Exploring More Complex Trigger Scenarios

Now that you know how to create simple triggers from our previous article, Introducing Database Triggers, let’s move on to more complex scenarios.

By Rafael Victória-Pereira

As you probably realized by now, a trigger can be used for many different tasks. Updating a certain value each time a record is somehow created or changed is just a very small part of what you can do with a trigger. Let me take you on an exploration of a few scenarios where a properly crafted trigger can be a simple solution to a complex problem. Instead of vague and insipid scenarios, we’ll return to our fictional UMADB database and its environment to provide something you can actually relate to. So, just to quickly get you back “into character”: we work for ACME University’s IT department, and we’ve been overhauling the database in order to open it to all the non-IBM i applications that need its data.

More Programming in Python

Python has a bunch of built-in functions, and it also comes with a whole list of modules and classes that can be used to construct your programs. I introduce programming in Python here. In most cases, you will start by building functions, and those functions may, or may not, be combined into modules at some point. We’ll take it a step at a time.

Functions

For RPG programmers, at least the more “modern” ones (whoever they are), monolithic code is an anathema. It’s hard to read, hard to debug, and hard to share. And if you do decide to share or copy it, then if you tweak the “mother” of the others, you need to update the others as well. Most RPG and COBOL programmers I know abandoned that technique about the time that Prince changed his name to ... well, whatever it was changed to. What replaced the monolithic coding style? Well, subroutines were the first step, and…

Five Reasons Why Node Is the Solution your Company Needs Right Now

There is certainly no shortage of options when it comes to choosing a path to modernization. But two common approaches – re-writing the application code and migrating to a packaged application – can be riskier than sticking with the legacy applications. Knowing this, it’s no wonder why the path to modern applications is a long and bumpy one for so many businesses.

But there is some good news in the way of a development language called Node.js. You may have heard some buzz around it, as it’s currently in use at some of the world’s top businesses, including Walmart, PayPal, Uber, Netflix, and Google, to name a few. Profound Logic's solutions and services, including RPG-to-Node code transformation, make Node a perfect solution to address your current business challenges. Here are five reasons why we’ve adopted Node for legacy modernization and think you should, too!

Here’s the harsh reality: cybersecurity pros have to get their jobs right every single day, while an attacker only has to succeed once to do incredible damage.

Whether that’s thousands of exposed records, millions of dollars in fines and legal fees, or diminished share value, it’s easy to judge organizations that fall victim. IBM i enjoys an enviable reputation for security, but no system is impervious to mistakes.

Join this webinar to learn about the biggest errors made when securing a Power Systems server.

This knowledge is critical for ensuring integrity of your application data and preventing you from becoming the next Equifax. It’s also essential for complying with all formal regulations, including SOX, PCI, GDPR, and HIPAA
