Abstract Most engineering tasks are highly data intensive coping with the increasing complexity of systems. Gigabytes of heterogeneous engineering data have to be managed consistently by a huge array of tools. This necessitates sophisticated integration techniques based on a common database management system in order to decrease the amount of data that have to be exchanged between these tools. In this paper we present a new approach to distributed design frameworks, integrating graphical as well as text processing tools. Tools may online share the same graphical and logical data synchronized by the event mechanism of an object management system. The synchronization concept is based on a tight integration into an object-oriented object management system and provides means to keep the graphical views of multiple agents consistent. We outline these concepts by the example of an integrated EXPRESS modeling workbench.

Database reverse engineering consists of recovering the abstract descriptions of files and databases of legacy information systems. A legacy information system can be defined as a “data-intensive application, such as [a] business system based on hundreds or thousands of data files (or tables), that significantly resists modifications and changes” (Brodie & Stonebraker, 1995). The objective of database reverse engineering is to recover the logical and conceptual descriptions, or schemas, of the permanent data of a legacy information system, that is, its database, be it implemented as a set of files or through an actual database management system.

AbstractAn object-oriented medical database management system is presented for a typical cardiologic center, facilitating epidemiological trials. Object-oriented analysis and design were used for the system design, offering advantages for the integrity and extendibility of medical information systems. The system was developed using object-oriented design and programming methodology, the C++ language and the Borland Paradox Relational Data Base Management System on an MS-Windows NT environment. Particular attention was paid to system compatibility, portability, the ease of use, and the suitable design of the patient record so as to support the decisions of medical personnel in cardiovascular centers. The system was designed to accept complex, heterogeneous, distributed data in various formats and from different kinds of examinations such as Holter, Doppler and electrocardiography.
