sqlite

https://www.sqlite.org/index.html

SQLite is a C-language library that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine. SQLite is the most used database engine in the world.

Python/DjangoREST also supports sqlite.

There is also a JDBC driver for it (Github source code) and it's JPA compliant.

A JDBC sample URL for a DB stored in sample.db file is

jdbc:sqlite:sample.db

   1 apt install sqlite3
   2 sqlite3 test.db

   1 -- SQL steps
   2 CREATE TABLE IF NOT EXISTS PushNotificationsTable (push text);
   3 insert into PushNotificationsTable values('aaa');
   4 select * from PushNotificationsTable;
   5 .help
   6 .databases
   7 .tables
   8 .dbinfo
   9 .output out.txt
  10 .dump PushNotificationsTable
  11 .quit
