Design and Manage Daffodil DB Databases with DbSchema

Build a clearer workflow for Daffodil DB: reverse engineer existing schemas into interactive ER diagrams, model changes visually, and generate reviewed SQL scripts before deployment.

DbSchema is built for visual modeling, schema documentation, and deployment. Keep an offline model in Git, collaborate across teams, and publish documentation that developers, analysts, and stakeholders can navigate in minutes.

Visual Schema Tools for a Pure-Java SQL Database

Daffodil DB is a pure-Java SQL database that supports both an embedded mode — running inside the same JVM as the host application — and a network server mode accessible via JDBC from remote clients. It was designed for Java environments requiring a portable, dependency-light relational store. DbSchema connects to Daffodil DB in either mode, renders the schema visually, and provides SQL editing and documentation tools for teams maintaining Daffodil DB applications.

Connect to Daffodil DB in Embedded or Network Mode

DbSchema uses the Daffodil DB JDBC driver and supports both deployment modes through their respective connection URLs. Once connected, tables, views, and their column definitions appear in the diagram canvas, providing a visual overview of the database structure.

Run SQL Queries in the SQL Editor

DbSchema's SQL editor accepts Daffodil DB's SQL dialect, executes queries against the connected instance, and presents results in an inline table. Use it to validate query logic, investigate data anomalies, and test DDL changes before applying them to a production Daffodil DB instance.

Document the Daffodil DB Schema

For Daffodil DB applications that have grown organically without formal documentation, DbSchema's documentation generator produces a structured HTML report with table listings, column types, constraints, and embedded relationship diagrams — useful for audits, developer onboarding, and migration planning.

Connecting DbSchema to Daffodil DB

For the Daffodil DB network server, use jdbc:daffodilDB_net://host:3456/dbname, where 3456 is the default server port. For embedded access, use jdbc:daffodilDB_embedded:dbname. Download the Daffodil DB JDBC driver from the Daffodil Software website and register it in DbSchema's driver manager. In embedded mode, only one JVM can hold an exclusive lock on the database at a time — stop the host application before connecting from DbSchema to avoid a file lock conflict.

Why DbSchema for Daffodil DB

  • Connect to Daffodil DB in both embedded and network server deployment modes.
  • Visualize table schemas and relationships for applications with undocumented databases.
  • Run and iterate on SQL queries in an interactive editor without a separate CLI.
  • Generate HTML documentation reports for compliance reviews and team handovers.
  • Design schema changes and review generated DDL before applying them to the database.
