GSE Guide Share EuropeThe working groups of the Guide Share Europe provide a platform for the exchange of practical experience in all aspects of IT. The information enables the members to ensure the effectiveness of their installations, to make sound decisions in a well informed manner and to influence the product development of IBM and its partners.

The working group BSMSD IMS-System Management (BSMSD IMS-Systemverwaltung) deals with the database system IMS, with an emphasis on the Transaction Manager and the organization of operation procedures. The next meeting of the working group is aligned this time by the LVM insurance and will take place in Münster.

We are particularly pleased that we are allowed to introduce ourselves. Delta Software Technology presents on April 14 at 1:50 pm:

"Successful ways to replace IMS databases"

The replacement of the IMS databases is currently on the agenda of many companies - for good reasons:

Waning expertise and outdated database technology lead to high costs and make it difficult to use modern technology for centralized IT applications. This applies not only to network systems but also to the high-performance IMS database systems.
Increased effort arising through parallel use of various database technologies and additional necessary processes (ETL), and ensuring data consistency, lead to enormous costs. It lacks the flexibility of relational databases for quick, unrestricted accesses to the data. The expertise of the implemented applications written in COBOL and PL/I dwindles as well as the necessary technical expertise of IMS. The connections with new technologies (mobile, cloud, etc.) are difficult.
Though, the obstacles to the replacement of IMS databases and the consolidation of the data are enormous: The mainly business-critical applications have evolved over decades, and are very large and complex. The existing documentation is not suitable for such projects. The modernized applications must be as performant as the original IMS applications.
The modernization of the applications can be automated by using the tools of Delta Software Technology. Delta Software Technology presents a current project taking benefit of the automatic application transformation to replace IBM IMS/DB. Discuss with Delta about safe ways how to preserve the functionality and performance of your applications and switch without risk to relational systems.

Modernization Project at BSQ Bauspar AG

CGI Germany selects Delta Software Technology as partner for the modernization project at BSQ Bauspar AG.

BSQ Bauspar AG plans to migrate its core application package. The project includes also the migration of the complete infrastructure. Particular attention will be paid to the transformation of the database management system IMS/DB to a relational database management system. CGI Germany was chosen as general contractor for this modernization project. Delta will provide the technology for the automated migration.

"Tools support for the requirement engineering for the modernization of legacy system – Procedure and Example"

IT systems with origins in the 1980's or even earlier, still form the core of business-critical applications at e.g. banks and insurance companies. The maintenance of these systems still determine a large part of the system development in these companies. Especially the integration of new requirements in the existing system is often associated with considerable effort. At some point, a further development is no longer useful or possible, as the necessary expertise about the application and development techniques used is not available anymore or because current requirements cannot be implemented technologically. For a modernization projects, the question arises how the functionality of the legacy system can be identified and described usefully in requirements in order to assist the development of a new system. The applications are usually very large and complex, so a manual determination of requirements, even with the support of specialist staff, is very expensive and error-prone if possible at all.
Therefore, we propose an approach which focuses on the automated analysis of the legacy system. This analysis identifies the architectural description of the legacy system. Architectural elements are to be determined and classified into a defined architecture concept. This architectural concept is independent of the original and future technologies and therefore easily accessible for new developers. As part of this process, metrics for complexity description of the architecture are determined. So you can using these metrics assess them and decide whether the most complex components to be upgraded first or last.

We present the above process with the example of modernizing macro-based generators aiming at the modernization of these these generator. The process and a first tool development was carried out in the context of the research project AmAVaG, funded by the German Ministry for Education and Research. The concept has been implemented in a prototype during the project and validated using different large IT systems in the financial and the public sector.
