Download Oracle 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 Oracle, 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 Oracle are listed in the section below.
Download the Oracle JDBC Driver
Oracle Database is the industry-leading enterprise RDBMS, widely used in banking, healthcare, and government sectors. It supports advanced features like partitioning, PL/SQL stored procedures, RAC clustering, and pluggable databases (PDB/CDB).
Oracle JDBC Driver Details
- Required File(s): ojdbc15.jar (For Java 1.5), ojdbc16.jar (For Java 1.6)
- Java Driver Class: oracle.jdbc.OracleDriver
- URL ( connect via SID ): jdbc:oracle:thin:@HOST[:PORT]:DB
- URL ( connect via service name ): jdbc:oracle:thin:@//HOST[:PORT]/DB
- Website: Oracle
The driver archive is a zip file. Extract it and load the .jar files using DbSchema's Driver Manager.
Thin Driver vs Oracle Client
The thin driver (oracle.jdbc.OracleDriver) does not require an Oracle client installation and works out of the box.
Connect via SID (jdbc:oracle:thin:@host:port:SID) or service name (jdbc:oracle:thin:@//host:port/service).
For Autonomous Database on Oracle Cloud, download the wallet and use the ojdbc-full.jar bundle which includes the required TLS certificates.
DbSchema and Oracle
DbSchema renders Oracle's multi-schema environments as tabbed diagrams, making it easy to navigate between large schema objects like tables, views, packages, and sequences. The Schema Synchronization feature generates Oracle-compatible DDL including sequence grants and constraint syntax.

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