DBST 670 is the three-credit capstone of the Database Systems Technology program at the University of Maryland Global Campus.
UMGC requires 30 credits of program coursework, including all core courses, before enrollment. It describes an introduction to the knowledge, skills and tools needed to administer operational database systems.
The catalog says the course provides conceptual and operational tools for analyzing and resolving problems such as performance, recovery, design and technical issues, and covers the tools used in administration. It draws together the program, so earlier course habits show up here.

What DBST 670 Covers
| Area (from UMGC) | What it means in practice |
|---|---|
| Administering operational databases | Keeping a live system healthy, available and secure |
| Performance problems | Diagnosing slow queries, locking and resource limits |
| Recovery problems | Backups, logs and restoring after failure |
| Design problems | Spotting schema and indexing issues that cause trouble |
| Technical issues | Troubleshooting configuration and system behavior |
| Administration tools | Using tools to monitor, tune and manage |
Key Concepts Explained
Diagnosing a Performance Problem
Work from symptom to cause: what is slow, since when, and what changed. Check the query and plan, then indexes and statistics, then locking, then hardware limits.
Illustrative scenario: A nightly report that took ten minutes now takes an hour. The data has grown, the plan switched from an index lookup to a full scan after statistics were stale, and refreshing statistics returned the plan to normal. A good write-up shows each step of the reasoning.
Recovery Planning
A recovery plan states how much data loss and downtime are acceptable, which backups are taken and how often, and how restoration is tested. An untested backup is only a hope.
Change Control
Administrators record what they change, why and how to reverse it. This habit turns troubleshooting from guesswork into an auditable process.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Scenario analysis | Structured diagnosis | State symptoms, hypotheses, checks and conclusion |
| Recovery plan | Backup and restore thinking | Define recovery goals before choosing methods |
| Tool-based tasks | Using management tools | Record settings and results with screenshots or logs |
| Capstone report | Integrating program knowledge | Link each recommendation to evidence and to earlier course concepts |
Where Students Get Stuck
- Jumping to fixes. Diagnose before changing anything.
- Ignoring recovery goals. Methods only make sense against stated objectives.
- Thin evidence. Show logs, plans or timings to support claims.
- Forgetting earlier courses. Concurrency, design and security concepts all appear.
Planning Your Work
| Stage | Do this | Output |
|---|---|---|
| Start | Review notes from core courses | One-page concept summary |
| Analysis | Work scenarios with a fixed template | Symptom, cause, fix, check |
| Recovery | Draft a plan with objectives | Backup schedule and test steps |
| Final | Integrate and proofread | Clear report |
A fixed template for every scenario (symptom, evidence, likely causes, test, fix, verification) keeps your answers consistent and complete.
A Worked Recovery Planning Example
| Question | Illustrative answer |
|---|---|
| How much data loss is acceptable? | No more than 15 minutes of transactions |
| How long can the system be down? | Up to one hour |
| What backups support this? | Weekly full, daily differential, frequent log backups |
| How is it tested? | Monthly restore to a test server with row counts checked |
The figures here are placeholders to show the structure, not recommendations. Your scenario will set its own objectives, and the key is that every method you choose is tied to a stated goal.
When writing a capstone-style analysis, link each recommendation to a concept from earlier courses where you can. For example, a locking problem connects to concurrency control, a slow join to physical design, and an access problem to database security. This shows the integration that a capstone is designed to test.
Final Checks Before Submitting
Reread each scenario answer and ask four questions. Did I state the symptom clearly? Did I show evidence for the cause? Did I tie the fix to a stated goal? Did I say how I would verify it worked?
Answers that cover all four read as professional administration rather than guesswork, and they are easy for an instructor to follow and credit.
Study Tips for DBST 670
- Revise transactions, indexing and security before the first assignment.
- Keep a troubleshooting checklist you can reuse.
- Explain in plain language what each tool measures.
- Check your syllabus for the required tools and formats.
