Why this course

SQL is the lingua franca of data. This program takes learners from writing correct queries to designing high-performance data platforms and tuning queries across different engines. It's structured so non-engineers can become power users and engineers can gain DBA-level performance skills.

Audience

Analysts, data engineers, DBAs, backend developers, and architects who work with relational and analytic databases.

Outcomes

Write complex analytics queries, tune high-volume workloads, design warehouses, and operate distributed SQL engines.

Prerequisites

Beginner track requires no SQL experience. Advanced tracks assume familiarity with basic SELECT/JOIN concepts.

Progression Levels

Structured certificates at four levels — each with exams, labs, and a capstone aligned to real-world domains.

Level 1 — Beginner

SQL basics: SELECT, FILTER, JOINs, GROUP BY, simple aggregations, basic window functions and CTEs.

  • Labs: Sales & orders dataset queries
  • Quiz: 40-question multiple choice

Level 2 — Advanced

Advanced window functions, analytic patterns, complex joins, subqueries, performance-aware SQL, and materialized views.

  • Labs: Cohort analysis, LAG/LEAD patterns
  • Assessment: Practical query assignment

Level 3 — Expert

Execution plans, indexing strategies, partitions, transactions, concurrency, stored procedures, and query refactoring.

  • Labs: Optimize queries on 50M+ rows, index design
  • Assessment: Performance tuning project

Level 4 — Super Advanced

Distributed SQL architectures, cost-based optimization internals, query federation, columnar engines (ClickHouse), OLAP design, and cloud-specific tuning (Snowflake/BigQuery).

  • Labs: Data warehouse design, partition strategies, materialized views at scale
  • Assessment: Capstone — design & deliver a performant data mart

Curriculum Highlights — Topics & Modules

Below are representative modules. The full syllabus maps modules to levels and engines (Postgres, Snowflake, BigQuery, ClickHouse, Databricks SQL).

Analytical SQL & BI Patterns

  • Window functions, running totals, moving averages
  • Time-series aggregation, time bucketing, fiscal calendars
  • CTEs for pipeline clarity and modular queries
  • Query patterns for cohort, retention and funnel analysis

Data Engineering SQL

  • ETL vs ELT patterns, incremental loads, CDC basics
  • Materialized views, partitions, clustering, and micro-partitions
  • Scheduling, orchestration with Airflow / dbt integration
  • Data quality checks and testable SQL patterns

Performance & Tuning

  • Indexes (B-tree, GIN, BRIN), predicate pushdown, and statistics
  • Execution plans, cardinality estimation, and common pitfalls
  • Batching, pagination, and avoiding anti-patterns (SELECT *)
  • Concurrency control, isolation levels, and locking

Distributed & Cloud SQL

  • Snowflake micro-partitioning, BigQuery slots & cost controls
  • Databricks SQL optimizations and adaptive query execution
  • ClickHouse columnar engine, MergeTree tables, and OLAP patterns
  • Federated queries, external tables, and cross-engine considerations

Security & Governance

  • Roles & privileges, row-level security, and data access controls
  • Data lineage, auditing, and SQL-based masking techniques
  • Cost governance and query throttling strategies

Tooling & Observability

  • EXPLAIN/EXPLAIN ANALYZE, async profilers, and query logs
  • Monitoring slow queries, tracking cost and usage metrics
  • dbt models, lineage visualization, and CI for SQL tests

Hands-on Labs & Domain Case Studies

Real datasets and domain-specific labs to apply SQL skills. Each lab includes test datasets, starter queries, and a checklist for optimization and production readiness.

Banking — Transaction Analytics & AML

Aggregate transactions, compute rolling customer risk scores, detect anomalies, and build efficient alert queries for AML workflows (includes time-windowed joins and stateful aggregations).

Retail — Funnels, CLV & Promotion Analysis

Sessionization, funnel conversion rates, cohort CLV, and measuring promo uplift with proper control/baseline SQL patterns.

Energy — Time-Series Aggregation

Handle high-volume time-series data, compute load curves, resample irregular telemetry, and optimize windowed queries for performance.

Healthcare — Claims & Population Metrics

Process EHR/claims-like datasets, build patient cohorts, and compute population-level metrics while preserving privacy via masking and aggregation.

Labs run on local Postgres and cloud sandboxes (Snowflake/BigQuery/Databricks/ClickHouse) — participants receive datasets and guided notebooks.

Supported Engines & Engine-specific Tips

We teach engine-agnostic SQL principles and deep dives into popular platforms so you can transfer skills across systems.

PostgreSQL / MySQL / SQL Server

Indexes, explain plans, stored procedures, window functions, and OLTP tuning. Includes platform-specific tips (VACUUM, autovacuum, statistics).

Snowflake & BigQuery

Micro-partitions, clustering keys (Snowflake), slot management (BigQuery), cost control, and best practices for ELT workflows and materialized views.

Databricks SQL & ClickHouse

Databricks adaptive execution, cache strategies, and ClickHouse MergeTree engines, indexing, and OLAP optimizations for extremely high-throughput queries.
