Top 10 Big Data Skills to Have in 2024

In order to land a job in this rapidly changing industry, it is important to have the ten necessary big data skills that will make you stand out from other applicants.

  • Problem-Solving 
  • Programming Languages  
  • Data Structures and Algorithms
  • SQL and NoSQL Databases
  • Data Warehousing
  • Data Mining
  • Distributed Frameworks
  • Cloud Computing
  • Interpretation and Data Visualization 
  • Machine Learning

Problem-Solving

Big data specialists must possess excellent problem-solving skills to address challenges related to data quality, scalability, privacy, and computing efficiency. They need to devise creative solutions to optimize data processing procedures. Not only that, they also need strong quantitative analysis and analytical skills which are crucial for extracting valuable insights from massive datasets through statistical analysis, hypothesis testing, and mathematical modeling. These skills facilitate data-driven decision-making and pattern recognition.

An essential tool to master before learning any other big data technology to master problem-solving skills is Excel. Microsoft Excel is a simple yet effective analytical tool to store data and analyze it. Mastering Excel will help any big data professional to hone their problem-solving skills.

Programming Languages

Pprogramming languages are extremely important for any big data professional. Every big data engineer will be involved with designing and building pipelines. For this, it is crucial for a big data professional to know the ins and outs of programming.

There is not a set programming language that a big data professional needs to know. However, knowledge of any popular language from the likes of Python, Java, or Scala would be good enough.

Data Structure and Algorithms

Now, knowledge of programming languages is one thing but how to write efficient code is another. Writing efficient code is important to optimize the storage utilization to handle big complex data. For this, we have the concepts of data structures and algorithms which are the cornerstones of computer science.

These concepts are extremely important for big data professionals. For example, how would you sort an array containing millions of records? If you go by the brute force method, you will end up utilizing a lot of unnecessary resources. Or let’s say, how can you efficiently store a sparse array? To know the answers to such real-life problems you need to understand data structures and algorithms.

SQL and NoSQL Databases

Structured Query Language or SQL is a query language to manage data in a relational database. These databases store data in a structured format within rows and columns. MySQL and PostgreSQL are the two most popular SQL databases.

On the other hand, not all data can be incorporated strictly within a structured table. Also, SQL databases will not be suitable for all purposes as they lack data throughput speed and flexibility to store unstructured data. For these reasons, there are different kinds of databases known as NoSQL databases specially designed for such purposes. MongoDB and Cassandra are two such databases. You can have a look at NoSQL databases in this article.

Explore the top 10 SQL projects here.

Data Warehousing

Besides databases, it is also important for big data professionals to be proficient in working with data warehouses. Data warehouses are different from simple databases as they are specially designed to store data for analytical purposes.

Data stored in data warehouses is already aggregated from raw data and is ready to be consumed by data analysts. You will need to learn about data warehousing design architecture like Star and Snowflake schemas and when to use which one.

Hive is a very popular data warehouse tool. You can learn about Hive in this article.

Data Mining

For big data professionals, data mining is crucial. It enables the extraction of meaningful insights from vast datasets through techniques like association rule mining, classification, and clustering. By uncovering patterns and anomalies, data mining facilitates informed decision-making across industries like business, finance, and healthcare. Data mining enhances predictive modeling and trend forecasting, enabling professionals to derive actionable insights and drive strategic initiatives. It’s a cornerstone for unlocking the potential of big data, allowing professionals to harness its power for innovation and competitive advantage.

Explore these top 14 data mining projects.

Distributed Frameworks

Big data professionals or data architects work with distributed systems because big data cannot be stored and processed on a single machine. Single machines are prone to fail and can quickly overcome their storage.

There are a lot of distributed frameworks the most important of which is Apache Hadoop. Apache Hadoop has an ecosystem of tools serving various purposes. It has HDFS which is the distributed storage layer storing data in various worker nodes and handling fault tolerance. Then it has the MapReduce component responsible for the distributed processing of big data. Then it has components like Sqoop, HBase, etc. on top for handling the data. You can check out all of that over here.

Besides Hadoop, there is also Apache Spark which is more efficient than Hadoop in processing the data. It is much faster as it handles data in memory thereby reducing the input-output operations happening in MapReduce. You can read about Apache Spark in this article.

Cloud Computing

The task of a big data professional is essentially to design an architecture to manage and store big data. Now this architecture can be designed on-premise. However, given the low cost of resources on the cloud, a lot of organizations are moving their infrastructure to platforms like AWS, Azure, or GCP. Therefore, it is extremely important for big data professionals to understand the cloud platforms really well to effectively utilize the resources and design cost-effective pipelines.

Interpretation and Data Visualization

Effectively understanding and visually presenting data insights are vital for engaging stakeholders. Data visualization skills enable the development of relevant graphs, charts, and dashboards that aid in comprehension and decision-making. For this purpose, it is important to learn tools like Tableau or PowerBI. You can

Machine Learning

Besides learning big data technologies, big data engineers also need to learn about data science machine learning, and deep learning algorithms. This is important because the end user of any data warehouse or database is a data scientist. So if a big data engineer has good knowledge of machine learning algorithms, they will have a clear understanding of the data requirements from a data scientist or a data analyst. This will reduce the knowledge gap between the two and smooth out the automation process. So having knowledge of basic algorithms like linear regression, logistic regression, KNN, SVM, Neural Networks, CNNs, etc. will go a long way in a big data professional’s career.
