Headquartered in Stockholm, Sweden, Scandinavian Airlines (SAS) is the largest airline in Scandinavia. It flies to 150 destinations, employs 32,000 staff, and carries 40 million passengers annually. The mainframe data warehouse had become expensive to run and maintain and it was becoming difficult to deliver the Business Intelligence vital to competing within the airline industry in a timely manner. SAS chose to migrate to Windows, achieving improved customer satisfaction, faster time-to-market, reduced costs and increased revenue per customer. |

Business Intelligence (BI) is vital to competing within the airline industry. However, at SAS, the mainframe data warehouse had become expensive to run and maintain and it was becoming difficult to deliver the BI in a timely manner.
The BI data warehouse was hosted on the same mainframe as other critical business processes, so applications supporting BI were treated as a lower priority. This meant the BI batch processes could take as long as six hours to complete, severely impacting the timely delivery of BI reports to business analysts.
SAS realised it had to dramatically modernize its BI capabilities to deliver near real time scenario for reporting and analysis. SAS needed a data warehouse with desktop tooling that did not have to compete for mainframe resources and which analysts could use to quickly customize reports, rather than SAS having to rely on an expensive external vendor.
SAS initially looked to write new applications to run on a Windows Server utilizing Microsoft® SQL ServerT 2005 but cost implications, time to market and risk involved meant this was simply not viable. This is when SAS turned to Micro Focus.
The Solution
SAS approached Micro Focus as it offered a variety of low risk approaches to Application Modernization. After discussing the options, SAS decided to modernize the BI capability by reusing its existing mainframe applications on
an Intel server running Windows.
MigrationWare, a strategic Micro Focus partner, was chosen to undertake the migration of the COBOL/DB2 applications and the associated Job Control that was the backbone of the BI environment.
SAS used the Micro Focus' Revolve analysis tool to map out the viability of the migration from the mainframe to Windows and ensure they adequately scoped the project.
Micro Focus Studio and Micro Focus Server were used to enable the existing COBOL and JCL to be re-used with minimum change and to capitalise on existing COBOL/JCL programming expertise.
SQL Server was selected as the new data warehouse repository and Microsoft Active Directory was utilized to implement appropriate security over the network.
MigrationWare undertook the actual project to move the mainframe applications to Windows including the conversion of VSAM data files and the migration of all the relevant mainframe DB2 data to SQL Server. In addition, MigrationWare provided technology to ease the application migration by emulating the behaviour of standard DB2 utilities against SQL Server.
