Fact

Over many decades, IT organizations have invested billions of dollars in business logic and data housed in mainframes and within the environment.

Despite the age of these systems, the mainframe and ALCS/TPF continue to provide the most scalable, reliable, and cost-effective platform upon which to conduct critical business operations.

A Typical Business Transaction

I don’t know what you

are talking

No. Talk in my

language

Entire world understand me why I learn your language

I am the future

You are nothing

without me

The language barrierI don’t know either what

you are talking

Talk in my language

Learn my language

I am the future

No. You are nothing

without me

How to solve this language barrier

Today's business environment requires an IT solution that will transform existing systems into flexible building blocks to enable a component-based, process-centric, and cross-platform integration environment.

How to solve this language barrier

Mainframe to learn other languages Non-mainframe systems to learn mainframe

commands/entries Build an interpreter

By adding an integration platform based on a service-oriented architecture, organizations can unlock critical mainframe resources and leverage data and business logic as services, allowing an organization to create a more flexible, dynamic, and agile infrastructure .

Challenge

The challenges presented by most current approaches is to implement Web services to integrate with the mainframe

Typical integration

Conclusion Turbo TPF Scripting Engine, an innovative solution widely

known as T2SE scripting tool, facilitates high performance transaction capabilities with ALCS-based reservations and departure system, delivering booking, fare and availability to B2C interfaces and other satellite applications.

It offers structured data interface with ALCS by building transparency layer around, hides ALCS application's syntax/format dependencies and extends new functionalities to end users without changes to ALCS applications.

Script can be created by non-ALCS / non-assembler programmers thus brings in agility and shrinking time to market for interface and/or integration associated solutions.
