What protocol is used in JDBC connection?

The JDBC Thin driver allows a direct connection to the database by providing an implementation of TCP/IP that emulates Oracle Net and TTC (the wire protocol used by OCI) on top of Java sockets. Both of these protocols are lightweight implementation versions of their counterparts on the server.

How does JDBC connect to database?

The steps for connecting to a database with JDBC are as follows:

1. Install or locate the database you want to access.
2. Include the JDBC library.
3. Ensure the JDBC driver you need is on your classpath.
4. Use the JDBC library to obtain a connection to the database.
5. Use the connection to issue SQL commands.

Which method is used to establish the connection with database?

The getConnection() method of DriverManager class is used to establish connection with the database.

Which method can be used for establishing a connection to a JDBC data source?

Create Connection Object − Finally, code a call to the DriverManager object’s getConnection( ) method to establish actual database connection.

What protocol is used between server and database?

The Named Pipes protocol is a high-level interface providing interprocess communications between clients and database servers using distributed applications.

How does the JDBC framework 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.

How is JDBC used to connect database at the back end?

When you are connecting to the back-end Oracle database, use the JDBC driver. When connecting to the repository in the back-end Oracle database, provide a URL to locate the database. Use the Thin JDBC driver to connect to the back-end Oracle database.

How does JDBC handle the data types of Java and database?

The JDBC driver converts the Java data type to the appropriate JDBC type, before sending it to the database. It uses a default mapping for most data types. For example, a Java int is converted to an SQL INTEGER. JDBC 3.0 has enhanced support for BLOB, CLOB, ARRAY, and REF data types.

How does database connection work?

A database connection is a facility in computer science that allows client software to talk to database server software, whether on the same machine or not. A connection is required to send commands and receive answers, usually in the form of a result set. Connections are a key concept in data-centric programming.

Which methods are required to load a database driver in JDBC *?

Explanation: There are two ways to load a database driver in JDBC:

• By using the registerDriver() Method: To access the database through a Java application, we must register the installed driver in our program. We can do this with the registerDriver() method that belongs to the DriverManager class.
• By using the Class.

Which protocol establishes connection between client and server?

In client-server protocols, it is the client which establishes the connection. Opening a connection in HTTP means initiating a connection in the underlying transport layer, usually this is TCP. With TCP the default port, for an HTTP server on a computer, is port 80. Other ports can also be used, like 8000 or 8080.

What is a database protocol?

A network protocol is a set of rules that govern how data is transferred between applications and, in this context, between a client and a database server. The rules of a protocol are implemented in a network driver .
