What are two types and three type JDBC architecture?

What are two types and three type JDBC architecture?

For the two-tier model and the three-tier model, JDBC has two main layers: JDBC API (an application-to-JDBC Manager connection), JDBC Driver API (this supports the JDBC Manager-to-Driver Connection). The JDBC driver manager and database-specific drivers provide the possibility to connect to heterogeneous databases.

• Connection.
• Class.forName(String driver)
• DriverManager.
• getConnection(String url, String userName, String password)
