Errors happen all the time in the software world. It might be an invalid user input or an external system that is not responding, or it’s a simple programming error. In all these situations, the errors occur at runtime and the application needs to handle them. Otherwise, it crashes and can’t process further requests. Java provides a powerful mechanism which allows you to handle the exceptional event where it occurred or in one of the higher methods in the call stack.

An exception is a known type of error. An unhandled exception occurs when the application code does not properly handle exceptions. For example, When you try to open a file on disk, it is a common problem for the file to not exist. The.NET Framework will then throw a FileNotFoundException. This is a simple example of a potential known problem that is accounted for within the code. Let’s take this code sample below.

Performance testing scripts need to go through authentication in order to access target services with the right authorization. They also need to validate that the authentication servers are able to handle the target load. OpenID Connect(OIDC) has become a popular authentication and authorization protocol for securing web applications. This article will present the OIDC protocol and how to implement a JMeter script to performance test it.

Experts predict that the global enterprise data management market will grow at a compound annual growth rate of 12.1% until 2030. Your organization’s database management system (DBMS) stores all the enterprise data you need for software applications, systems, and IT environments, helping you make smarter data-driven business decisions. Here are the key things to know about database schema design.

When choosing a modern database, one of the biggest decisions is picking a relational (SQL) or non-relational (NoSQL) data structure. Both systems offer unique advantages and cater to different needs, making the choice between them crucial for optimal data management.
