Presentation Notes
The Micro Focus belief is that you already hold all the information you need within your organization to be competitive – although it’s locked away in the complexity. We help unlock the value from that complexity. And, since 1976, we have worked with thousands of clients to help them unlock that value.

Presentation Notes
In short - nothing new – COBOL apps are huge and getting bigger! These slides help support message we will promote later in the deck We ran a WW survey across all orgs using COBOL – be that our COBOL or anyone elses. Let’s look at some of the results: First of all, COBOL apps are huge and getting bigger. No surprise they’ve been under development for years or decades for some LOC – Lines of Code It’s one of the reasons why COBOL applications don’t disappear quickly – they’re so massive and contain so many business rules they’re incredibly difficult to replace without considerable cost/risk We also see that businesses will be keeping the size of these apps about the same or growing them

Data Modernization
Market research highlightsCOBOL applications are a business critical asset
Cobol shops plan to modernize using… Rank
RDBMS Integration 1Java or .NET Integration 2
SOA/Web Services/REST 3
Cloud & Virtualization 4
Of COBOL applications are considered ‘strategic to the business’ 85%
Will maintain current COBOL apps, but seek to improve efficiency
2/3Have active modernization projects over the next two years
42%
A drive to reduce IT costs, address COBOL skills concerns and modernize application delivery
The larger the application, the greater the strategic value
Modernize COBOL Data AccessRelational database tooling
1. Embedded SQL: COBOL programs use SQL syntax to directly access RDBMS
