PDE Study Strategy

1) Build a Solid Data Fundamentals Base

Review data modeling concepts, normalization/denormalization, and schema design.
Study ETL vs. ELT patterns and when each is best applied.
Understand batch vs. streaming architectures, trade-offs, and practical use cases.

2) Master Google Cloud Data Services

Gain hands-on experience with:
- Dataflow → stream & batch pipelines
- Pub/Sub → event-driven messaging
- BigQuery → analytics and warehousing
- Dataproc → Spark/Hadoop clusters
Learn storage decisions (Cloud Storage, Spanner, Bigtable, Firestore, Cloud SQL).
Compare cost models for different services in large-scale pipelines.

3) Emphasize Operational Excellence

Practice monitoring & logging with Cloud Monitoring and Logging.
Set up alerts for pipeline health and latency.
Implement security & governance: IAM roles, encryption (CMEK/KMS), DLP policies, VPC Service Controls.

4) Practice with Real-World Scenarios

Build end-to-end data pipelines from ingestion → processing → storage → analytics.
Design for reliability, fault tolerance, scalability, and cost-efficiency.
Explore hybrid/multi-cloud architecture considerations.

5) Mock Exams and Deep Dives

Take PDE practice tests to evaluate readiness.
Review detailed explanations of answers to understand trade-offs.
Deep dive into weak areas (e.g., streaming design, ML integration).
