Step 1: Install Oracle SQL Developer

Before you can create a local database connection, you need to have Oracle SQL Developer installed on your computer. You can download the latest version of SQL Developer from the Oracle website. Follow the installation instructions provided by Oracle to install the software on your system.

Step 2: Launch Oracle SQL Developer

Once SQL Developer is installed, launch the application. You will see a welcome screen that allows you to connect to a database or open an existing connection.

Step 3: Create a New Connection

To create a new connection, click on the “New Connection” button on the welcome screen. This will open the “Create New Connection” dialog box.

Step 4: Choose the Database Type

In the “Create New Connection” dialog box, select “Oracle” as the database type. This will display the Oracle-specific connection details.

Step 5: Enter Connection Details

Enter the following details in the connection dialog box:

– Username: Enter the username for the local database.
– Password: Enter the password for the local database.
– Hostname: Enter the hostname of the local database. For a local connection, you can use “localhost” or “127.0.0.1”.

– SID/Service Name: Enter the SID or Service Name of the local database.

Step 6: Test the Connection

After entering the connection details, click the “Test Connection” button to verify that the connection to the local database is successful. If the connection is successful, you will see a message indicating that the connection was established.

Step 7: Save the Connection

If the connection test is successful, click the “OK” button to save the connection. The connection will now be available in the “Database” tree on the left side of the SQL Developer window.
