What is JDBC Slideshare?

Types of Drivers • A JDBC driver is a collection of Java classes that enables a programmer to connect a Java application to a certain database. • There are four types of JDBC drivers to connect with different types of databases.

What is JDBC in Java?

Java™ database connectivity (JDBC) is the JavaSoft specification of a standard application programming interface (API) that allows Java programs to access database management systems. The JDBC API consists of a set of interfaces and classes written in the Java programming language.

What is JDBC What are the characteristics of JDBC write a program to demonstrate how JDBC connection is established?

Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database. It is a Java-based data access technology used for Java database connectivity. It is part of the Java Standard Edition platform, from Oracle Corporation.

What is JDBC life cycle?

The life cycle for a servlet comprises of the following phases: DriverManager : for managing a list of database drivers. Driver : for communicating with the database. Connection : for interfacing with all the methods for connecting a database.

What is JDBC architecture?

Java Database Connectivity (JDBC) architecture is an API specifying interfaces for accessing relational databases. JDBC helps to connect to a database, send queries and updates to the database, and retrieve and process the results obtained from the database for queries.

What are different types of JDBC drivers?

There are 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 the JDBC API components in Java?

JDBC Core Components

• DriverManager. The DriverManager class keeps track of the available JDBC drivers and creates database connections for you.
• Driver. The Driver interface is primarily responsible for creating database connections.
• Connection.
• Statement.
• ResultSet.

What are the main steps in Java to make JDBC connectivity?

Fundamental Steps in JDBC

1. Import JDBC packages.
2. Load and register the JDBC driver.
3. Open a connection to the database.
4. Create a statement object to perform a query.
5. Execute the statement object and return a query resultset.
6. Process the resultset.
7. Close the resultset and statement objects.
8. Close the connection.

What is JDBC explain the advantages of JDBC?

It automatically creates the XML format of data from the database. It does not require the content to be converted. It provides full support to query and stored procedure. It provides support to both Synchronous and Asynchronous processing.

What is JDBC full form?

The Java Database Connectivity (JDBC) API provides universal data access from the Java programming language.

What is JDBC?  JDBC acronym of java Database connectivity; though Sun Microsystems claims that it is not the full form.  JDBC is a standard java API for independent database connection between a java program and wide range of relational database.  It is present in the “java.sql” package 4. Architecture of JDBC 5.

What is JDBC driver layer?

JDBC driver layer : Acts as an interface between a Java applications and a database. This layer contains a driver , such as a SQL server driver or an Oracle driver , which enables connectivity to a database. A driver sends the request of a Java application to the database.

What are the two layers of the JDBC architecture?

The JDBC architecture can be classified into two layers :\r JDBC application layer. JDBC driver layer. JDBC application layer : Signifies a Java application that uses the JDBC API to interact with the JDBC drivers. A JDBC driver is software that a Java application uses to access a database.

How are database transactions committed in JDBC applications?

The database transactions can be committed in two ways in the JDBC applications. Implicit : The Connection object uses the auto-commit mode to execute the SQL statements implicitly. The auto-commit mode specifies that each SQL statement in a transaction is committed automatically as soon as the execution of SQL statement completes.
