It improves the overall quality of data, which helps in better decision-making.

6. Big Data

Big data is a term used for large and extremely complex data sets. These data sets are too large to be analyzed using traditional software. Hence, it becomes important for data scientists in the 21st century to be aware of important tools and algorithms that they can use to deal with big data. Frameworks like Hadoop and Apache Spark are suitable for managing such large structured and unstructured data sets.

7. Data Processing

Data processing refers to collecting and transforming data in an easy-to-handle format. Different stages included in data processing are data collection, data preparation, data input, processing, data output, and data storage. Data scientists should be very well-versed in data processing. They should be very careful while performing data processing as any inaccuracies in data processing can affect the end result negatively.

8. Data Visualization

Data visualization is the process of representing textual or numerical data in the form of visuals to make it interesting and easier to understand for the human mind. As a data scientist, you should have knowledge of important data visualization techniques and tools like Tableau.

Deep learning, which is a sub-domain of ML, is also a crucial skill for data science professionals. It is useful in creating algorithms that can recognize patterns in data by studying multiple layers of artificial neural networks.

12. Neural Networks

Neural networks are artificial structures with various interconnected nodes that resemble the neuron system of a human brain. These networks are used to enable machines to make decisions like humans. Neural networks can be used to categorize raw data and recognize hidden patterns in it. These artificial neurons learn continuously and improve themselves over time. Data Scientists must be aware of what neural networks are and how they are used.

13. Data Warehousing

Data warehousing is the process of integrating information and data collected from different sources into one database. Many professionals confuse data warehouses with databases. However, the two are not the same. A database only stores current data whereas a data warehouse stores current as well as historical data. Data scientists should have a good knowledge of data warehousing and ETL (Extract, Transform, and Load).

14. SQL and Database Management

SQL is a programming language that data scientists use to deal with SQL databases and perform data storage tasks. SQL allows you to access structured data and manipulate it. It is closely related to database management, which is the process of organizing, storing, and fetching data from a particular place.
