What’s on the CompTIA DataSys+ cheat sheet
- Database Fundamentals (24%) — the relational model and keys, SQL command categories (DDL/DML/DCL/TCL), join types, normalization (1NF–3NF), and ACID.
- Database Deployment (16%) — SQL vs. NoSQL models, on-prem vs. cloud (IaaS/PaaS/DBaaS), scripting and infrastructure as code, stored procedures, and OLTP vs. OLAP.
- Database Management & Maintenance (25%) — the single heaviest domain — clustered vs. non-clustered indexing, execution plans, locking and deadlocks, monitoring, jobs, and patching.
- Data & Database Security (23%) — the CIA triad, RBAC and least privilege, encryption at rest (TDE) and in transit (TLS), masking, auditing, and SQL-injection defense.
- Business Continuity (12%) — full/differential/incremental backups, RPO and RTO, RAID levels, replication, failover, and disaster recovery.
How to use it in your final week
- Front-load the two heaviest domains — Database Management & Maintenance (25%) and Database Fundamentals (24%) together are nearly half the exam. Drill indexing, execution plans, SQL command categories, joins, and the normal forms until they're reflexive.
- Rehearse the classic traps from the sheet: DELETE (DML, rollback-able) vs. TRUNCATE vs. DROP (both DDL), clustered vs. non-clustered indexes, and full vs. differential vs. incremental backups.
- Do at least one timed 90-minute run of 90 questions so the clock and the performance-based questions feel routine — budget extra seconds for the PBQs that make you write or fix SQL.
- Skim the sheet the morning of your exam for a last pass on the memory hooks: 700 passing scaled score, ACID, the CIA triad, least-privilege RBAC, and RPO/RTO driving backup frequency and recovery design.

CompTIA DataSys+ cheat sheet FAQ
Yes — the CompTIA DataSys+ cheat sheet downloads as a PDF with no sign-up and no payment. It's part of Career Employer's free DataSys+ toolkit, sitting alongside the practice test, study guide, and flashcards so your whole DS0-001 review stays in one place.
It condenses the highest-yield DS0-001 facts into a quick reference organized by the five official domains: Database Fundamentals, Database Deployment, Database Management and Maintenance, Data and Database Security, and Business Continuity. You get SQL command categories, join types, normal forms, ACID, indexing, RBAC, encryption, RAID, and RPO/RTO on a scannable sheet.
No — DataSys+ reports a scaled score of 700 on a 100 to 900 scale as pass or fail, and roughly a quarter of the exam is performance-based questions that ask you to write SQL and complete hands-on tasks. The sheet locks in the facts, but you still need lab reps and timed practice questions to be ready for the PBQs.
It's built from CompTIA's current DS0-001 exam objectives, the version launched in 2023, and we re-check it against CompTIA's published objectives on a regular cadence. Every domain weight on the sheet mirrors the official blueprint.
