What is JDBC driver type?
Type 1: JDBC-ODBC bridge. Type 2: partial Java driver. Type 3: pure Java driver for database middleware. Type 4: pure Java driver for direct-to-database.
What is Type 3 JDBC driver?
The JDBC Type 3 driver is a network-protocol, all-Java driver. This style of driver translates JDBC calls into the middleware vendor’s protocol, which is then translated to a DBMS protocol by a middleware server. The middleware provides connectivity to many different databases.
Which driver is fast in JDBC?
JDBC Net pure Java driver
JDBC Net pure Java driver(Type 4) is the fastest driver because it converts the JDBC calls into vendor specific protocol calls and it directly interacts with the database.
What is JDBC and JDBC drivers?
A JDBC driver uses the JDBC™ (Java Database Connectivity) API developed by Sun Microsystems, now part of Oracle, that provides a standard way to access data using the Java™ programming language. … Using JDBC allows you to write one application that can send SQL statements to different data sources.
What is JDBC driver manager?
DriverManager manages the set of Java Database Connectivity (JDBC) drivers that are available for an application to use. … By passing a URL for a specific JDBC driver to the DriverManager, the application informs the DriverManager about which type of JDBC connection should be returned to the application.

Which driver is faster in Java?
In general its Type 4 driver is the fastest for localhost and remote connections, the Jaybird Type 2 ‘Embedded’ driver is usually the fastest overall as that will host the database server in the Java process, foregoing the overhead of the network or inter-process communication.

Which of the following driver converts the JDBC calls into database specific calls?
Native API driver converts JDBC calls into database-specific native libraries calls and these calls are directly understood by the database engine.
Which JDBC driver can be used in servlet and applet both?
4. Which JDBC driver Type(s) can be used in either applet or servlet code? Explanation: In a Type 3 driver, a three-tier approach is used to accessing databases.
Which one of these is limitation of type 4 driver in JDBC?
Cons: Not optimized for server operating system, so the driver can’t take advantage of operating system features. (The driver is optimized for the database and can take advantage of the database vendor’s functionality.) User needs a different driver for each different database.
What is a JDBC driver and how many JDBC drivers are available?

What is ODBC drivers?
An ODBC driver uses the Open Database Connectivity (ODBC) interface by Microsoft that allows applications to access data in database management systems (DBMS) using SQL as a standard for accessing the data. … ODBC permits maximum interoperability, which means a single application can access different DBMS.
How does a JDBC driver work?
The JDBC Driver is a set of classes that implement the JDBC interfaces to process JDBC calls and return result sets to a Java application. The database (or data store) stores the data retrieved by the application using the JDBC Driver. … A Connection object controls the connection to the database.
Which of the following about JDBC drivers is true?
Q 7 – Which of the following is correct about driver interface of JDBC? A – JDBC driver is an interface enabling a Java application to interact with a database. B – The JDBC driver gives out the connection to the database and implements the protocol for transferring the query and result between client and database.
Which type of driver provides JDBC access via one or more ODBC drivers?
Type one drivers provide JDBC access via one or more Open Database Connectivity (ODBC) drivers. ODBC, which predates JDBC, is widely used by developers to connect to databases in a non-Java environment.
