1.德比：
Derby 是一个用Java实现的功能齐全的开源关系数据库管理系统 (RDBMS)，顾名思义，它是由 Apache Software Foundations 开发的。它基于Java、JDBC 和 SQL 标准。 Derby 易于安装、部署和使用。它要么嵌入到Java应用程序中，要么用作数据库服务器。
2. SQLite：
SQLite 是一个提供关系数据库管理系统 (RDBMS) 的软件库。它由 D. Richard Hipp 于 2000 年 8 月设计。SQLite 的设计目标是允许程序在不安装数据库管理系统 (DBMS) 或不需要数据库管理员的情况下运行。 SQLite 中的 lite 意味着在设置、数据库管理和所需资源方面的轻量级。
Derby 和 SQLite 的区别：
| SR.NO | Derby | SQLite |
|---|---|---|
| 1 | It is developed by Apache Software Foundation in 1997 | It is developed By D. Richard Hipp in 2000. |
| 2 | It is written in Java language. | It is written in C language. |
| 3 | The primary database model for Derby is Relational DBMS. | The primary database model for SQLite is Relational DBMS. |
| 4 | Server operating systems for Derby are Windows, macOs, Linux, Unix, BSD and z/OS. | SQLite does not require a server to run. Hence, it is serverless. |

| 6 | It support Master-Slave Replication methods. | It does not support any replication methods. |
| 7 | APIs and other access methods used by Derby is JDBC. | APIs and other access methods used by SQLite are ADO.NET, JDBC and ODBC. |
| 8 | It support only Java programming language. | It support C, C#, C++, D, Delphi, Java, JavaScript, Lua, MatLab, Objective-C, Perl, PHP, PL/SQL, Python, R, Ruby, Scala, etc. |
| 9 | It provide XML support. | It do not provide XML support. |
