Extension files allow you to extend the life of your database without having to completely re-engineer it.
By Joe Pluta
As business programmers, we spend most of our time working with the database, one way or another. Unless we're lucky enough to be in on the ground floor of a new installation of a modern package, chances are that database will require modifications to support changing business requirements. Even if it's an entirely custom application suite built specifically for your business model, the database probably has become a bit long in the tooth and needs to be updated to take advantage of newer features. Rafael Victoria-Pereira has written several excellent articles on database modernization, and I invite you to spend some time with them. Today, though, I'm going to talk about extending your existing IBM i database without modernizing it.
Today’s topic is normalization. If your database were a piece of dirty laundry, normalization would be a kind of wash-rinse-dry process. But in this case, shrinking wouldn’t be a problem.
By Rafael Victória-Pereira
Normalization, explained in the first TechTip of this series, is more than just a theoretical concept. It’s time to put it to work in your database.
Normalizing the Database
In this stage of the modernization process, it would be a good idea to take some time and revisit the database design, review the notes you took earlier, and have another look at the Entity Relationship Diagram you drafted. Then, follow the normalization process and update your logical database model’s tables to conform with the second normal form, at least. The following steps are involved in this stage:
Business users want new applications now. Market and regulatory pressures require faster application updates and delivery into production. Your IBM i developers may be approaching retirement, and you see no sure way to fill their positions with experienced developers. In addition, you may be caught between maintaining your existing applications and the uncertainty of moving to something new.
In this white paper, you’ll learn how to think of these issues as opportunities rather than problems. We’ll explore motivations to migrate or modernize, their risks and considerations you should be aware of before embarking on a (migration or modernization) project.
Lastly, we’ll discuss how modernizing IBM i applications with optimized business workflows, integration with other technologies and new mobile and web user interfaces will enable IT – and the business – to experience time added value and much more.
More than ever, there is a demand for IT to deliver innovation.
Your IBM i has been an essential part of your business operations for years. However, your organization may struggle to maintain the current system and implement new projects.
The thousands of customers we've worked with and surveyed state that expectations regarding the digital footprint and vision of the companyare not aligned with the current IT environment.
Have you been wondering about Node.js? Our free Node.js Webinar Series takes you from total beginner to creating a fully-functional IBM i Node.js business application.
Part 1 will teach you what Node.js is, why it's a great option for IBM i shops, and how to take advantage of the ecosystem surrounding Node.
In addition to background information, our Director of Product Development Scott Klement will demonstrate applications that take advantage of the Node Package Manager (npm).
Forms of ransomware has been around for over 30 years, and with more and more organizations suffering attacks each year, it continues to endure. What has made ransomware such a durable threat and what is the best way to combat it? In order to prevent ransomware, organizations must first understand how it works.
In this webinar, two experienced cybersecurity professionals go in-depth on the ransomware attack cycle, the need to protect every endpoint, and how to spot signs of infection before data is encrypted by malicious actors.
This webinar also reveals the current state of ransomware with 2021 Malware Survey results and provide effective security strategies for prevention.

With thousands of configuration settings and permissions to manage inside of AIX systems, it can seem overwhelming to ensure these systems maintain proper compliance. From users, password services, file, and directory permissions to how file systems are mounted and configured, there are countless elements to be on the lookout for. As you expand this into many different systems and start adding in Linux machines, which have the same compliance rules, and then add in your Windows machines with the same compliance rules, you quickly understand the tremendous scope you are managing, even in a small configuration with a few dozen systems.
