Editorial Policy
Published and last reviewed: September 2, 2026
Free ER Diagram publishes database design guides, SQL examples, and documentation that support the site's working diagram tool. This policy explains how that material is selected, checked, attributed, and corrected. The purpose of every indexed page is to help a reader solve a distinct database modeling or documentation problem.
How Topics Are Selected
Topics begin with a task a developer can perform: translating CREATE TABLE statements into a diagram, identifying relationship cardinality, reviewing a schema for integrity problems, or comparing diagram output formats. We avoid creating several pages that answer the same question with slightly different wording. A new article should provide a different workflow, a complete worked schema, or a technical comparison that is useful without requiring an advertisement or purchase.
How Technical Material Is Produced
Guides are written for this site and paired with concrete SQL definitions, relationship explanations, or review checklists. Schema examples are designed around stated business rules instead of being copied from database dumps or public article feeds. Before publication, examples are checked for consistent table and column names, valid parent-child references, explicit primary keys, and relationship descriptions that agree with the SQL.
Claims about the tool are checked against the current application source. Because the parser is deliberately focused on CREATE TABLE syntax, articles should distinguish between a feature the parser recognizes and a broader feature supported by a database engine. The parser coverage page records this boundary and gives readers a verification checklist.
Review Standards
- Examples must contain enough context to explain why tables and constraints exist.
- SQL snippets must use internally consistent identifiers and reference existing parent keys.
- Security or integrity caveats must be stated when an ER diagram cannot enforce them.
- Articles must disclose practical limitations instead of describing generated output as automatically authoritative.
- External facts and third-party product capabilities should be verified against primary documentation when they materially affect the advice.
Originality, Automation, And Commercial Influence
Free ER Diagram does not republish scraped articles, syndicated feeds, or lightly rewritten third-party pages. The site does not accept paid guest posts, paid links, or affiliate placements in editorial material. Software may assist with drafting or quality checks, but a maintainer reviews the final page for accuracy, usefulness, duplication, and consistency with the working product before publication. Automatically generated pages are not published without that review.
Updates And Corrections
Pages display a review or update date when technical material changes. Minor typography changes do not require a new date; changes to code examples, product behavior, compatibility, or recommendations do. Readers can report an error through the contact page. A correction is checked against the application source or relevant database documentation and then applied to the affected page rather than hidden in a separate response.
Publisher Transparency
Free ER Diagram is maintained as a public browser-based developer tool. Its purpose, data handling, and project contact are described on the About page and Privacy Policy. The application's implementation and revision history can also be inspected in the public source repository.
