Oracle Database is the backbone of enterprise applications worldwide — from banking systems to telecommunications platforms. But traditional Oracle design tools are expensive, complex, and built for individual DBAs rather than collaborative development teams. ER Flow brings a modern, visual approach to Oracle schema design that works for the whole team.
Model Oracle tables with the full range of column types: VARCHAR2, NUMBER, DATE, TIMESTAMP WITH TIME ZONE, CLOB, BLOB, RAW, and XMLTYPE. Define primary keys, create indexes, and draw foreign key relationships on a visual canvas that renders your Oracle schema as a navigable ER diagram. ER Flow understands Oracle conventions and generates syntactically correct DDL.
ER Flow's real-time collaboration means your Oracle DBA and application developers work on the same schema simultaneously — no more emailing .pdf diagrams or syncing changes through a shared drive. Connect your AI assistant via MCP Server to accelerate schema scaffolding and generate migration scripts that evolve your Oracle database safely.
Design tables with VARCHAR2, NUMBER(p,s), DATE, TIMESTAMP, CLOB, BLOB, and RAW. ER Flow generates Oracle-compatible DDL for every column definition.
Connect Cursor, Windsurf, or Claude Code to ER Flow and scaffold Oracle schemas from natural language. The AI reads your current schema and creates tables, sequences, and relationships.
DBAs, architects, and developers design the Oracle schema together in real-time. CRDT-powered sync eliminates version conflicts and keeps everyone aligned.
Generate Oracle-compatible CREATE TABLE and ALTER TABLE scripts from schema diffs. Deploy schema changes to Oracle with precision and a full audit trail.
Export DDL from Oracle SQL Developer or Data Pump and paste it into ER Flow's SQL import. Visualize your entire Oracle schema instantly.
Add new tables for upcoming features. Use Oracle column types, define constraints, and draw relationships on the canvas.
Invite your DBA team and application architects. Review the schema design in real-time and capture decisions before writing migration scripts.
Checkpoint the current schema, make changes, and generate a precise SQL diff migration. Deploy to Oracle staging and production with confidence.
