Nowadays, there are many popular different notations of business process modeling, such as, e.g. BPMN [1], for a software analysis. Modeling of business processes at the conceptual level allows domain experts to cooperate in the analysis and to design the software. The whole business process model can be later translated to web services and executable BPEL [2] scripts which orchestrate all related parts together. Besides this automatization, it is necessary to define the structure of each data object in the business model. Web services usually communicate by exchanging XML documents [3]. Therefore, a software architect has to define also an XML schema of XML documents by an XML schema language, e.g. XML Schema [4].In this paper, we present a method which derives and adapts optimal communication XML schemas for a given conceptual schema of a business process, complemented with a conceptual schema of exchanged data. We use a view on a part of a Platform Independent Model of a whole system as conceptual schema of exchanged data. We derive several XML schema documents from given inputs and choose the one which has minimal values for three metrics. The result of these three metrics is a measure of a quality of an XML schema document with respect to conceptual model of exchanged data and business rules applied on this document.

The most common applications of the today's IT world are information systems. The problems related to their design and implementation have sufficiently been solved. However, the true problems occur when an IS is already deployed and user requirements change. Currently this situation requires a skilled IT expert who knows all system components and, hence, is able to identify and modify all the affected parts. However, not always we have such an expert, whereas for complex systems it is a very hard and error-prone task. In this paper we introduce DaemonX -an evolution management framework, which enables to manage evolution of complex applications efficiently and correctly. Using the idea of plug-ins, it enables to model almost any kind of a data format (currently XML, UML, ER, and BPMN). Since it preserves relationships among the modeled constructs, it naturally supports propagation of changes to all related affected parts. We describe the general proposal of the framework and, then, its architecture and implementation.
