What is the architecture of JDBC?

The JDBC architecture consists of two-tier and three-tier processing models to access a database. They are as described below: Two-tier model: A java application communicates directly to the data source. The JDBC driver enables the communication between the application and the data source.

What is JDBC in detail?

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 provides methods to query and update data in a database, and is oriented toward relational databases.

What are the components of the JDBC architecture?

JDBC includes four components:

• The JDBC API. The JDBC API gives access of programming data from the Java.
• JDBC Driver Manager. The JDBC DriverManager is the class in JDBC API.
• JDBC Test Suite.
• JDBC-ODBC Bridge.
• Connection.
• Class.forName(String driver)
• DriverManager.
• getConnection(String url, String userName, String password)

What is JDBC write its features?

Following are the new features of JDBC: Makes JDBC calls: While using JDBC Java applications can make JDBC calls these calls submit SQL statements to the driver which in turn accesses the data from the database. To communicate with database. JDBC provides support for advanced datatypes such as BLOB, CLOB etc.

What are two type and three type JDBC architecture?

For the two-tier model and the three-tier model, JDBC has two main layers: JDBC API (an application-to-JDBC Manager connection), JDBC Driver API (this supports the JDBC Manager-to-Driver Connection). The JDBC driver manager and database-specific drivers provide the possibility to connect to heterogeneous databases.

What are the steps to use JDBC API?

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 JPA and JDBC?

JDBC is a low level standard for interaction with databases. JPA is higher level standard for the same purpose. JPA allows you to use an object model in your application which can make your life much easier. JDBC allows you to do more things with the Database directly, but it requires more attention.

What is JDBC full form?

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 are the four main components of the JDBC API?

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.

Which is the main component of JDBC API?

JDBC API: It is a Java abstraction which enables applications to communicate with relational databases. It provides two main packages namely, java. sql and javax. sql.

What is JDBC API and when do we use it?

The Java Database Connectivity (JDBC) API provides universal data access from the Java programming language. Using the JDBC API, you can access virtually any data source, from relational databases to spreadsheets and flat files. The JDBC API is comprised of two packages: java. sql.

Which of the following is correct about Statement class of JDBC?

Explanation. Statement encapsulates an SQL statement which is passed to the database to be parsed, compiled, planned and executed. Q 10 – Which of the following is correct about ResultSet class of JDBC? A – ResultSet holds data retrieved from a database after you execute an SQL query using Statement objects.

How is the JDBC architecture used in Java?

Below Figure is a representative sketch of the JDBC architecture. This can be used in Java applications,applets, servlets or any other program where Java codes used. Java codes only interact with theJDBC Application-Program Interface (API).

What are the components of the JDBC API?

Common JDBC Components The JDBC API provides the following interfaces and classes − DriverManager − This class manages a list of database drivers. Matches connection requests from the java application with the proper database driver using communication sub protocol.

How is JDBC used to establish a database connection?

Matches connection requests from the java application with the proper database driver using communication sub protocol. The first driver that recognizes a certain subprotocol under JDBC will be used to establish a database Connection. Driver − This interface handles the communications with the database server.

What’s the difference between JDBC 1 and 2?

JDBC Specification: Different version of JDBC has differentspecification as under. JDBC 1.0 – it provides basic functionality ofJDBC. JDBC 2.0 – it provides JDBC API (JDBC 2.0Core API and JDBC 2.0 Optional Package API). JDBC 3.0 – it provides classes and interfaces intwo packages (java.sql and javax.sql).
