JDBC URL
a JDBC URL has a variety of formats. They have three parts in common. * Protocl. It is the protocol JDBC. * The name of the product / vendor, such as MySQL, or Postgres. * Database-specific connection details, typically contains the location and the name of the database. A location can be localhost or an IP address / port or a domain name. The location is optional. The database name is required. Colons separate the three parts. ``` jdbc:postgres://localhost:5432/zoo ```
