In today’s digital age, data has evolved from being a mere byproduct of business processes to becoming the cornerstone of strategic decision-making. Yet, for many organizations, unlocking the full potential of their data remains a significant challenge. Traditional data analytics models often create bottlenecks, relying heavily on overextended IT departments to provide insights, which delays decision-making and limits agility.

As digital transformation accelerates, the importance of specialized testing services has grown exponentially. While still relevant, traditional functional testing no longer suffices for businesses aiming to deliver robust, seamless applications that meet modern user demands. Specialized testing—spanning performance, cognitive, and UX domains—is now critical in ensuring digital ecosystems’ resilience, security, and usability.

In the previous part of this series, we discovered how to create persistent connections in Rack in theory, but now we'll put what we learned into practice. The web has two formalized specifications for communication over a persistent connection: server-sent events (SSEs) and WebSockets. WebSockets are widely used and highly popular, but SSEs are far less well-known. Let's explore them first.

Unit tests are essential for increasing the test coverage of a backend application, ensuring its reliability, functionality, and robustness. Jest has become one of the most popular solutions when unit testing in Node, due to its intuitive API, zero-configuration philosophy, and flexible approach to code transpilation. In this guide, you will learn more about Jest, explore its features, and see it in action through a complete example. Become a Jest unit testing expert!

PostgreSQL's EXPLAIN command is a powerful tool that provides insights into how a query will be executed. It helps developers and database administrators identify potential performance issues in their queries. In this blog, we will explore what EXPLAIN is, when to use it, how to interpret its output, and techniques for optimizing queries based on the insights it provides.

Web-based applications continue to be part of the modern connected experience, whether for banking, entertainment, health, or others.

Payment testing is undeniably challenging. Companies invest heavily in verifying end-to-end transaction success, but even the most skilled internal teams and sophisticated lab environments have their limits.

We are excited to introduce a new feature in Choreo that provides the ability to register and consume third-party services through connections. This feature empowers developers to seamlessly integrate external services such as Twillio, Salesforce, etc. with their Choreo applications, opening up a world of possibilities for creating more robust and versatile applications.
