DERA — Understand Every Schema. Engineer Every Change.

DevSecOps & Release Engineering Foundation

DERA v0.1.0-alpha.3 — DevSecOps & Release Engineering Foundation

Understand Every Schema. Engineer Every Change.

DERA (Database Engineering & Reverse Analysis) is an open-source, deterministic database engineering and reverse-analysis platform under active development.

Version v0.1.0-alpha.3 is the planned Phase 3 milestone, focused on strengthening the project's continuous integration, security, documentation automation, engineering reliability, and release management infrastructure.

Development status: Alpha prerelease. This release is intended for contributors, maintainers, and early technical evaluation. It is not a production-ready stable release.

Highlights

1. Continuous Integration Foundation — Phase 3.1

• Main CI qualification architecture for pull requests and protected branches.
• Automated validation for implemented Python and frontend components.
• Consistent test execution and actionable failure reporting.
• Reproducible development and validation workflows.

2. Pull Request Governance — Phase 3.2

• Conventional Commit pull request title validation.
• Pull request readiness and metadata checks.
• Contributor-friendly validation feedback.
• Review and merge qualification safeguards.

3. Security & Supply-Chain Protection — Phase 3.3

• CodeQL static analysis configuration.
• Dependency vulnerability scanning and Dependabot integration.
• GitHub Actions permission hardening.
• Dependency and supply-chain security policies.

4. Documentation & Internationalization — Phase 3.4

• Documentation quality validation.
• Internal link and navigation checks.
• Multilingual README consistency verification.
• Support for the ten-language documentation system: English, Spanish, French, German, Portuguese, Italian, Japanese, Korean, Simplified Chinese, and Russian.

5. CI Performance & Artifact Management — Phase 3.5

• Dependency cache integrity and workflow efficiency improvements.
• Artifact naming and retention policies.
• Structured test reporting and diagnostics.
• Workflow concurrency and reliability management.

6. Release Qualification & Recovery — Phase 3.6

• Release candidate qualification procedures.
• Semantic versioning and release metadata validation.
• Artifact checksum verification.
• Release approval and publication safeguards.
• Rollback, recovery, and incident response documentation.

Security and Reliability

DERA's release engineering approach emphasizes deterministic validation, least-privilege execution, reproducibility, and auditable engineering processes.

Release publication must follow verified CI results, security checks, and maintainer approval.

Current Limitations

DERA remains in early development. The complete database inspection, reverse-engineering engine, visual engineering studio, diagnostics, and migration engineering functionality are not represented as production-ready in this alpha release.

Next Development Milestone

Phase 4 — Backend & Platform Infrastructure

The next development stage is planned to introduce the Python/FastAPI application foundation, API contracts, PostgreSQL platform persistence, authentication and authorization, background workers, and observability.

Current Development Status

DERA remains in its alpha foundation stage.

The work in this release concerns repository engineering and governance. It does not represent a completed database analysis product.

Database connectors, schema reverse engineering, ER diagrams, SQL analysis, migration planning, and other core platform features remain subject to implementation and verification in later milestones.

Previous Release

Scope of the architectural foundation:

• Modular monorepo design

• Application and package boundaries

• Python backend workspace foundation

• TypeScript frontend workspace foundation

• Shared engineering contracts

• Developer configuration and tooling

• Architecture documentation and module dependency rules

Engineering Architecture

DERA is designed around modular responsibilities:

Component | Intended responsibility -- | -- apps/web | Frontend application and visual engineering studio apps/api | Backend API and service orchestration packages/core | Deterministic schema engineering logic packages/connectors | Database-specific metadata inspection packages/contracts | Shared interfaces and data contracts tests | Automated engineering validation infrastructure | Local and future deployment infrastructure docs | Architecture and developer documentation

Individual components may still be incomplete or planned.

Technical Principles

DERA follows these principles:
