A database driver is
a computer program that implements a protocol (ODBC or JDBC) for a database connection
. The driver works like an adaptor which connects a generic interface to a specific database vendor implementation. … To connect with individual databases, JDBC requires drivers for each specific database type.
What is a driver in SQL?
DBMS-based drivers are used with data sources such as Oracle or SQL Server that provide a stand-alone database engine for the driver to use. These drivers
access the physical data through
the stand-alone engine; that is, they submit SQL statements to and retrieve results from the engine.
What are the different examples of a database drivers?
- 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.
- Type 5: highly-functional drivers with superior performance.
What is mysql database driver?
Driver class: The driver class for the mysql database is
com. mysql. jdbc.
What are ODBC and JDBC?
ODBC is
an SQL-based Application Programming Interface (API)
created by Microsoft that is used by Windows software applications to access databases via SQL. JDBC is an SQL-based API created by Sun Microsystems to enable Java applications to use SQL for database access.
What are the 4 types of JDBC drivers?
- Type-1 driver or JDBC-ODBC bridge driver.
- Type-2 driver or Native-API driver.
- Type-3 driver or Network Protocol driver.
- Type-4 driver or Thin driver.
What are 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.
Why do we need database drivers?
“Similar to connecting a printer to a computer by using a printer driver, a DBMS (database management system) needs a
database driver that enables a database connection in other systems
. The driver works like an adaptor which connects a generic interface to a specific database vendor implementation.
How many ways can you register a driver?
JdbcOdbcDriver(); 23) How many ways to register a driver? Explanation: There are
four ways
to register a driver: 1.
Which JDBC driver is efficient?
Which driver is efficient and always preferable for using JDBC applications?
Type 4 Driver
is a Database-Protocol Driver(Pure Java Driver). Its implementation allows the conversion of JDBC calls directly into a vendor-specific database protocol.
Why do we need JDBC drivers?
To connect with individual databases, JDBC (the Java Database Connectivity API) requires drivers for each database. The JDBC driver
gives out the connection to the database and implements the protocol for transferring the query and result between client and database
.

Should I use ODBC or JDBC?
For Java applications it is not recommended to use ODBC because performance will be down due to internal conversion and applications will become platform Dependent. For Java application
it is highly recommended to use JDBC
because there we no performance & platform dependent problem.
What is the purpose of ODBC?
ODBC
makes it possible to access data from any application
, regardless of which database management system (DBMS) is handling the data. ODBC is based on the Call-Level Interface [CLI] specifications from X/Open and ISO/IEC for database APIs and uses Structured Query Language [SQL] as its database access language.
What is ODBC example?
ODBC stands for
Oracle Database Connectivity
. It is an API which is used to access different databases. The OFBC driver uses the Open Database connectivity interface provided by Microsoft to communicate with the databases. It is independent of Databases and platforms and operating systems.
