Content revision r2 Safe
Design Scalable Database Architectures
Poor database choices create expensive migrations, weak performance, and operational risk. This skill turns requirements and access patterns into practical schemas, technology choices, and migration plans.

Review the Skillstore skill "database-architect" from https://skillstore.io/skills/sickn33-database-architect.md and its manifest at https://skillstore.io/api/skills/sickn33-database-architect/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "database-architect". Choose a database for a multi-tenant commerce service with complex transactions and flexible product attributes.
Expected outcome:
- Recommendation: PostgreSQL for transactional integrity, mature indexing, and flexible reporting.
- Schema direction: normalized order tables with selective JSONB for variable product attributes.
- Validation: benchmark peak writes and confirm multi-region recovery objectives before commitment.
Using "database-architect". Plan a low-downtime migration from MySQL to PostgreSQL for a busy order platform.
Expected outcome:
- Preparation: inventory incompatible types, queries, extensions, and replication constraints.
- Transition: backfill historical data, stream changes, compare records, and run shadow reads.
- Cutover: pause risky writes, verify lag and checksums, switch traffic gradually, and preserve a tested rollback window.
Security Audit
Safev5 • 7/23/2026 Open versioned report
All ten static findings are false positives caused by ordinary database architecture language. The cited lines describe safety guidance, design patterns, constraints, and Mermaid outputs. No prompt injection, reconnaissance intent, executable behavior, or data exfiltration instructions were found in SKILL.md.

What You Can Build
Select a Greenfield Database
Compare storage technologies and define an initial schema from product requirements, workload patterns, team skills, and expected growth.
Plan a Platform Migration
Create phased migration, compatibility, validation, cutover, and rollback plans for changing engines or decomposing a shared database.
Design Regulated Data Storage
Map sensitive data, access controls, encryption, retention, audit logging, backups, and recovery requirements into a defensible architecture.
Try These Prompts
Choose a Database
Recommend a database for [application]. Expected scale is [volume], with [read/write pattern] and [consistency requirement]. Explain trade-offs and required clarifications.
Design a Schema
Design a schema for [domain] using [database]. Include entities, relationships, constraints, indexes, retention rules, and assumptions based on these access patterns: [patterns].
Plan a Safe Migration
Plan a migration from [source] to [target] for [data size and traffic]. Include phases, compatibility, validation, rollback triggers, backups, and cutover criteria.
Architect Global Scale
Design a multi-region data architecture for [system]. Address consistency, partitioning, replication, failover, RPO, RTO, cost, compliance, observability, and growth to [target scale].
Best Practices
- Provide concrete read, write, latency, consistency, availability, retention, and growth requirements.
- Separate current constraints from future targets so recommendations avoid premature complexity.
- Validate architecture decisions with representative data, load tests, migration rehearsals, recovery tests, and cost estimates.
Avoid
- Choosing a database from popularity alone without documenting workload fit and operational trade-offs.
- Treating generated schemas or capacity estimates as production-ready without benchmarks and environment-specific review.
- Executing irreversible migrations without backups, staged validation, rollback criteria, and accountable approval.
Frequently Asked Questions
Can this skill choose between SQL and NoSQL databases?
Yes. It compares data shape, access patterns, consistency, scale, team capability, cost, and operational complexity.
Can it create an entity-relationship diagram?
Yes. Request a Mermaid ERD and provide entities, relationships, cardinality, and key business rules.
Will it modify my database?
No by default. It recommends designs and migration steps, and it avoids execution unless explicitly requested and supported.
What information improves the recommendation?
Provide data volume, growth, query patterns, write rate, latency, consistency, availability, retention, compliance, budget, and team constraints.
Does it replace database testing or expert review?
No. Validate all recommendations with representative benchmarks, staging migrations, recovery tests, security review, and current vendor guidance.
Can it plan a zero-downtime migration?
It can propose phased backfills, change capture, compatibility controls, validation, cutover, and rollback. Actual feasibility depends on your environment.
