Download Couchbase 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 Couchbase, 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 Couchbase are listed in the section below.

Couchbase is a distributed NoSQL cloud database that combines the flexibility of JSON document storage with the power of SQL-like querying via N1QL. It is designed for mission-critical applications requiring high availability, elastic scalability, and low-latency data access. Couchbase supports key-value, document, full-text search, analytics, and eventing workloads in a single platform.
Couchbase JDBC Driver Details
- Required File(s): couchbase-jdbc-driver-xxx.jar
- Java Driver Class: com.couchbase.jdbc.CouchbaseDriver
- JDBC URL: jdbc:couchbase://{HOST}:{PORT}
- Website: Couchbase
The JDBC driver connects to the Couchbase Analytics Service on port 8095 (or the Query Service on port 8093 for N1QL). Authentication uses a Couchbase username and password. Ensure the Analytics or Query service is enabled on your cluster before connecting.
DbSchema and Couchbase
DbSchema connects to Couchbase via its JDBC driver, allowing visualization of bucket and collection schemas, N1QL query authoring in the SQL editor, and interactive browsing of JSON document collections through the data explorer.

Explore Couchbase Visually with DbSchema
Once the JDBC driver is configured, DbSchema connects to your Couchbase 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 Couchbase 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 Couchbase 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 Couchbase 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 Couchbase 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 Couchbase 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 Couchbase schema. Share it with your team or embed it in your project wiki — no extra tooling required.
