JDBC ArchitectureThe JDBC API supports both two-tier and three-tier processing models for database access. Figure 1: Two-tier Architecture for Data Access. In the two-tier model, a Java applet or application talks directly to the data source. This requires a JDBC driver that can communicate ...
Figure 1: JDBC 3.0 Connection Pooling Architecture When an application makes a connection by callingDataSource.getConnection()on aPoolingVendorDataSourceobject, thePoolingVendorDataSourceobject performs a lookup in the connection cache to determine if aPooledConnectionobject is available. If one is avail...
The JDBC DriverManager class defines objects which can connect Java applications to a JDBC driver. DriverManager is considered the backbone of JDBC architecture. DriverManager class manages the JDBC drivers that are installed on the system. Its getConnection() method is used to establish a connection ...
which is a set of classes/interfaces that implements these interfaces(such as java.sql.Driver) for a particular database system. Following the JDBC architecture, a Java database application uses the DriverManager class to get the java.sql.Connection...
JDBC’s detail architecture The JDBC API does most of the things through the DriverManager class(java.sql.DriverManager). What is DriverManager? It is a connection factory class.
