Modernizing SCOBOL Programs Part 2: Re-engineering using Blu Age

In Part 1 of this blog series, we discussed the benefits of modernizing SCOBOL requesters, and the challenge of handling programs with extensive business logic..

In this Part 2 installment, we will talk about how to approach these business logic embedded programs via re-engineering and the benefits of using a tool like Blu Age.

Re-engineering using framework

Re-engineering is a better approach to application modernization. Instead of selectively rewriting certain portions of the business logic to fit into a random mix of components (e.g. HTML, Java and JavaScript, etc.), re-engineering advocates redesigning the application from the ground up. By re-engineering, we mean applying a combination of human insight and automation power to migrating business logic (e.g. calculations, business rules)
to a modern technology framework.

Re-engineering wheels

A properly re-engineered application carries many benefits, including:

  • Maintainability
    Creation of code based on the new design blueprint using modern development methodology ensures there are readily available resources and tools for it to be maintained easily.
  • High performance
    Test tools are readily available in Open Source or commercial market to measure and tune applications designed with modern framework.
  • Adaptability
    Once an application has been modernized, there is a good chance that its functions will continue to evolve. Adopting a proper design framework will ensure that the new application will continue to adapt to new requirements and can be enhanced easily.

But the challenge remains the same by taking the re engineering approach: You still need to migrate the business logic in the original programs to the new code. This is where a tool like Blu Age can facilitate the process.

Introducing Blu Age – A Powerful MDA Tool

Firstly, as the saying goes:“There is no free lunch.” If you are looking for a magical “EASY” button, Blu Age is not it. Blu Age is not an automatic translator. It does not make the end product magically for you by your clicking a button. But it is a tool that can help you get the job done more easily and more quickly.

Blu Age is a tool that:

  • Helps you analyze your program source with built-in visual tools and annotation features
  • Enables you to define reusable code patterns to automate intelligent code segment identifications and conversions
  • Extracts the business logic from your code
  • Assists you in transforming the business logic to new code in Java or .NET

Re-engineering

What is Blu Age?

Blu Age is a commercial software re-engineering and modernization tool suite that follows the Model-Driven Architecture (MDA) approach to generating program code from Unified Modeling Language (UML2) diagrams. MDA is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. It a standard that was launched by the Object Management Group (OMG) in 2001. Blu Age provides all of the re-engineering capabilities discussed earlier, and more. All of Blu Age’s power is based on generating and approving human-readable models that Blu Age then converts into modern code.

Re-engineering

In short, you use UML diagrams to design your application in Blu Age, and it generates the application for the targeted framework according to your specifications .

Blu Age Components
Blu Age is a tool suite built on Eclipse and contains modules that address different components of the modernization process.

Re-engineering

Blu Age Reverse Modeling (BRM)
  • It automates the process of reading your original code (e.g. SCOBOL source) and identifying the interesting and necessary business logic that it will then convert into the diagrams of your model.
  • As you interact with BRM, it identifies and extracts business rules, calculations, and business logic into Unified Modeling Language (UML2) models, ready for you to review and approve.
  • Once approved, your models feed Blu Age’s Forward Engineering (BFE) with accurate business logic functional specifications.
Blu Age Forward Engineering (BFE)
  • Blu Age then applies its code-generation capabilities to automatically transform your models into complete, modern, high-quality application code in Java or .Net.
Blue Age Delivery (BDE)
  • This ensures the quality of the code delivered by BFE. BDE operates in a modern continuous integration and testing environment that is consistent with the today’s best software engineering practices

Blu Age re-engineering approach is different from both rewriting and translating. Rewriting is a laborious set of tasks, the success of which depends of learning ad properly applying new computer languages and new software engineering techniques. Blu Age lets you focus on ensuring the right business logic is transferred from your SCOBOL program to the new target platform.

Blu Age also differs markedly form automated translators. Automated translator converts the SCOBOL program wholesale, leaving you to read through unfamiliar modern code to determine whether the translation appears successful.

Blu Age puts you in the driver’s seat to determine the steps in mapping over the business logic, while relieving you of the burden of coding in a new unfamiliar language, or trying to make sense of automatically translated code.

So, how does Blu Age methodology work? Read about it in our next blog:

Integrating Cloud Computing Services with NonStop

Cloud computing is playing an increasingly key role in organizational IT strategies.  Amazon, Microsoft, IBM, Google and others continue to improve their offerings, making a compelling case for using cloud-based resources.  As providers continue to offer more and more services, new opportunities are presenting themselves.  In this article, we’ll look at some of the products offered by Amazon Web Services (AWS) and how they can be used to introduce big data analytics capabilities for NonStop applications.  In a follow-up article, we’ll take a detailed look at how this solution can be integrated with NonStop applications.

To begin from a common starting point, let’s define cloud computing and its advantages.

What is Cloud Computing?

Amazon defines Cloud Computing as “the on-demand delivery of computer power, database storage, applications, and other IT resources through a cloud services platform via the internet with pay-as-you-go pricing”.  A quick Google search will find all kinds of definitions for Cloud Computing, but they are essentially the same with the key concepts being:

  • On demand delivery of servers, storage, databases, networking, software, analytics, and more—over the Internet.
  • Pay as you go pricing.
  • Accessing computer services over the Internet instead of from your computer or company network.
  • Accessing services that are managed for you by someone else.

There are three types of Cloud Computing deployments, with each one representing a different level of control.  They are: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).

Modernizing with TOP – The Power of Sorting

The Power Of Sorting

I remember a conversation with a group of colleagues about  10 or 12 years ago on predicting the company values of Google and Microsoft.  While all of us were impressed with Google’s growth in Search power at that time, the common consensus was that Google Search Engine was a “one trick pony”, and just couldn’t possibly compete against a well established company like Microsoft with the ubiquity of its Windows operating system and Office tools.  Well, we were wrong. We underestimated how the power of search has literally changed not only how we look for information, but in how we acquire knowledge.

“Finding the information quickly when you need it”

Similarly, quite often we take for granted the simple power of sorting in the GUI world.  But when one operates in the green screen terminal world of NonStop, its absence quite often hinders one’s productivity in accessing information. But did you know that you can harness the power or sorting and many other GUI features in NonStop by using a software tool like TOP (The Operations Pack)?

What is REST Web Service?

webserv_img

Ten or 15 years ago, when people talked about Web Services, you would immediately understand they were referring to SOAP. But these days, if someone says they have a Web Service interface, you need to follow up with the question: “What kind of Web Service – SOAP or REST? ” In fact,  REST is fast becoming the more visible application interface on the Internet.  This blog provides a quick overview of what REST is, and how it compares to SOAP.

Web Services

Firstly, like SOAP, REST is a Web Service, which by definition provides an Application-to-Application interface. So functionally, REST is similar to SOAP in that it enables a Client application to invoke an operation/method in a Server application . Furthermore, REST uses HTTP and HTTPS as the communication protocol, just as SOAP does. Their differences lie in what is underneath the cover.

Log Management- Planning Ahead Saves Time and Resources

Busy person“I am too busy to plan!”

It seems like most IT professionals today are so busy keeping up with day-to-day tasks, not to mention myriad unexpected issues that arise; that project planning and time management often take a back seat., Besides, “planning” sounds like such an “open-ended” thing that is frequently deemed a waste of time and lost in the shuffle.

 

In fact, a little proactive planning could save a lot of time and stress in the future. And it does not have to take up a lot of time, e.g. like planning how to better deal with production issues. Continue reading

Legacy Application Modernization – You Can Have it All

Obsolescence – it’s a fact of life. Wikipedia defines the term as “the state of being when an object, service or practice is no longer wanted even though it may still be in good working order.” We always want the next big thing; the latest Smartphone, the next tablet, the newest car. But with legacy systems – you can keep the past AND have the latest technology. Have your cake and eat it too…

Modernizing legacy applications with the latest enhancements for web services and communications has enabled many firms in a variety of industries to update their current platforms with today’s technology.
