JDBC full form Java Database Connectivity. Java Database Connectivity (JDBC) is an application programming interface (API) for the programming language Java, which defines how a client may access a database. JDBC enables java application to connect with database and perform data operation like insert update, delete, search and more.

Why JDBC came into existence ?
As previously told JDBC is an advancement for ODBC, ODBC being platform dependent had a lot of drawbacks. ODBC API was written in C,C++, Python, Core Java and as we know above languages (except Java and some part of Python )are platform dependent . Therefore to remove dependence, JDBC was developed by database vendor which consisted of classes and interfaces written in Java - geeksforgeeks
JDBC (Java Database Connectivity) allows multiple implementations to exist
JDBC connections support creating and executing statements and statements such as SQL's CREATE, INSERT, UPDATE and DELETE, or they may be query statements such as SELECT. Additionally, stored procedures may be invoked through a JDBC connection.
JDBC represents statements using one of the following classes:
Statement – the statement is sent to the database server each and every time.
PreparedStatement – the statement is cached and then the execution path is pre-determined on the database server allowing it to be executed multiple times in an efficient manner.
CallableStatement – used for executing stored procedures on the database.
Update statements such as INSERT, UPDATE and DELETE return an update count that indicates how many rows were affected in the database. These statements do not return any other information.

The Most common tasks used in JDBC assignment help or connect java project with jdbc connectivity as below.
Creating a connection to a database.
Creating SQL statements.
Executing SQL or MySQL queries in the database.
Viewing & Modifying the resulting records.
The JDBC API provides a number of interfaces and classes that represent a connection to the database, provide facilities for sending SQL queries to a database and help Java developer process the results of relational database interactions.Java can be used to write different types of executables, such as −
Java Applications with JDBC
Java Applets with JDBC
Java Servlets with JDBC
Java ServerPages (JSPs) with JDBC
Enterprise JavaBeans (EJBs) with JDBC
All of these different executables are able to use a JDBC driver to access a database, and take advantage of the stored data.
JDBC provides the same capabilities as ODBC, allowing Java programs to contain database-independent code.
