• Log in with an Oracle account (create one if necessary).
• After logging in, the download will start automatically.
• Save the file (OracleXE) once the download is complete.

Step 3: Extract the Files

• Go to the Downloads folder and locate the downloaded zip file.
• Right-click and extract the files.
• Navigate to the extracted folder (disk1) and find setup.exe.

Step 4: Installation Process

  • Accept the license agreement.
  • Choose the default installation path (C:\oraclexe) or customize it.
  • Set and confirm the password for the database.
  • Click "Install" and wait for the installation to complete.

Step 5: Finish Installation

• Once installed, a shortcut will appear on the desktop.

  • Change the port to 8080 and apply the changes.

Step 6: Accessing the Database
