1. 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。
2. MongoDB：
MongoDB 是一个开源的面向文档的数据库，用于大容量数据存储。它属于 NoSQL 数据库的分类。 NoSQL 工具意味着它不使用通常的行和列。 MongoDB 使用 BSON(文档存储格式)，它是 JSON 文档的二进制样式。
SQLite 和 MongoDB 的区别：
| S.NO. | SQLITE | MONGODB |
|---|---|---|
| 1. | Developed by D. Richard Hipp on August 2000. | Developed By MongoDB, Inc on 2009. |
| 2. | It is widely used in-process RDBMS. | It is one of the most popular document stores available both as fully managed cloud service and for deployment on self-managed infrastructure. |
| 3. | The primary database model for SQLite is Relational DBMS. | The primary database model for MongoDB is Document store. |
| 4. | It has no Secondary database models. | It has Document store as Secondary database models. |
| 5. | SQLite is developed only in C language. | MongoDB is developed only in C++ language. |
| 6. | SQLite does not require a server to run. Hence, it is serverless. | Server operating systems for MongoDB are Linux, OS X, Solaris and Windows. |
| 7. | It does not support Server-side scripting. | It has Javascript for Server-side scripts. |
| 8. | It supports SQL query language only. | It supports JSON query language along with SQL. |
| 9. | It does not support any replication methods. | It support only one replication methods – Master-master replication. |
| 10. | It does not support any Partitioning methods. | In MongoDB, partitioning can be done by Sharding. |
| 11. | SQLite does not supports Map Reduce method. | MongoDB supports Map Reduce method. |
| 12. | SQLite provides the concept of Referential Integrity and have Foreign keys. | MongoDB does not provides the concept of Referential Integrity. Hence, no Foreign Keys. |
