A direct manipulation object-oriented environment to support methodology-independent CASE tools : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University

The aim of the thesis is research into application of direct-manipulable OO graphical environments to the development of methodology-independent CASE tools. In this thesis, a Methodology-Independent Graphical OO CASE Environment (M1GOCE) is proposed. MIGOCE consists of three parts: OO Notation Workshop, OO Notation Repository and Universal OO Diagramming Tool. OO Notation Workshop is an OO graphical editor which is used to design existing and new notations; OO Notation Repository is a notation database that stores different notations designed by the notation workshop; Universal OO Diagramming Tool is an upper-CASE graphical environment, by which a user can draw arbitrary OO diagrams of different methodologies. The MIGOCE database management system provides OO notation sets management, OOA/OOD diagrams management and OO repository management for data integrity and sharing. MIGOCE has three outstanding characteristics: Methodology-independence, Directly-manipulable graphical environment and Easily-expanded program structure MIGOCE is completely methodology-independent. It not only supports existing OO methodologies, but also supports users' own notation designs. It provides support for mixing, updating existing methodologies or defining new ones. It typically allows the user to switch quickly different OO notation sets supported by corresponding methodologies for designing diagrams. Direct manipulation interfaces of MIGOCE enable it more flexible and distinctive. The user can easily add, delete, edit or show notation shapes, and get the system feedback very quick on the screen. The MIGOCE system itself is programmed using object-oriented programming language - C++. Its program structure enable the functions of itself easy to be modified and expanded. Although MIGOCE is a prototype, it provides a new way to develop the real methodology-independent OO CASE environment. So far, the way and style taken by MIGOCE have not been found in OO CASE literatures. This system gives a complete possibility of implementing a methodology-independent OO CASE tool and shows distinct effectiveness of such a tool in practice

Object-oriented database management systems for construction of CASE environments

We argue that a fully object-oriented database management system is a very suitable basis of every modern CASE environment. We describe how the features provided by an OODBMS are exploited to build a CASE tool or environment. We discuss especially problems concerning inter-document consistency constraints and multi-user support. We finally sketch the features which are still missing in OODBMSs

KATS: A Knowledge Acquisition Tool Based on Electronic Document Processing

This paper describes a particular knowledge acquisition tool for the construction and maintenance of the knowledge model of an intelligent system for emergency management in the field of hydrology. This tool has been developed following an innovative approach directed to end-users non familiarized in computer oriented terminology. According to this approach, the tool is conceived as a document processor specialized in a particular domain (hydrology) in such a way that the whole knowledge model is viewed by the user as an electronic document. The paper first describes the characteristics of the knowledge model of the intelligent system and summarizes the problems that we found during the development and maintenance of such type of model. Then, the paper describes the KATS tool, a software application that we have designed to help in this task to be used by users who are not experts in computer programming. Finally, the paper shows a comparison between KATS and other approaches for knowledge acquisition

Integrating differentiated landscape preferences in a decision support model for the multifunctional management of the Montado

A great part of the Alentejo region in Southern Portugal is covered by an agro-silvo pastoral system, the Montado. This traditional landuse system is specific, inter alia, in its ability to join production with favorable conditions for non-production functions. At the present time, as society positively evaluates and even demands cultural and amenity functions from the countryside, the Montado management faces the challenge of integrating production with non-production functions in a way which will result in suitable multifunctionality, and a more sound viability of the whole system. The decision support tool (DST) for the cork oak Montado management, the CORKFITS, based on the singletree growth model and working at the stand level, is oriented primarily to the management of the production functions, but it is able to integrate also other data that can contribute for a more multifunctionality oriented management. In this exploratory study, the integration in the DST, of the preference distribution, as expressed by landscape users is investigated. The aim was to test a more comprehensive functioning of this tool, where non-production functions are also integrated. The described integration intended to communicate to decision-makers how the change in management practices at tree and under cover level, might alter the satisfaction of expectations of different user groups, as such changes affect the composition of the Montado, at both levels. The users considered are those practicing non-production functions in the Montado. Preferences were assessed through a questionnaire survey applied in the region of Alentejo, in the area of dominance of the cork oak, in the Montado system. The non-production functions are, in this context, related particularly to hunting, aesthetic appreciation related to walking and other leisure activities, to life quality, and to tradition and identity, as well as bee-keeping and mushroom picking. This paper focuses on the description of the specific methodological steps applied for the successful integration of the landscape preferences of different user groups into the DST for the cork oak Montado. Integration has proved to be possible, even if some methodological challenges still need to be faced for a more consistent use of the proposed tool

A tool for test automation with support for remote tests

This paper presents an interactive MS-Windows ®-based tool for high-level specification and analysis of tests on printed circuit boards, using the IEEE 1149.1 standard, and also on integrated circuits using scan design like the LSSD testing methodology. As novel contributions we provide an object-oriented tool for Boundary Scan and LSSD test automation with support for remote tests, including interfaces to circuit description, chip interconnection, test vector analysis and test vector generation. The system is a reasona'.Jly complete CAE test system that includes features like remote testing (using client- server technology), project management computer-aided learning support, menu-based command entry, user-defined configuration and a comprehensive set of commands. Thus, by using this system, a test engineer or a circuit designer are able to specify and verify tests for printed circuit boards or for integrated circuits, either ocally or remotely

Management Control System in the University of Debrecen

AbstractThe statement that limited resources together with the unlimited user demand force Universities, Colleges to follow the principle of strictly target-oriented financial rationalism is becoming more and more valid these days. A full scale reorganization of the financing system of higher education is in progress in Hungary and the University of Debrecen would like to maintain its status in this process. The management is required to monitor the changes of the environment continuously, and apply the necessary tools in order to reach its strategic goals. A gradually emerging need is that this educational unit have to frame operating structures that are suitable for flexibily following the changes occurring in its environment. This is the terrain where the management can be supported by the management control system, which is in fact means of regulating operations and driving preparations for decision-making. This study directs attention to the importance of the management control system, and the fact that by today this tool for the support of decision-making has become indispensable even for budgetary organizations

Personal Document Management System

In definition, a document management system (DMS) is a computer system (or set of computer programs) used to track and store electronic documents and/or images of paper documents As people nowadays are constantly on the move and the wide spread availability of internet access, the usage of web based systems are increasing by leaps and bounds. And the amount of data and information that is being created and stored is getting bigger by the moment. Sometimes, people who are constantly on the move might forget to bring along their files and documents and there might be a situation when they will need those files and documents urgently. Most of the people might not even be aware of a system available online that would help them organize their files and documents. This might be caused by the fact that these systems are more oriented towards enterprises and businesses. Seeing this situation, the author has initiated a web based system project that is more oriented towards a more personal version of a document management system. This personal document management system will enable users to manage and organize their files easily .Files and documents will be stored centrally on a server and this centralization enables users to access them anytime anywhere through a web based portal. This personal management system is designed as an online system that is install on individual computers where it allows user to upload, retrieve, view, edit, delete, share and even send files to other users that uses the system. In the process of developing this system, the author has done online researches on similar systems and for information that are related to the development of the system. Along with a user intuitive interface with heavy emphasis on usage of icons and graphics, it makes it easier for users to understand the system and ultimately find it as a useful tool to make their everyday life easier

Large Scale Data Streaming

Over the last few years, applications that require real-time processing of an huge amount of data are pushing the limits of traditional data processing infrastructure. Many applications in several domains such as telecommunications, large scale sensor networks, financial, online applications, computer network management, security and others, require real-time processing of continuos data flows: this kind of computation systems are usually called Data Stream Management Systems (DSMSs) or Stream Processing Engines (SPEs). Traditional Data Base Management Systems (DBMSs) implements the store than process paradigm; it means that: data require to be stored (persistently) and indexed before they could be processed and data processing is asynchronous in relation to their arrival. In DSMSs data streams are not stored but are rather processed on-the-fly using continuos queries: the query is constantly standing over the streaming data and results are continuously output. One of the most famous and used DSMS is called Storm. Storm is a powerful tool and has a simple programming model, but it does not provide a bulit-in implementation of stream-oriented operators: this is a strong limitation because the user is forced to write a case-specic implementation every time. The goal of the work described in this thesis is to build a distributed real-time computation system on top of Storm, called Enhanced Storm, that provides to the user built-in relation algebra and database-specic operators for streaming computation. Enhanced Storm maintains Storm fault-tolerance and scalability: in this way we supply to the user a generic, high performing and easy-to-use system. Enhanced Storm was developed at the Distributed System Laboratory(LSD) of the Universidad Politecnica de Madrid(UPM)[UPM]
