Bring Firebird's Hidden Schema Structure into the Open

DbSchema gives Firebird teams a design-first workflow: import the existing schema as an interactive ER diagram, refine it visually, and ship every change as a reviewed SQL script.

Built for visual modeling, schema documentation, and deployment, with an offline model you can keep in Git, team collaboration, and documentation that developers, analysts, and stakeholders can navigate in minutes.

Firebird is a mature open-source relational database with full ACID compliance, multi- generational concurrency control, stored procedures, triggers, and generators (sequences). It is embedded in many desktop and industrial applications — often without a dedicated DBA on-site. DbSchema connects to Firebird, renders the complete schema including stored procedure and trigger metadata in an ER diagram, and generates printable schema documentation that can accompany system deliveries or compliance audits.

Visualize Firebird Schemas Including Stored Objects

Firebird databases frequently contain stored procedures, triggers, and generators that are as central to the data model as the tables themselves. DbSchema renders the complete schema on the diagram canvas, letting you see table relationships, generator usage, and the overall structure of the database at a glance — not just the table list.

Write and Execute Firebird SQL

Firebird uses its own procedural SQL dialect — PSQL — for stored procedures and triggers, with syntax for control flow, exception handling, and generator access. DbSchema's SQL editor connects to Firebird and lets you query system tables, test stored procedure calls, and investigate data without switching to a separate tool such as FlameRobin or isql.

Generate Schema Documentation for Delivery and Audits

DbSchema auto-generates structured HTML documentation from the Firebird schema, covering tables, columns, constraints, stored procedures, triggers, and generators. Export this documentation as part of a system delivery package, or use it as a baseline for database audits — especially valuable for Firebird databases that have accumulated years of undocumented schema changes.

Set Up a Firebird Connection in DbSchema

Four steps take you from installer to a browsable Firebird diagram:

1. Install DbSchema, then grab Jaybird — the official Firebird JDBC driver — from the Firebird download page and add it through DbSchema's driver manager screen.
2. Start a new connection and supply the host and Firebird's default port 3050.
3. Use the JDBC URL jdbc:firebirdsql://host:3050//path/to/database.fdb — note the double slash before the absolute file path, which the Jaybird driver requires. For embedded Firebird, use jdbc:firebirdsql:embedded:/path/to/database.fdb with the embedded version of Jaybird instead.
4. If your database uses UTF-8 encoding, append ?encoding=UTF8 to the URL so character data is read and written correctly, then connect.

Once connected, DbSchema reads the full schema — including stored procedure and trigger metadata — and lays it out on the diagram canvas.

Why Use DbSchema with Firebird

• Render complete Firebird schemas including stored procedures, triggers, and generators
• Run Firebird PSQL queries and inspect system table metadata from the SQL editor
• Generate documentation for Firebird databases with no existing ERD
• Support system delivery and compliance audits with printable schema documentation
• Compare schema versions across Firebird database copies to track structural changes

Years of undocumented changes to a Firebird database stop being a mystery once the schema is on a diagram. Download DbSchema for free and generate documentation for your Firebird database today.
