Recovery And Migration Of Application Logic From Legacy Systems
Future Internet technologies necessitate dramatic changes in system design, deliveryand usage patterns. For many legacy applications it means that their furtherdevelopment and transition to the Internet becomes problematic or evenimpossible due to the obsolescence of technologies they use. Replacement ofthe old system with the new one, built from scratch, is usually economicallyunacceptable. Therefore, there is a call for methods and tools supportingthe automated migration of legacy systems into a new paradigm. This paperproposes a tool supported method for recovery and migration of applicationlogic information from legacy systems. The information extracted from a legacyapplication is stored in the form of precise requirement-level models enablingautomated transformation into a new system structure in a model-driven way.Evaluation of the approach is based on a case study legacy system
TRANSLATION OF USE CASE SCENARIOS TO JAVA CODE
Use cases are usually treated as second class citizens in the software developmentchain based on models. Their textual descriptions (scenarios) are treatedas informal input to more formal design models that can then be (semi-)automatically transformed down to code. In this paper we will show that usecase scenarios can gain precise metamodel-based notation and semantics enablingautomatic processing. What is more, we will show transformation algorithmsthat can transform use case scenarios directly to dynamic code in Java.The presented transformation can generate the full structure of the system followingthe MVP architectural pattern, including complete method contents forthe application logic (Presenter) and presentation (View) layers. It also providesa code skeleton for the domain logic (Model) layer. The use case notation andthe transformation were implemented within a sophisticated tool suite. Basedon this, the paper discusses the evaluation efforts based on a case study
Agri-food business: Global challenges â Innovative solutions
The rise of a western-style middle class in many successful emerging economies like China currently is inducing deep structural changes on agricultural world markets and within the global agri-food business. As a result of both higher incomes and concerns over product safety and quality the global demand for high-quality and safe food products is increasing significantly. In order to meet the new required quality, globally minimum quality standards are rising and private standards emerging. All over the world these developments cause adjustments at the enterprise, chain and market levels. At the same time, the tremendously increasing demand for renewable energy has led to the emergence of a highly promising market for biomass production. This has far-reaching consequences for resource allocation in the agri-food business, for the environment, for the poor in developing countries and for agricultural policy reforms. The challenges increase with ongoing liberalisation, globalisation and standardisation, all of which change trade patterns for agricultural and food commodities, and influence production costs and commodity prices. The objective of the IAMO Forum is to show opportunities as well as risks for all participants of the food economy in the ongoing globalisation process: for small peasants in developing countries, farmers in Europe and globally active food enterprises and retailers. The success of enterprises depends on the ability to find innovative solutions with regard to the organisation of enterprises, chains, and markets, as well as future policy design. Concerning bio-energy strategies has to be identified to combat global warming most efficiently and concurrently attenuate the competition between "tank and table" on farmland. IAMO Forum 2008, as well as this book, would not have been possible without the engagement of many people and institutions. We thank the authors of the papers, as well as the referees.

Agri-food business: Global challenges – Innovative solutions
The rise of a western-style middle class in many successful emerging economies
like China currently is inducing deep structural changes on agricultural world
markets and within the global agri-food business. As a result of both higher incomes
and concerns over product safety and quality the global demand for high-quality
and safe food products is increasing significantly. In order to meet the new required
quality, globally minimum quality standards are rising and private standards emerging.
All over the world these developments cause adjustments at the enterprise,
chain and market levels. At the same time, the tremendously increasing demand
for renewable energy has led to the emergence of a highly promising market for
biomass production. This has far-reaching consequences for resource allocation
in the agri-food business, for the environment, for the poor in developing countries
and for agricultural policy reforms. The challenges increase with ongoing liberalisation,
globalisation and standardisation, all of which change trade patterns for
agricultural and food commodities, and influence production costs and commodity
prices.
The objective of the IAMO Forum is to show opportunities as well as risks for
all participants of the food economy in the ongoing globalisation process: for
small peasants in developing countries, farmers in Europe and globally active food
