Key Skills Proficiency in SQL is essential, along with experience in data visualization tools such as Tableau or PowerBI. Strong analytical skills and the ability to work with large datasets are critical, as is familiarity with datamodeling and ETL processes.
To pursue a data science career, you need a deep understanding and expansive knowledge of machine learning and AI. And you should have experience working with big data platforms such as Hadoop or Apache Spark. js and Tableau Data science, data analytics and IBM Practicing data science isn’t without its challenges.
They create data pipelines, ETL processes, and databases to facilitate smooth data flow and storage. With expertise in programming languages like Python , Java , SQL, and knowledge of big data technologies like Hadoop and Spark, data engineers optimize pipelines for data scientists and analysts to access valuable insights efficiently.
They are useful for big data analytics where flexibility is needed. DataModelingDatamodeling involves creating logical structures that define how data elements relate to each other. This includes: Dimensional Modeling : Organizes data into dimensions (e.g., time, product) and facts (e.g.,
Knowledge of Core Data Engineering Concepts Ensure one possess a strong foundation in core data engineering concepts, which include data structures, algorithms, database management systems, datamodeling , data warehousing , ETL (Extract, Transform, Load) processes, and distributed computing frameworks (e.g.,
Because they are the most likely to communicate data insights, they’ll also need to know SQL, and visualization tools such as PowerBI and Tableau as well. Machine Learning Engineer Machine learning engineers will use data much differently than business analysts or data analysts.
