ALCHEMIST is a general purpose object-oriented transformation generator. ALCHEMIST provides a new approach to developing transformations between any well-defined representations. It allows users to define the syntactic structure of the data representations and the related structure associations with a grammar notation. These grammars can then be augmented with semantic operations. From this description...
Recent developments in knowledge-based systems technology offer an excellent and effective approach to building management support systems for strategic management. We have developed a hyperknowledge support system for strategic management in the forest industry, and have tried it out in several strategic business units in a major corporation. The core of the system is an object-oriented expert system,...
There are many problems facing scientists in their efforts to use computers to manage, access, and analyze data. One serious problem is the heterogeneity of data sources. Previous research into accessing heterogeneous data has not addressed problems with accessing large data sources that are not managed by database management systems. We believe that an object-oriented database management system can...
Meeting memory features are poorly integrated into current group support systems (GSS). This paper discusses how to introduce meeting memory functionality into a GSS. The author first introduces the benefits of a good meeting and organizational memory to an organization. Then, challenges such as storing semantically rich output, building up the meeting memory during the meeting with a minimum of additional...
The emerging research area of computer supported cooperative work (CSCW) has yielded a number of groupware applications in recent years. The application and installation of these systems in large organization or for the support of inter-organizational cooperation requires information about the organizational environment in which they are used. The TOSCA system which is described aims to provide that...
In his research the author is looking into the cooperation of methodology, language, and database in the design of object-oriented systems which are to be realized in an object-oriented programming language using an object-oriented database system (OODBMS). The focus is on some of the differences between traditional object-oriented design and object-oriented database design. For this purpose a small...
We present a framework for making a specialized genome database interoperable with a public database. Specifically, we study how to grant users of the E. Coli genome database EcoSeq to access data remotely available from GenInfo. We extended the Object Loader software tool developed by NCBI to translate ASN.1 instances to and from C++ data structures. In our prototype system, EcoSeq and GenInfo are...
Biochemical techniques have given to biology experimental tools for sequencing genome fragments. These fragments were of a short length/spl minus/often corresponding to a single gene/spl minus/until the development of extremely fast sequencing methods. Now, large sequencing projects have been started, leading to the availability of huge continuous fragments (300 kBytes for yeast chromosome III). Besides...
We developed a deductive object-oriented language for flexible genome analysis, and implemented it on an object-oriented database for genome data. The language does not support method and class definitions. Therefore, object-oriented features, such as inheritance and override, depend on the OODB and the language can be used to call methods from the OODB and to search for objects. It provides simple...
We present on-going research concerning an object oriented associative memory. It is a massively parallel architecture, fully programmable and configurable, composed of VLSI circuits. It is well adapted to genome data processing. DNA and proteins sequences alignment is a very important application in biology research. Standard sequences alignment usually entails software implementation with disastrous...
