What is the need of JDBC?
JDBC is a Java database API used for making connection between java applications with various databases. Basically, JDBC used for establishing stable database connection with the application API. To execute and process relational database queries (SQL or Oracle queries), multiple application can connect to different types of databases which supports both standard (SE) and enterprise (EE) edition of java.
Introduction to JDBC (Java Database Connectivity)
JDBC stands for Java Database Connectivity. JDBC is a Java API to connect and execute the query with the database. It is a specification from Sun Microsystems that provides a standard abstraction(API or Protocol) for Java applications to communicate with various databases. It provides the language with Java database connectivity standards. It is used to write programs required to access databases. JDBC, along with the database driver, can access databases and spreadsheets. The enterprise data stored in a relational database(RDB) can be accessed with the help of JDBC APIs.
