Difference between Oracle and Derby

1. Oracle :
Oracle is a relational database management system (RDBMS). It was developed by Oracle Corporation in 1980. It is the first database designed for grid computing that provides the most flexible and cost-effective way to manage information and application. It runs on major platforms like Windows, Unix, Linux, and macOS. It is a relational database in which data is accessed by user through application or query language called SQL.

2. Derby :
Derby is a open source relational database management system. It is developed by Apache Software Foundation in 1997. It is written and implemented completely in the Java programming language. The primary database model of Derby is Relational DBMS. All OS with a Java VM are server operating system. It provides users fine grained access rights according to SQL-standard and with a small-footprint standards-based database engine that can be tightly embedded into any Java based solution.
