-
Requirements / Prerequisites
- Possess a foundational understanding of core data engineering concepts, including various database types (relational, NoSQL), data warehousing principles, ETL/ELT processes, and basic big data methodologies.
- Familiarity with cloud computing paradigms and services, specifically those relevant to data storage, processing, and analytics on at least one major cloud platform such as AWS, Azure, or Google Cloud Platform. While not a cloud-specific certification, most modern data engineering roles are cloud-centric.
- Proficiency in SQL for data manipulation and querying is essential. A basic working knowledge of scripting languages, particularly Python, is highly recommended as it often features in data engineering scenarios and problem-solving.
- Prior experience working with data or an academic background in computer science, data science, or a related technical field will significantly enhance your ability to grasp the nuances tested in these professional-level exams.
- A strong desire to achieve professional certification in data engineering and a commitment to dedicating time for intensive practice and review. This course assumes you have already acquired foundational knowledge and are now seeking to validate and solidify it for certification.

Skills Covered / Tools Used (Assessed)
- Data Modeling and Design: Assessing your ability to design efficient data models for various use cases, including relational databases, data warehouses (star/snowflake schemas), data lakes, and NoSQL databases, considering performance, scalability, and cost.
- Data Ingestion and Transformation: Evaluating your knowledge of different methods for ingesting data (batch, streaming) and transforming it (ETL/ELT pipelines), including concepts of data pipelines, change data capture, and data quality checks.
- Data Storage Solutions: Testing your understanding of appropriate data storage choices for different scenarios, such as object storage (e.g., S3, ADLS, GCS), transactional databases, analytical databases (e.g., Redshift, Synapse, BigQuery), and NoSQL databases (e.g., DynamoDB, Cosmos DB, Firestore).
- Big Data Technologies: Examining your competency with big data processing frameworks and services like Apache Spark, Hadoop ecosystem components, Apache Kafka for real-time data streaming, or their managed cloud equivalents (e.g., EMR, Dataproc, HDInsight, Kinesis, Pub/Sub).
- Orchestration and Automation: Assessing your grasp of tools and concepts for scheduling, monitoring, and managing complex data workflows and pipelines, including Apache Airflow, cloud-native workflow orchestrators (e.g., AWS Step Functions, Azure Data Factory, Google Cloud Composer).
- Data Governance, Security, and Compliance: Probing your awareness of best practices for securing data at rest and in transit, implementing access controls, managing data lineage, ensuring data quality, and adhering to regulatory compliance standards (e.g., GDPR, HIPAA).
- Performance Optimization: Challenging your ability to identify and resolve performance bottlenecks in data pipelines, queries, and storage systems, applying techniques such as indexing, partitioning, caching, and query optimization.
- Troubleshooting and Monitoring: Testing your skills in diagnosing issues within data engineering systems, understanding logging and monitoring frameworks, and implementing alerts to maintain data pipeline health and reliability.
- Cloud-Specific Data Services: Implicitly covering the application of various cloud provider-specific data services that are common in professional data engineering roles, ensuring readiness for a multi-cloud or cloud-agnostic certification.
-
