Java JDBC stands for “Java Database Connectivity,” which is a standard Java API (Application Programming Interface) for accessing and manipulating databases. The JDBC API enables Java programs to connect to a wide range of relational databases, such as Oracle, MySQL, Microsoft SQL Server, and PostgreSQL, among others.

Using JDBC, Java developers can create applications that interact with databases, perform queries, insert, update, and delete data. The JDBC API is built on top of the SQL language and provides a set of interfaces and classes that abstract the underlying database and make it easy to perform database operations.

Here are the basic steps to use JDBC in a Java program:

  1. Load the JDBC driver for the database you want to connect to.
  2. Create a connection to the database using the JDBC driver.
  3. Create a statement object to execute SQL queries.
  4. Execute SQL queries and retrieve data.
  5. Close the statement and connection objects.

JDBC provides a rich set of APIs for handling database connections, transactions, and errors. It also supports advanced features such as batch updates, prepared statements, and stored procedures.

Overall, JDBC is an essential tool for Java developers who want to create powerful, data-driven applications that can interact with relational databases.

Why Should We Use JDBC:

JDBC is an essential tool for Java developers who need to access and manipulate data stored in relational databases. Here are some of the key reasons why you should use JDBC:

  1. Standardized API: JDBC provides a standardized API that can be used with a wide variety of relational databases, making it easier for Java developers to write portable code that works with multiple databases.
  2. High Performance: JDBC provides high performance by allowing database connections to be reused, and by supporting prepared statements and stored procedures.
  3. Secure: JDBC provides secure access to databases, as it supports authentication and encryption mechanisms to protect sensitive data.
  4. Scalable: JDBC provides scalable database access, as it supports connection pooling, which allows multiple clients to share a single database connection, reducing overhead and increasing performance.
  5. Rich set of features: JDBC provides a rich set of features, including transaction management, batch updates, and scrollable result sets, that enable Java developers to create powerful, data-driven applications.
  6. Integration with Java EE: JDBC is integrated with Java EE, making it easy to use in enterprise applications that require database access.

Overall, JDBC is a mature and reliable technology that provides a standard API for accessing relational databases from Java applications. By using JDBC, Java developers can write database-driven applications quickly and easily, without having to worry about the intricacies of low-level database programming.

What is API:

API stands for “Application Programming Interface.” An API is a set of protocols, tools, and standards that allows different software applications to communicate with each other. In other words, an API defines how two different software systems should interact with each other.

APIs are used to provide a standard way for different software applications to exchange data and information with each other, regardless of the programming language, platform, or operating system used to build them. APIs can be used for a variety of purposes, such as accessing data from a remote server, controlling hardware devices, or integrating different software systems.

In software development, APIs are typically created by developers and made available to other developers, who can then use them to build their own applications. APIs can be public, meaning that they are available for anyone to use, or private, meaning that they are only available to certain users or groups.

APIs are essential in modern software development, as they allow developers to build more complex and powerful applications by combining different software components and services. APIs are widely used in web development, mobile app development, and cloud computing, among other areas of software development.
