What is Big Data Research?

Big Data Research is the study of how to collect, store, process, and analyse massive amounts of data to uncover useful patterns, trends, and insights. It focuses on solving real-world problems by using advanced technologies and methods.

Big Data refers to datasets so large and complex that traditional tools like spreadsheets or basic databases cannot handle them. Examples include data from social media, weather sensors, medical records, and online shopping platforms.

Big Data Research explores topics such as:

1. Data Storage: Finding better ways to store and manage huge volumes of data.
2. Data Analysis: Using tools like machine learning and artificial intelligence to find hidden patterns in data.
3. Data Visualisation: Turning complex data into easy-to-understand charts and graphs.
4. Applications: Using Big Data to improve healthcare, business, transportation, and more.
5. Ethics and Privacy: Ensuring data is used responsibly and securely.

For example, Big Data Research can help predict natural disasters, recommend movies on Netflix, or detect fraud in banking. It combines fields like computer science, statistics, and domain knowledge to make smarter decisions and solve global challenges.

How do I choose a research topic in data science?

To choose a research topic in data science:

1. Identify your interests: Focus on areas you are curious about, like healthcare, finance, or social media.
