organizations extract valuable insights from their data and make better business decisions.

Data collection is the first phase of big data analytics. In this phase, organizations collect data from various sources, including social media, website logs, and sensors. This data is then stored in a central repository for further processing.

Data preparation is the second phase of big data analytics. In this phase, organizations clean and prepare the data for analysis. This includes tasks such as remove duplicate records, filling in missing values, and transforming the data into a format that can be easily analyzed.

Model building is the third phase of big data analytics. In this phase, organizations build statistical models to find relationships between variables in the data. These models can then be used to make predictions or recommendations about future events.

Deployment is the fourth and final phase of big data analytics. In this phase, organizations deploy the models they have built into production systems. This deployment can be done either manually or automatically. Once deployed, these models can be used to make real-time decisions about future events
