How to get started with Big Data: A Beginner's Guide

Big Data is a term that describes the sheer volume of data, both structured and unstructured, that floods businesses every day. This collection and analysis of extremely large and complex data sets is beyond the capability of traditional software tools.

Data can originate from any source, such as social networks, sensors, online transactions, health records, and others. And it needs to be analyzed to find answers that enable cost reductions, time, optimized new product development and offerings, and intelligent decision making.

Big Data systems can help companies understand and improve their operations, get to know their customers better, create personalized products, and navigate the complex cybersecurity landscape, i.e., this analysis allows you to stay ahead of the curve and improve each customer's experience. In addition to identifying what information is relevant to the business processes and future needs of the company.

Big Data is also changing the way people live and work together. It encompasses the evolution of the Internet and the amount of information that is available to the public. With the exponential growth of data, the idea of manually storing it is not appealing or cost effective. Big Data datasets cannot be processed in traditional database management systems and tools. They do not fit into a regular database network.

As organizations continue to generate large amounts of data, the demand for Big Data professionals who can analyze and derive valuable information from this data is growing rapidly, becoming a necessity for large companies, being responsible for revealing valuable information, hidden patterns and trends of customers, users, and citizens, becoming a valuable aid for companies and public agencies to make informed and strategic decisions.

Among the sectors that use Big Data the most are e-commerce, healthcare, finance, manufacturing, and advertising, where it is used to understand customer behavior, optimize operations, predict market trends and improve decision making.

Working with Big Data is a challenge for professionals who do not have extensive knowledge in various areas, according to experts, you need knowledge of:

  • Programming fundamentals: knowledge in programming languages such as Python or Java are essential to manipulate data and create algorithms for Big Data analysis.
  • Mathematics and statistics: A solid understanding of mathematical and statistical concepts is crucial for data analysis.
  • Databases: Knowing the basics of databases and query languages such as SQL is essential for managing and accessing data efficiently.
  • Essential tools for Big Data: Data processing software that allow operating with large volumes of data in real time are necessary for the analysis of collected data. Among the most widely used are:
    • Apache Hadoop: An open source framework that allows the processing of large volumes of data. It is known for its scalability and security, and is used by companies such as Facebook and The New York Times.
    • Elasticsearch: A tool that facilitates the processing and visualization of large amounts of data in real time, providing graphics for a better understanding of the information.
    • R Language: A programming language used for statistical calculations and graphics, very popular among statistics professionals due to its collaborative nature and open source license.
    • Apache Spark: Known for its ability to perform fast, in-memory data analysis, Spark is an essential tool for real-time data processing.
    • Python: Although not a tool unique to Big Data, Python is widely used in data analytics due to its simplicity and the wide range of data libraries available.

Big Data is expected to transform not only the way we relate to the environment around us, but our lifestyles and even our cities.
