Enterprise Resource Planning (ERP) represents a general business application software solution which is applicable in different business operations. Therefore, it covers areas which are common to a certain group of business operations (e.g. manufacturing, services, financial services, public services, etc.). However, business operations, no matter if they belong to the same or different group, have specific areas which are not supported in general ERP solutions. This paper attempts to reveal which business operations are supported by specialized ERP solutions, how to measure the size of specialized ERP producers, how many business operations are supported by ERP producers on average, and whether there are any classifications of ERP producers based on the number of supported business operations.

Data modelling is a complex process that depends on the knowledge and experience of the designers who carry it out. The quality of created models has a significant impact on the quality of successive phases of information systems development. This paper, in short, reviews the data modelling process, the entity-relationship method (ERM) and actors in the data modelling process. Further, in more detail it presents systems, methods, and tools for the data modelling process and identifies problems that occur during the development phase of an information system. These problems also represent the authors' motivation for conducting research that aims to develop a knowledge-based system (KBS) in order to support the data modelling process by applying formal language theory (particularly translation) during the process of conceptual modelling. The paper describes the main identified characteristics of the authors' new KB system that are derived from the analysis of existing systems, methods, and tools for the data modelling process. This represents the focus of the research.
