Integrating DB2 with Web Applications

Integrating DB2 with web applications is essential for enabling dynamic and real-time interactions between web interfaces and your database. This tutorial will guide you through the process of integrating DB2 with web applications, allowing your users to access and manipulate data seamlessly through web interfaces.

Connecting DB2 with Web Applications

To integrate DB2 with web applications, you need to establish a connection between your web server and the DB2 database. Most web applications use programming languages like PHP, Python, or Java to interact with the database. Here's an example of connecting to DB2 using PHP:

Executing SQL Queries

After establishing the connection, you can execute SQL queries to retrieve or modify data in the DB2 database. Here's an example of executing a simple SELECT query using PHP:

Mistakes to Avoid

• Not securing database credentials in web application code.
• Not validating user inputs, leading to SQL injection vulnerabilities.
• Not handling database connections and resources properly, leading to performance issues.
