Updated in [June 30th, 2023]

This course provides an overview of how to use PySpark to clean complex real-world data. Participants will learn the fundamentals of pipelines and the significance of data cleaning. Additionally, different methods for modifying the contents of DataFrames in Spark will be discussed. By the end of the course, participants will have the knowledge to increase the efficiency of data cleaning tasks by increasing performance or lowering resource requirements.

[Applications]
After completing this course, students should be able to apply the knowledge they have gained to their own data cleaning tasks. They should be able to use Spark to process complex real-world data and understand the fundamentals of pipelines. Additionally, they should be able to modify the contents of DataFrames in Spark and increase the efficiency of data cleaning tasks by increasing performance or lowering resource requirements.

[Career Path]
The career path recommended to learners of this course is that of a Data Engineer. Data Engineers are responsible for designing, building, and maintaining data pipelines and architectures. They are also responsible for ensuring that data is properly collected, stored, and processed. Data Engineers must have a strong understanding of data structures, algorithms, and software engineering principles. They must also be able to work with a variety of data sources and technologies, such as PySpark, Hadoop, and Apache Spark.

The development trend for Data Engineers is to become more specialized in their field. As data becomes more complex and data sources become more varied, Data Engineers must be able to work with a variety of technologies and data sources. They must also be able to develop and maintain data pipelines that are efficient and reliable. Additionally, Data Engineers must be able to work with data in a variety of formats, such as structured, semi-structured, and unstructured. As data becomes more complex, Data Engineers must be able to develop and maintain data pipelines that are efficient and reliable.

[Education Path]
The recommended educational path for learners of this course is to pursue a Bachelor's degree in Computer Science or a related field. This degree will provide learners with a comprehensive understanding of the fundamentals of computer science, including programming, data structures, algorithms, and software engineering. Additionally, learners will gain an understanding of the principles of data science, such as data mining, machine learning, and artificial intelligence.

The development trend of this degree is to focus on the application of computer science and data science to real-world problems. This includes the use of big data technologies such as Apache Spark, Hadoop, and NoSQL databases. Additionally, learners will gain an understanding of the principles of data engineering, such as data wrangling, data visualization, and data analysis. Finally, learners will gain an understanding of the principles of data governance, such as data security, data privacy, and data quality.
