1. MySQL：
MySQL 是一种基于结构化查询语言 (SQL) 的开源关系数据库管理系统 (RDBMS)。它由oracle 公司开发和管理，于1995 年5 月23 日首次发布。它被广泛应用于许多小型和大型工业应用程序，能够处理大量数据。
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)的情况下运行或需要数据库管理员。 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。
MySQL 和 SQLite 的区别：
| S.NO. | MySQL | SQLite |
|---|---|---|
| 1. | Developed by Oracle on May 1995. | Developed By D. Richard Hipp on August 2000. |
| 2. | MySQL is developed in C and C++ languages. | SQLite is developed only in C language. |
| 3. | MySQL requires a database server for its functioning. Hence, it follows client/server architecture. | SQLite does not require a server to run. Hence, it is serverless. |
| 4. | It can handle multiple connections simultaneously. | It can handle only one connection at a time. |
| 5. | It is highly scalable and can handle a large volume of data very efficiently. | It can handle only small set of data if the volume of data increased its performance degrades. |
| 6. | It requires large space in the memory for its functioning (approx 600 Mb). | It requires only some KBs of space as it is very lightweight approx (250Kb-300Kb). |
| 7. | MySQL supports multiple user environment. | SQLite does not support multiple user environment. |
| 8. | It also supports XML format. | It does not supports XML format. |
