Delta Software Technology

Steel is one of the most important materials. Due to its properties many application areas – from the architecture to the automobile manufacturing – are not imaginable without steel. It is versatile and cost-effective. Steel is the key material for mastering the challenges in the energy sector. These are the very same properties the large German steel company Hüttenwerke Krupp Mannesmann (HKM) expects from its IT applications: stable, reliable, adaptable, cost-effective, a key for the business change.

That is why HKM relies on the generative development tools from Delta Software Technology for the development and maintenance of their IT applications for more than 30 years. Now, HKM accomplished a modernization project to make their applications fit for the future in the service and object-oriented world.

“One of the key reasons we have selected SCORE is that we can make
our mission-critical applications available as services that we can quickly and
easily reuse – without any extra effort – in other contexts, for example
in a service-oriented architecture, Enterprise Portals and the like.”
Gerhard Batiajew, CIO, HKM

From data-oriented Servers to application-specific Data Services

The main steel production processes are controlled and managed by the application system “Stahlwerk Online” (“Online Steelworks”). For storing the production data of “Online Steelworks” HKM uses Informix databases on Fujitsu PRIMEPOWER servers under Solaris. For the development of the data access servers HKM uses SCORE Data Architecture Integration from Delta Software Technology.

SCORE Data Architecture Integration is a generative tool to quickly and easily provide data from the most different sources as real business services within service-oriented or any other application architectures. The developer declares the access structure in models – so-called composition models. From this declaration, the tool generates the entire access code in COBOL– completely and automatically.

The client applications have been developed with the software development system Delta ADS in a Microsoft Windows environment and were also 100% generated – for the productive use in a runtime environment under openUTM COBOL.

SCORE as well as ADS enable the developers to develop the software on a neutral, platform-independent level – without worrying about the technical details. The implementation for the target environment is generated automatically. If one or even more components of the target environment are changed (operating system, database, transaction monitor), the required adaptations in the applications can be automatically implemented by simple re-generation.

To continually ensure flexibility, maintainability and future sustainability, the data access layer of these applications have now been modernized – in multiple ways:

Until now, HKM has worked with servers based on the tables’ definitions, i.e. purely data-oriented servers. As a result, the clients were offered more functionality than they required or were allowed to use in their respective context. Furthermore, this resulted in unnecessary dependencies between client and server side which made the maintenance more difficult. That is why HKM decided to change over to application-specific data access modules – a child’s play with SCORE Data Architecture Integration. The accesses have been defined on model-level by using the Composition Manager. Afterwards, the new data servers have simply been generated. The clients now have data services exactly tailored to their needs. Changes and extensions can now be implemented quickly and securely without any undesirable side effects.
At the same time, HKM took advantage from the upgrade to the latest release of SCORE Data Architecture Integration to implement the existing models not only platform-neutral but also 100% language-independent. Still existing fragments of native COBOL code have been mapped on features of SCORE Data Architecture Integration and are now generated automatically as well.

IT Applications ready for the Future

With this successfully concluded project HKM has increased the maintainability and flexibility of the existing systems. Furthermore, HKM has now made the prerequisite for several possible subsequent steps:

With SCORE Adaptive Bridges the bridge to JAVA now can be built. Adapters and class libraries can be generated directly from the existing models at the push of a button – without having to modify them. New OO applications (e.g. in JAVA) can thereby use the existing (COBOL) servers as real services like components of their own architecture.

Furthermore, from the existing models which are now not only platform independent but also language independent JAVA servers can be generated as well as COBOL servers – real object-oriented code that corresponds to the full extent of the JAVA standards. A “quantum leap” that would not have been possible without SCORE Data Architecture Integration.

Development tools for the change of the IT applications

HKM regularly evaluates its IT technologies. The generative development tools from Delta Software Technology enable the application development teams to modernize their business-critical systems in an easy and risk-free way.

HKM’s IT thereby has the capabilities they also provide for their steel products: Stable, reliable, adaptable, cost-effective, a key for the business change.

“The generative development tools from Delta Software Technology enable us
to modernise our applications easily and risk-free and to
quickly realize cost-oriented decisions.”
Gerhard Batiajew, CIO, HKM

Quotes about AMELIO Modernization Platform - Change your large-scale IT applications with a tailor-made factory: securely, reliably, error-free and 100% automated.

	Provinzial Insurance Germany
Stephan Kaiser Program ‘sponsor’	“The Delta solution has its advantages in two points that are particularly important to us: Due to the complete automation of the transformation, the ongoing development of the system, as requested by the business, was uninterrupted during the entire project. Due to the in-place migration and a parallel operation concept, we achieved absolute security and quality during the migration. The guaranteed operational “smoothness” in the project, despite the complex modernization, is certainly a unique feature of the solution.”
Ralf Prediger Project Manager	“We were impressed by the efficiency and flexibility the AMELIO factory was set up and continuously optimised with. The very good and close cooperation with the Delta managers and employees also contributed significantly to the success of the project.” “Thanks to Delta's transformation strategy, Provinzial succeeded in migrating absolutely securely from IBM IMS to IBM Db2. At the same time, this solution gave us absolute flexibility, as components that had already been transformed and those that had not yet been transformed could be used productively together without any problems.”

	RDW The Netherlands, Groningen
Roland Römer Product Owner	"In the end our decision paid off. Using an automated approach also means almost no freeze and the possibility to change implementations at a very late stage. It enabled us to improve on the end result without any problem. With a manual approach, we would have passed the moment to do something in a different way long before."
Gert-Jan Theuwissen Division Manager ICT	"We now see Delta’s AMELIO Modernization Platform as a kind of washing machine. As long as we chose the right program it will remove a ‘stain’ (technical debt) from our applications. It’s a great solution for when we have mass changes that need to be carried out on our application portfolio."

SCORE Quotes about SCORE Data Architecture Integration - Data as real business services: fast, easy and independent of data architectures and management systems.

	RDW The Netherlands, Groningen
Eric Martens Project Manager	"The fact that we did platform, database and application architecture transformation in one step was way beyond what we expected to be possible. SCORE Data Architecture Integration proved to be the robust and reliable product we needed to keep our data secure and available during this project." "Delta proposed a completely different scenario. They suggested producing with SCORE Data Architecture Integration one data service for each and every program, in a first step even for our old Unisys OS 2200 platform. Our applications would access the RDMS data on Unisys OS 2200 through these services only. This also meant that we started our project with a modernization phase on the existing platform." "After our application architecture had been modernized that way, the next step could take place: Moving our applications to the new Microsoft Windows platform but leaving the data access services on the Unisys OS 2200, accessing them through the remote access options of SCORE Data Architecture Integration. As programs modernized to use the SCORE data services for the data accesses and non-modernized programs interoperated perfectly by means of automatically produced facades, we were able to modernize small clusters one after each other bringing them into production. This made it possible to start our migration project without the need of having the landing platform defined and available at this phase of our migration."
Marcel Rozema Senior Architect	"SCORE's configurable nature enabled us to implement a database error handling registration that cooperated with our old error handling. Modernized and not yet modernized programs did share that part of their functionality. Also the fact that we could decide how and with what middleware the remote solution would be implemented was an important bonus for us." "When Delta suggested using SCORE Data Architecture Integration to develop data access services instead of changing the existing SQL CALL interface code in our existing programs to Embedded SQL, we first had to think about that. In the end the solution has proven to be a key factor that enabled us a smooth step by step migration. Besides, the automated approach that comes with SCORE Data Architecture Integration has improved the quality of the data accesses in our programs."
Wiebrand Rispens Senior Architect	"SCORE Data Architecture Integration also influenced the quality of our software development. In the old situation our programmers had to decide what programs were affected by a database change and had to implement the changes by hand. Using SCORE with its automated approach all relevant data access services are checked against a change in the data model and only if there is a compatibility issue a programmer is needed to carry out the necessary changes. As a result of this we have much more certainty that our programs are correctly using the database."
Geert Pater ICT Manager Architecture & Innovation	"SCORE Data Architecture Integration enabled us to free our application portfolio from its database dependence. Its comprehensive support of distributed applications and automated production of data services for the different mainframe (UNISYS RSA RDMS) and open systems (Microsoft SQL Server) allowed a smooth migration without risk."
Gerard Doll Director ICT	"Working with the people from Delta proved to be a very good choice. They delivered when other companies couldn't. From RDW's point of view Delta is a highly dedicated company with an even higher level of expertise."

SCOUT²

Quotes about SCOUT² Development Platform - Optimized and integrated development processes across all software components, tools and platforms: Stop the “fight against the infrastructure”.

	RDW The Netherlands, Groningen
Gerard Doll Manager ICT	"At RDW we have sensitive applications and very personal data. The security and quality of our development processes are our highest priority. SCOUT² not only allows us to support our mainframe and PC-based development processes, but it also fully embraces our special security and quality management processes." "Delta’s SCOUT² Development Platform not only allows us to support our Unisys OS2200 mainframe and PC-based development processes, but it is also fully embraces our special security and quality management processes."

	HKM (Hüttenwerke Krupp Mannesmann) Germany
Thomas Krieger Project Manager	"Migrating to SCOUT² release 4.0 is very simple and was certainly worth it for us: The user interface is now even more intuitive and one feels immediately at home."

	MIAG C.V., Baar (METRO Group) Switzerland
Silvio Hasler CIO	"SCOUT² isolates the developer from many technical details, dramatically simplifying their work as well as preventing many possible sources of errors. For example, processes such as Generation, Compilation and File Transfers are handled in the background fully automatically by SCOUT²." "The new user interface in SCOUT² makes our developers more productive. Detailed information is always available with a single click, but does not waste screen space when it is not required." “With this migration project we have achieved multiple objectives within the budgeted time and cost. The complete application was transferred from a host-based environment to a client-server platform with the addition of a GUI interface for the end users. The host environment was completely replaced. Using Delta products allowed the migration to quickly and efficiently proceed with the vast majority of the work being at the purely technical level.”

	Kanton Aargau Switzerland
Waldemar Fohmann Software Development Environment Project Leader	"SCORE bringt uns einen erheblichen Qualitätsgewinn, den wir erst noch mit weniger Aufwand erreichen: Denn generierter Code ist ganz einfach richtig – der Aufwand für die Qualitätssicherung und das Testen vermindert sich beträchtlich. Die neue SCOUT² interaktive Entwicklungsumgebung von Delta ist bezüglich Komfort ein Quantensprung. Solche Werkzeuge verbessern die Arbeitsqualität erheblich."

WGKK decided for the automated modernization with AMELIO Modernization Platform from Delta Software Technology, because two goals could be achieved at one go:

Faster applications by modernizing the data accesses.
Platform independency to simplify the migration to more cost-effective platforms later on.

About WGKK

Wiener Gebietskrankenkasse (WGKK – Vienna health insurance) provides - together with its contractual partners - efficient and profound medical care for its 1.124.000 insurants and their 400.000 non-contributory relatives. It is a public corporation and organized as self-government - just like the other Austrian social insurances. This form of organization guarantees to be as close as possible to the insurants and independent from state.

The WGKK continuously extends its services to conform to the social and rapid medical developments.

Increased Performance and Simplified Platform Migration

With the help of AMELIO Modernization Platform from Delta Software Technology, the WGKK replaced all database accesses previously using an Assembler call interface with Embedded SQL (ESQL). By this modernization WGKK could increase the performance of the application package “Leistungen” for insurance payments and services significantly. At the same time the modernized applications became portable and thus were prepared for a platform migration.

"AMELIO allowed us to build a modernization factory that reduced the effort needed for a critical SQL migration project in our core UNISYS OS 2200 applications by 70%.
Our trust in AMELIO was also repeatedly confirmed in other transformation projects, including Y2K and an ACOB/UCOB COBOL compiler migration project"

Suva use Generative Programming Tools to Maximize Return on Investment when Integrating Legacy COBOL Applications in a Thin-Client Architecture

Suva is the Swiss national accident insurance organization covering 100,000 companies and 1.9 million people. Their challenge was to migrate critical applications from legacy OS/2 fat clients to a distributed thin-client architecture using Java GUI, Windows 2000 servers and Citrix MetaFrame connected to IBM AIX servers with Oracle WebLogic and a central DB2 database running on IBM S/390 mainframes.

"We set an aggressive schedule for this project. We were impressed that using SCORE Integration Suite we managed to consistently achieve productivity improvements of 400% to 600%. We are now working on our strategy for future projects with Delta."
Thomas Müller, Manager Application Architecture and Methods, Suva

The critical business and data access tiers of Suva’s application were developed in COBOL and had to be directly reusable in the new architecture. The presentation tier was to be redeveloped using Java. Oracle Tuxedo was selected for communication from Java clients and the application server.

After a careful evaluation Suva selected SCORE Integration Suite from Delta Software Technology to migrate these critical business applications to the new thin-client architecture.

SCORE Integration Suite is a cost-effective and highly productive solution for exploiting the value of existing legacy applications and data stores by service-based integration. SCORE Integration Suite combines integrated software tools, processes and related professional services to create adaptive services with interface intelligence, service agility and service quality.

In this project SCORE Integration Suite provided Suva with a quick and easy way of taking their existing COBOL business logic and data access tiers and directly reusing them within their very different new architecture. SCORE Integration Suite generated all necessary server-side component and middleware frames in native COBOL to expose existing functionality as services with well-defined interfaces.

Client-side proxies were generated in Java to allow the services to be used by the new Java clients. The platform portability of SCORE Integration Suite enables Suva to use the same server instances with a range of alternatives client technologies. Initial testing is already underway with J2EE/EJB clients.

"We generated services for diverse middleware and platform combinations – SCORE Integration Suite handled this effortlessly."
Thomas Müller, Manager Application Architecture and Methods, Suva

A project as large and complex as this (30,000 source files and 12,000,000 lines of code) naturally raised non-standard requirements and numerous special cases. The flexibility of SCORE Integration Suite enabled the Suva team to solve these requirements.

Using the concepts of "Generative Programming" and early versions of "Pattern By Example" and the "ANGIE" frame-based generator, the Suva team automatically generated a series of non-standard components, including a complex test framework and an additional client proxy layer to integrate with a new Java GIU framework.

Working with SAXOS Informatik AG, Delta’s distributor in Switzerland, Suva was able to maximize the return on investment in their legacy COBOL applications by directly reusing more 5,000,000 lines of COBOL code in the new architecture. The new application is now in production and supporting a full production workload with more than 2,000 clients located at Suva’s 22 branch offices throughout Switzerland.

"With SCORE Integration Suite we see the results of our long-term commitment to generative programming and other emerging technologies. They are already giving our customers a significant advantage in the market, and in today's business environment everyone needs all the help they can get."
Rüdiger Schilling, Managing Director, Delta Software Technology GmbH
