“Data pipeline” and “Extract, Transform, Load” (ETL) are common phrases encountered in just about every data integration. But what’s the difference?

From airline tickets going through the roof during holiday seasons to Uber and other ride-sharing services charging higher prices in rush hour, we have become accustomed to paying different prices for the same services. Traditionally, dynamic pricing was a tool reserved for industry giants like Amazon because of its implementation complexity and price tag.

Marketing data integration is the process of combining marketing data from different sources to create a unified and consistent view. If you’re running marketing campaigns on multiple platforms—Facebook, Instagram, TikTok, email—you need marketing data integration. Why?

For any system where there is communication between components or with the outside world, there is an increase in possible software cybersecurity threats.

Working with complex nested data objects can be difficult, especially when accessing a specific property or subset of data in a complex data structure. This post will look at complex data objects, what they are, and an easier way of managing those complex data objects by using complex types.

Exceptions are unintended events that take place when a program is being executed or during its runtime causing disruptions to the program's overall logic. In Ruby, a program is enclosed between the begin and end blocks and a rescue block is used to tell what types of exceptions are to be handled.

The ActionController::UnpermittedParameters error occurs when a parameter that has been passed is not permitted in a create, an update, or a user-defined action. In older versions of Rails, information about the unpermitted keys was provided in the logs only when an unpermitted parameter was found in a request. This did not provide enough information for the developers to understand which controller and action received the unpermitted parameters.

Once a customer is ready to purchase, the final frontier lies ahead: the payment process. Because online transactions already come fraught with a learning curve, companies must use extensive payment gateway testing to deliver frictionless payment experiences.

Where other aspects of software may enjoy the leeway to go live while minor problems are ironed out, payment gateways cannot afford anything less than perfect reliability.
