Businesses grow and compliance legislation increases, yet IT budgets never quite seem to keep up. One way to minimize computer overheads and save CO2 emmitions, is to reduce the volume of data that needs to be processed and stored.

Data compression has been around for a long time but it’s almost always offered at the file or volume level. File level compression is fine if you’re unlikely to ever want to recover the data again but what if you need an item of information in a huge compressed archive? How would you even find it?

Also, if users discover that they may have to wait days to access archived information, they won’t let you archive it. Why should they suffer inconvenience, just to save the IT department some cash?

Given that “75% of the world’s business data is still processed on mainframe applications written in COBOL.” (Gartner Group) and “Mainframe application workloads have grown 19 percent annually for the past 5 years.” (IBM), archiving and compression is particularly acute in the mainframe COBOL environment.

What’s needed is a simple field level compression routine that: Keeps data accessible to real-time applications. Easy to compress. Very fast to decompress. Designed for COBOL data formats (COBOL data often contains binary strings which are difficult to compress).
