SQL Professional Editor vs DB RelationalAlgebra

SQL Editor Pro is a focused SQL workspace for iPhone—built so you can author, refine, and ship queries without a laptop. Open scripts from Files, edit with syntax highlighting and line numbers, switch SQL dialects, then call an AI copilot when you want deeper analysis or fixes. Who it’s for Developers, analysts, DBAs, and students who need a fast, readable editor plus intelligent help—not another heavyweight IDE. Editor & files • Import .sql and plain-text scripts via the system document picker • Edit with syntax-highlighted, monospace-friendly editing and line numbers • Choose dialect-aware context: Generic, MySQL, PostgreSQL, SQLite, or SQL Server • Save and share SQL using familiar iOS export and share flows AI tools (requires internet) • Deep Analysis — structured review across syntax, logic, performance, and suggested fixes • Fix My SQL — corrected SQL you can apply back into the editor • Performance Optimizer — practical tuning angles for heavier workloads • Explain & Risk Check — plain-language behavior notes and safer-run reminders Power productivity • SQL Formatter — clean up messy scripts for readability • Templates — start faster from curated patterns for common tasks • History Restore — snapshots when you format, apply AI fixes, import templates, or capture manually • Power Tools — duplicate/manual snapshots and export a packaged text bundle of your editor SQL plus history Plans SQL Editor Pro includes free starter usage for premium actions (AI, Save, Share), then Pro unlocks unlimited access via In‑App Purchase (subscriptions and a lifetime option where configured). Editing core functionality remains available on device; AI features need a network connection. Privacy-conscious design • No third‑party advertising or analytics SDKs bundled for tracking • Cloud AI sends only what you submit when you run AI features (your SQL and related prompt context) over encrypted HTTPS to our AI routing provider; see Privacy Policy for details • Local preferences, optional history snapshots, and usage counters may be stored on-device using standard iOS storage mechanisms Important AI output can be wrong—independent review is required before running SQL against real systems.

A native iPad and iPhone app that converts a SQL query typed, pasted, or imported from a .sql file into relational algebra, tuple relational calculus and domain relational calculus. Each notation gets a step by step derivation, a final oneline formula, and an interactive diagram an operator tree for the algebra, a quantifier scope tree for the calculus and a fourth view stacks all three against the same query. Whatever SQL asks for that a notation cannot express exactly is reported rather than quietly approximated.
