API Management Fundamentals for Architects Training

Data engineering is a software engineering practice with focus on design, development, and the productionizing of data processing systems.  It includes all the practical aspects of data acquisition, transfer, transformation, and storage on-prem or in the cloud.
This intensive hands-on training course teaches the students how to apply Python to the practical aspects of data engineering and introduces the students to the popular Python libraries used in the field, including NumPy, pandas, Matplotlib, scikit-learn, and Apache Spark.  


  • Data engineering practice
  • High-octane introduction to Python
  • Technical reviews of NumPy, pandas, and other Python libraries and data processing systems
  • Data visualization and exploratory data analysis
  • Data repairing and normalization
  • Understanding the data needs and requirements of Machine Learning and Data Science projects
  • Python in the Cloud
  • Python on Hadoop (PySpark)


Developers, Software Engineers, Data Scientists, and IT Architects


Participants are expected to have practical experience coding in one or more modern programming languages.  Knowledge of Python is desirable but not necessary.  The students are expected to be able to quickly learn the new material, reinforce the knowledge of a learned topic by doing programming exercises (labs), and then apply their knowledge in data engineering mini projects.
