Download Informix JDBC Driver
What Is a JDBC Driver?
A JDBC driver is a Java library file (.jar) that enables Java applications — including DbSchema — to communicate with a database over a standard API. The driver translates generic JDBC calls into the network protocol understood by Informix, so you never have to write low-level socket code. Drivers are typically distributed by the database vendor or as open-source projects.
Understanding the JDBC URL
Every JDBC driver identifies the target database through a connection URL. The URL encodes the hostname, port, database name, and any driver-specific parameters as a single string. The exact syntax varies per driver — the details for Informix are listed in the section below.

IBM Informix is a high-performance embedded and enterprise database used in retail point-of-sale systems, financial institutions, and time-series data management. It is known for its JSON/BSON support, time-series extensions (TimeSeries), and very low memory footprint.

The driver archive is a zip file. Extract it and load the .jar files using DbSchema's Driver Manager.
DbSchema and IBM Informix
DbSchema connects to Informix using the IBM JDBC driver and renders table hierarchies, fragment strategies, and smart large objects in the ER diagram. Use the Schema Synchronization feature to generate Informix-compatible DDL including FRAGMENT BY ROUND ROBIN and EXTENT SIZE parameters.

Explore Informix Visually with DbSchema
Once the JDBC driver is configured, DbSchema connects to your Informix database and gives you a full graphical workbench — no command-line required. Available as a free Community Edition and a full-featured PRO Edition. No registration needed to get started.
Interactive ER Diagrams
Reverse-engineer your Informix schema into a drag-and-drop ER diagram. Arrange tables visually, add new columns, define foreign keys, and let DbSchema generate the DDL — all without writing SQL by hand.
Visual Query Builder
Compose Informix queries by clicking on tables and columns — no SQL knowledge required. Add joins, filters, groupings, and aggregations through a point-and-click interface, then copy the generated SQL or run it directly against the live database.
Relational Data Explorer
Browse Informix table data and follow foreign key relationships across tables in a single view. Edit cells inline, filter rows, and paginate through large datasets — all without leaving the explorer.
Schema Synchronization
Compare your Informix schema across development, staging, and production environments. DbSchema generates the exact ALTER statements needed to close the gap and lets you review every change before executing — reducing the risk of unintended schema drift.
SQL Editor
Write and execute Informix queries in the integrated SQL editor with schema-aware autocomplete, syntax highlighting, and instant result display. Run scripts, inspect execution plans, and export results to CSV or JSON from a single interface.
HTML Schema Documentation
Generate a static HTML site documenting every table, column, type, index, and relationship in your Informix schema. Share it with your team or embed it in your project wiki — no extra tooling required.
