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 HBase, so you never have to write low-level socket code. Drivers are typically distributed by the database vendor or as open-source projects.
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 HBase are listed in the section below.
Apache HBase is a distributed, column-family NoSQL database modeled after Google Bigtable, running on top of HDFS in a Hadoop cluster. It provides random read/write access to billions of rows and petabytes of data, making it ideal for sparse, wide-column data like user activity logs and event streams.
DbSchema can connect to HBase using the Phoenix JDBC driver. This driver requires Phoenix to be deployed on HBase cluster. Please check this link for details.
The driver archive is a zip file. Extract it and load the .jar files using DbSchema's Driver Manager.
DbSchema connects to HBase via the Phoenix JDBC driver (which adds SQL semantics on top of HBase) and renders Phoenix tables and secondary indexes as a visual schema. Use the SQL Editor to run standard SQL queries against HBase data through the Phoenix layer.

Once the JDBC driver is configured, DbSchema connects to your HBase 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.
Reverse-engineer your HBase 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.
Compose HBase 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.
Browse HBase 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.
Compare your HBase 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.
Write and execute HBase 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.
Generate a static HTML site documenting every table, column, type, index, and relationship in your HBase schema. Share it with your team or embed it in your project wiki — no extra tooling required.
