Data Processing and Transformation
Data processing and transformation involve the cleaning, enrichment, and shaping of raw data into a format that is suitable for analytics. Data engineers use tools and technologies such as Apache Spark, Apache Flink, and Apache Beam to process and transform the data, as well as implementing data pipelines and workflows for automation.
Plus, data processing and transformation also include the implementation of data governance practices to ensure that the processed data meets the required quality and regulatory standards, as well as data lineage and metadata management to track the data transformation process.
Data Quality and Governance
Data quality and governance processes are put in place to ensure that the data used for analytics is accurate, consistent, and reliable. Data engineers implement data quality checks, data validation, and data profiling to identify and address any issues in the data. They also establish data governance policies and procedures to ensure compliance with regulations and standards, as well as data security and privacy measures to protect the data.
Data governance also involves the implementation of data access controls, data lineage tracking, and auditing to monitor and control the access and usage of data, ensuring that the data is used responsibly and ethically.
Tools and Technologies in Data Engineering
Your journey into the world of data engineering will introduce you to a vast array of tools and technologies that support the processing, storage, and analysis of big data.
