Trends Industry signals to keep you in the know Automatic Transition Batch modernization redefines application development By Gary Puchkoff and John Eells 12 MARCH/APRIL 2013 B atch is boring, right? Wrong! Look at it this way: Interactive is manual. Batch is automatic. Let’s examine it further, starting with the definition of batch. Batch processing is usually another way to say, “automatic processing.” This need is met differently on various computing platforms. UNIX* has cron daemons, Microsoft* Windows* has scheduled tasks, and so on. Although ad hoc initiation of these processes is possible, this discussion will focus on automatic, scheduled processing. It might seem like there’s nothing new or valuable about batch. But in recent years, with the emergence of new application frameworks such as J2EE and increased focus on online interactive work, application architects have developed a new appreciation for batch across the IT landscape. Many years ago, architects designed data-processing systems based on batch and added online access later. Today, interactive access takes precedence, and batch has almost fallen out of favor. The time spent on batch was progressively reduced to provide less disruption for online access, leaving typically short batch windows for activities that couldn’t be overlapped as application architects focused more on how customers interact directly with their systems. User experience is an important aspect of system design but equally important is focus on the system’s efficiency and scalability. This is where due consideration for batch programming is really needed. Built on Batch z/OS* technology has been built from the ground up with extensive support
