Key Test Coverage Areas:
This practice test mirrors the real exam's structure and content. We've broken it down for easier preparation:
I. Data Modeling and Design (approx. 20 questions)
- Relational Databases: Understanding normalized forms (1NF, 2NF, 3NF, BCNF), database design principles, and relationship types. Think of it like building a well-organized house – each room (table) has a purpose and connects logically to others.
- Dimensional Modeling: Star schemas, snowflake schemas, and fact tables. This is all about creating clear, easily understandable data structures for analysis.
- NoSQL Databases: Understanding different types (document, key-value, graph), use cases, and tradeoffs. Sometimes a traditional house isn't enough; you might need a more flexible structure.
II. Data Warehousing and ETL Processes (approx. 25 questions)
- ETL Processes: Data extraction, transformation, and loading techniques. Imagine cleaning and organizing a messy attic before moving into a new home.
- Data Warehousing Architectures: Understanding the components and how they interact (data sources, staging areas, data warehouse). This is the blueprint for your data home – ensuring everything is in its place.
- Data Quality and Governance: Identifying and handling missing data, outliers, and inconsistencies. This involves quality control – making sure your data is accurate and reliable.
III. Cloud Data Engineering (approx. 25 questions)
- Cloud Platforms: Familiarity with at least one major cloud provider (e.g., AWS, Azure, GCP) and their data services. It's like choosing the right tools for building your house – each platform offers different strengths.
- Data Pipelines: Building and managing data pipelines using cloud-based tools. Think of this as the plumbing and electrical work, ensuring smooth data flow.
- Serverless Computing: Understanding and utilizing serverless architectures for data processing. This is like renting tools instead of owning them – flexible and scalable.
IV. Big Data Technologies (approx. 15 questions)
- Hadoop Ecosystem: Basic understanding of HDFS, MapReduce, Hive, Pig, Spark. This is like having a team of expert builders to handle large-scale projects.
- Data Streaming: Processing real-time data streams using technologies like Kafka or Kinesis. Imagine a live feed – your data is constantly updating.
V. Data Security and Compliance (approx. 15 questions)
- Data Security Best Practices: Implementing security measures to protect data at rest and in transit. Protecting your data is like securing your home with locks and alarms.
- Data Privacy Regulations: Familiarity with relevant regulations (e.g., GDPR, CCPA). Understanding the legal aspects of data handling is crucial.
