Introduction
H2 database and SQLite are indeed the two most popular light weight relational database system. Both the database application are open source and available free of cost for commercial and personal use. Both the system read and writes to a database file in the system on which it runs.
Usually these database system are used for desktop and mobile application. Both the database system have many things in common but there are some differences as well which a programmer should keep in mind before choosing any database system.
let’s see some of the key differences between these two database systems.
Key Differences
H2 database is developed in Java where as SQLite is developed in C language.
H2 database can be accessed over the network via TCP protocol but SQLite database can not. SQLite can be used only on the system where it is running.
As far as security is concerned SQLite does not offer any security and does not have a User Management support, also it writes to a file which can be accessed by any User and allows to make changes with out any authentication.
On the other hand H2 database have User Management support and authenticate the user before establishing the connections. Also it offer 128 bit AES encryption to the database files which make it hard for the User to make changes directly.
H2 database is highly scalable and can handle large volume of data efficiently whereas SQLite tends to lose its performance with increase in the volume of data.
The most powerful feature that H2 db offers is that it can execute the Java functions, that means you can write your own Java functions and store it in the database for later use. SQLite does not offer such features.
Conclusion
Overall we could say that H2 db offers so many features that makes it ideal database for a small and medium scale application.
