PostgreSQL vs SQLite

Difference Between PostgreSQL vs SQLite

In PostgreSQL vs SQLite, SQLite is defined as an open-source relational database management system that is a file-based system popular for its reliability, portability, strong performance, and lightweight on nature that supports low-memory environment also and it provides several features like transactional serverless that supports transaction when any system crashes or power outage goes down. PostgreSQL is another open-source relational database management system used to handle multiple tasks simultaneously and also supports ACID (atomicity, consistency, integrity, and durability) theorem. PostgreSQL is not so popular compared to SQLite and it is not used widely for storing the data.

Key differences of PostgreSQL vs SQLite

Below are the key differences between PostgreSQL and SQLite

One of the major differences between both the system is in-memory capabilities. The SQLite system supports in-memory capabilities that help to perform the data operations efficiently whereas in the PostgreSQL system there is no such functionality of in-memory capability.

The other difference between the PostgreSQL system and the SQLite system is partitioning methods. The SQLite system does not support any type of partitioning methods. On the other hand, the PostgreSQL system supports various types of partitioning methods like list, range, and hash.

One of the major differences between both the system is the use of servers. The SQLite system does not need any kind of server to run thus it is known as serverless. On the other hand, the PostgreSQL system require the server to run and support multiple operating systems like FreeBSD, Windows, Solaris, and many more. The SQLite system does not support XML format. The PostgreSQL system supports XML format.

The other major difference between both the system is authentication and security. The PostgreSQL system provides various advanced security features and there are several in-built configurations. On the other hand, in the SQLite system, there is no authentication system used as the files of a database can be accessed by everyone.

Another difference between these two systems is user management. In the PostgreSQL system, multiple users can access the system with proper authorization. The SQLite system does not support access to multiple users as the user management functionality is not present in the SQLite system. The features offered by the PostgreSQL function are advanced in nature while on the other hand, the SQLite system provides basic features to the user.

The other key difference between the SQLite system and the PostgreSQL system is the replication strategy. The PostgreSQL system supports master-slave replication, streaming, cascading, and synchronous replications. On the other hand, in the SQLite system, there is no replication strategy follow that creates a limitation for this type of system. The compatibility with data types is another major factor in comparing both the system. The PostgreSQL system is mostly compatible with all the data types that make the system popular while on other hand, the SQLite system does not support advanced data types and supports only a few data types like Integer, Real, Blob, Text and Null.

The other major difference between the system is the use of the database. The PostgreSQL system provides the functionality to handle the complex database without having any type of restrictions. On the other hand, the SQLite system is a small application and used to handle a simple database system. The major use of the PostgreSQL system is when the two functions of data integrity and data reliability are the points of concern. On the other hand, the SQLite system is preferred when there is a requirement to use the database is standalone applications.

Conclusion

The SQLite and PostgreSQL database system is an open-source RDBMS system that supports the ACID theorem and helps to manage the data. The SQLite is preferred in the case of IoT and embedded applications where the PostgreSQL system is preferred for the complex database systems. The selection of the system is based on the use case and requirements of the application.
