Are you IGNOU MCA Student and want to Solution of This Question What is JDBC? Write and run a server program for online submission will solve this question for you.
Java Database Connectivity (JDBC) is a Java-based API that allows Java applications to interact with databases. It provides a standard way for Java applications to connect to and perform operations on relational databases.
Here’s a simplified example of a server program for online submission of an examination form for an IGNOU MCA 5th Semester course using JDBC. Please note that this is a basic example for educational purposes, and in a real-world scenario, you would need to implement security measures, error handling, and other best practices.
Assumptions for this example:
- You have a MySQL database named “examination_db” with a table named “exam_forms” containing columns:
- You have the MySQL JDBC driver JAR file (
mysql-connector-java-x.x.x.jar) in your classpath.
Please keep in mind that this is a basic example and lacks essential security measures like input validation and SQL injection prevention. In a real-world application, you’d need to implement these security measures to ensure the safety of user data and the system.
Additionally, the HTML form where students input their information (
examDate) would need to be created separately and linked to this servlet for processing.
