3. Oracle SQL Developer tool is a free database development tool provided by Oracle that allows users to connect to Oracle databases via a graphical interface for SQL development and management.
4. Connect using JDBC: To connect to an Oracle database in a Java application, Java Database Connectivity (JDBC) technology can be used. This involves downloading the Oracle JDBC driver and using relevant code in the application to establish the connection to the database.
5. To connect using ODBC: Utilize ODBC (Open Database Connectivity) technology to connect to an Oracle database in other development environments. Configure an ODBC data source in the system and use corresponding code to establish a connection with the database.

No matter which method you use, you need to provide the correct database connection information, including the username, password, hostname, port number, and service name. Ensure the accuracy and security of the connection information to successfully connect to the Oracle database and perform the necessary operations.
