Data Scientist: Data scientists are responsible for collecting, cleaning, and analyzing large datasets to extract valuable insights and make data-driven decisions. They use various machine learning and statistical techniques to build predictive models and solve complex problems.Data scientists often work closely with business stakeholders to identify opportunities for leveraging data to drive business growth.
Data Analyst: Data analysts focus on examining data to provide actionable insights to their organizations. They perform data cleaning, data visualization, and basic statistical analysis to help businesses understand trends, patterns, and make informed decisions.
Data analysts may work in various industries such as finance, marketing, or healthcare.Data Engineer: Data engineers are responsible for the design, construction, and maintenance of data pipelines and infrastructure. They ensure that data is collected, stored, and made accessible for analysis by data scientists and analysts.
Data engineers work with tools like Hadoop, Spark, and databases to manage and process large volumes of data efficiently.Data Architect: Data architects design the overall structure and organization of data within an organization. They create data models, define data standards, and ensure data is stored, integrated, and accessed effectively.
Data architects play a critical role in establishing data governance and ensuring data quality.Machine Learning Engineers: Machine Learning Engineers are responsible for designing, building, and deploying machine learning models and systems. Their primary focus is on developing algorithms and systems that can learn from and make predictions or decisions based on data.
The field of data science is continually evolving, so there are always new opportunities and roles emerging as technology advances and businesses become more data-driven. It's important to choose a path that aligns with your interests and career goals.
Let's explore the skills and qualifications required for a career as a data engineer, focusing on their role in ensuring the collection, storage, and accessibility of data for analysis by data scientists and analysts
ETL (Extract, Transform, Load): Expertise in ETL processes to extract data from various sources, transform it into the desired format, and load it into data storage or data warehouses.
Data Modeling: Ability to create efficient and scalable data models for databases and data warehouses.
Knowledge of distributed systems like Hadoop and Spark as well as cloud computing platforms such as Azure and AWS
Data analysis: Understanding of analytics software, specifically Apache Hadoop-based solutions like MapReduce, Hive, Pig and HBase. A primary focus for engineers is to build systems that gather information for use by other analysts or scientists. Having strong analysis skills yourself can help you create such systems and improve them.
You’ll also need to familiarize yourself with various data-related programs and languages. Here are some known ones:
Python
Apache Hadoop and Apache Spark
SQL
Amazon Web Services
Azure
