+## Overview
+
+This project demonstrates the use of sessionless transactions feature of Oracle Database using JDBC.
+
+The project is a web service that handles booking requests.
+
+## Building and testing
+
+Create a test user:
+
+~~~SQL
+CREATE USER test_user IDENTIFIED BY test_password;
+GRANT CREATE SESSION TO test_user;
+GRANT CREATE TABLE TO test_user;
+GRANT CREATE SEQUENCE TO test_user;
+GRANT DROP ANY TABLE TO test_user;
+GRANT UNLIMITED TABLESPACE TO test_user;
+~~~
+
+Please set the database URL as an environment variable before running the application.
+
+**Example:**
+~~~
+export TEST_DATABASE_URL=jdbc:oracle:thin:@localhost:5221:orcl
+~~~
+
+**Build and run endpoint tests:**
+~~~
+mvn install
+~~~
