Data Warehousing Concepts is a focused practice tool for analytics engineers, BI developers, and students learning how enterprise data warehouses are designed and operated. This app drills the specific patterns that show up in real warehouse work: choosing between star and snowflake schemas, modeling slowly changing dimensions (SCD Type 1/2/3), reasoning about fact-vs-dimension grain, deciding when an OLAP cube beats a flat table, and untangling ETL versus ELT trade-offs in modern stacks like Snowflake, BigQuery, and Redshift. What you will practice - Dimensional modeling: fact tables, conformed dimensions, surrogate keys, role-playing dimensions - ETL/ELT pipelines: staging layers, incremental loads, CDC, idempotency, late-arriving facts - OLAP operations: roll-up, drill-down, slice, dice, pivot, MOLAP vs ROLAP - Common pitfalls: chasm and fan traps, junk dimensions, additive vs semi-additive measures, grain mismatches - Advanced concepts: data vault, lakehouse architecture, columnar storage, partitioning, materialized views How you study - 160 multiple-choice questions across 4 difficulty tiers - Every question includes a detailed explanation of why the right answer is right and why the distractors are wrong - FSRS spaced-repetition schedules the next review based on your recall strength - Weak-point heatmap shows which topic areas need more work - Daily challenge keeps a steady review cadence - Mock exam mode times you against the full question pool - Fully offline after install, no account, no tracking, no in-app purchases Who this is for Data analysts moving into engineering, BI developers preparing for technical interviews, students taking a database systems course, and self-learners filling gaps before stepping into a warehouse role.
