Big Data technologies include Hadoop, Spark, and NoSQL databases. Unstructured Data: Data with no predefined format (like text documents, social media posts, images, audio files, videos). Big Data Technologies Enable Data Science at Scale Tools like Hadoop and Spark were developed specifically to handle the challenges of Big Data.
Evaluate Community Support and Documentation A strong community around a tool often indicates reliability and ongoing development. Evaluate the availability of resources such as documentation, tutorials, forums, and user communities that can assist you in troubleshooting issues or learning how to maximize tool functionality.
MongoDB MongoDB is a NoSQL database that stores data in flexible, JSON-like documents. TableauTableau is a popular data visualization tool that enables users to create interactive dashboards and reports. Apache Hive Apache Hive is a data warehouse tool that allows users to query and analyse large datasets stored in Hadoop.
Architecturally the introduction of Hadoop, a file system designed to store massive amounts of data, radically affected the cost model of data. Organizationally the innovation of self-service analytics, pioneered by Tableau and Qlik, fundamentally transformed the user model for data analysis. Disruptive Trend #1: Hadoop.
Processing frameworks like Hadoop enable efficient data analysis across clusters. This includes structured data (like databases), semi-structured data (like XML files), and unstructured data (like text documents and videos). Key Takeaways Big Data originates from diverse sources, including IoT and social media.

Key Takeaways Big Data originates from diverse sources, including IoT and social media.
These packages allow for text preprocessing, sentiment analysis, topic modeling, and document classification. Packages like dplyr, data.table, and sparklyr enable efficient data processing on big data platforms such as Apache Hadoop and Apache Spark. You can simply drag and drop to complete your visualisation in minutes.
Because they are the most likely to communicate data insights, they’ll also need to know SQL, and visualization tools such as Power BI and Tableau as well. Some of the tools and techniques unique to business analysts are pivot tables, financial modeling in Excel, Power BI Dashboards for forecasting, and Tableau for similar purposes.
documents and images). By consolidating data from over 10,000 locations and multiple websites into a single Hadoop cluster, Walmart can analyse customer purchasing trends and optimize inventory management. Data can be structured (e.g., databases), semi-structured (e.g., XML files), or unstructured (e.g.,
Unstructured Data: Data without a predefined structure, like text documents, social media posts, or images. Tableau/Power BI: Visualization tools for creating interactive and informative data visualizations. Hadoop/Spark: Frameworks for distributed storage and processing of big data.
Gain Experience with Big Data Technologies With the rise of Big Data, familiarity with technologies like Hadoop and Spark is essential. Learn to use tools like Tableau, Power BI, or Matplotlib to create compelling visual representations of data. Additionally, familiarity with cloud platforms (e.g.,
Classification techniques, such as image recognition and document categorization, remain essential for a wide range of industries. Hadoop, though less common in new projects, is still crucial for batch processing and distributed storage in large-scale environments. Kafka remains the go-to for real-time analytics and streaming.
Accordingly, it is possible for the Python users to ask for help from Stack Overflow, mailing lists and user-contributed code and documentation. Tools such as Matplotlib, Seaborn, and Tableau may help you in creating useful visualisations that make challenging data more readily available and understandable to others.
