Ontology Based Multi-site project management (the domain of analysis) is a growing practice with little documented research. It has many knowledge-based issues resulting from the dispersion of people, systems and resources. An ontology knowledge system is proposed as one solution that would help resolve these issues. This research examines the literature of ontology and identifies a methodology of how these principles can be applied to design a knowledge based system architecture for enabling multi-site project management, and describes the resulting ontology system architecture. The research methodology is qualitative and orientates towards a science and engineering model. It collects prima facie knowledge about the domain using case study methods. It analyses and infers the requirement scope of multi-site project management and design-components of the system solution by using an induction approach of grounded theory, where theory is inductively derived from a body of knowledge (data). Research theory testing is performed using system testing methods and takes a program evaluation approach in evaluating if the research has succeeded in designing an effective knowledge system solution for resolving the knowledge issues of multi-site project management
Human Disease Ontology Research, This proposal describes the increasing role of ontologies for obtaining, comparing and analyzing distributed heterogeneous scientific data. In communities of people committed to a common goal, the management of resources and services becomes very important. We have chosen the application domain of human disease research and control to investigate. A characteristic of the domain is that trusted databases exist but their schemas are often poorly documented, if at all. The network of biomedical databases forms a loose federation of autonomous, distributed, heterogeneous data repositories ripe for information integration. Computer based ontologies may be seen as shared formal conceptualization of domain knowledge and therefore constitute an essential resource for enabling interoperation in an open environment such as the internet.
We adopted the DOGMA formalism for the description and terminology involving ontologies.
The GHDO aims to also support the study of complex disorders caused by many different factors simultaneously, for example, the case of psychiatric disorders. The source information covers different areas of interest with respect to human diseases in order to allow different user categories (each having specific intentions), to query the system. Our intelligent information system will act as a support tool for physicians and medical researchers.
Automated Enterprise IS System Though Ontology and Meta-data, Recent technology advances have not fundamentally altered the common core system development methodologies for Enterprise Information Systems ( EIS ) such as the Waterfall, Spiral, Fountain and V models and in general we are still maintaining the basic paradigm for system development as the traditional stages of; analysis, design, develop code, test and deploy. New system development methodologies such as Prototyping and Agile Processes can provide specific advantages when dutifully employed but they are not guaranteed to necessarily change the magnitude of the total effort.
This research project proposes that performance of the analysis and efficient collection of this information can also perform the bulk of the design phase for an EIS, largely as a simultaneous activity. Further, with the collective design requirements stored and available in a suitable meta-data model, this research aims to develop meta-data for a Model Driven Architecture so that EIS systems can be generated automatically with the availability of appropriate runtime components. This expectation is based on the well structured nature of EIS applications; highly visual and interactive applications that prompt for the entry of appropriate transaction data by the application users, employ strong rules based actions and utilise database transactions to complete the action? they tend to be a technically simpler subset.
The available technology to improve database accessibility has progressed substantially since the rise of database usage in the 1960's, with the use of file based storage systems, Structured Query Language (SQL), Data Abstraction Layers (DAL) and more recently the use of Object Relational Mappers (ORM) that have now added improved opportunities for automated transaction processing. However, true data and data access portability has proved elusive due to vendor deviations from standards such as the various SQL versions plus their use of proprietary interface protocols.
This research project proposes the development of a middleware solution that we name the XML-Object Relational Mapper (XML-ORM) that acts as a Generic Transaction Based Data Access Service. The major features of the XML-ORM are;
• Providing a common and standard interface to virtual data repositories for the issuance of data access commands and return of responses via an emerging standard such as Web Services.
• Definition of an XML based standard language structure for the definition and creation of the schema, the manipulation of data and for querying and extracting the schema meta-data.
• Definition of additional transaction processing meta-data used to provide an automated transaction processing capability.
• Definition of additional multi-level hierarchical and association meta-data used to provide advanced query and analysis capability.
The XML-ORM is a middleware layer that exists between client applications and the physical database systems? all required interfacing to the physical database systems is performed by the XML-ORM system. The use of the XML-ORM system could greatly simplify the development efforts for data intensive applications such as Enterprise Information System (EIS) style applications by significantly reducing the overhead of developing database access code, with the added benefit of making EIS data simultaneously available to classes of computing devices such as mobile phones, personal digital assistants (PDA) and embedded devices that are typically unable to access proprietary database interfaces.
Ontology Based Software Engineering. The proposed research leads to the development of a new software development approach and a new concept of objects or components for interchange of code and documents over the internet. It is to facilitate multisite distributed development of corporate wide software systems. Due to the fact that current software process models and methodologies do not address the issue of collaborative multisite distributed software development environment. Most of the software process models are based on the assumption that the team doing the software development is based at a single central site. This central assumption is increasingly not fulfilled. The challenge is to develop a conceptual meta-model that will provide the architecture for the coordination of multisite software teams and the development. The objective is to find a new notion for a object or component based software development methodology; and develop a new project management approach.
