Learning from AI : new trends in database technology
Recently some researchers in the areas of database data modelling and knowledge representations in artificial intelligence have recognized that they share many common goals. In this survey paper we show the relationship between database and artificial intelligence research. We show that there has been a tendency for data models to incorporate more modelling techniques developed for knowledge representations in artificial intelligence as the desire to incorporate more application oriented semantics, user friendliness, and flexibility has increased. Increasing the semantics of the representation is the key to capturing the "reality" of the database environment, increasing user friendliness, and facilitating the support of multiple, possibly conflicting, user views of the information contained in a database
Modeling of Traceability Information System for Material Flow Control Data.
This paper focuses on data modeling for traceability of material/work flow in information
layer of manufacturing control system. The model is able to trace all associated data throughout the
product manufacturing from order to final product. Dynamic data processing of Quality and Purchase
activities are considered in data modeling as well as Order and Operation base on lots particulars. The
modeling consisted of four steps and integrated as one final model. Entity-Relationships Modeling as
data modeling methodology is proposed. The model is reengineered with Toad Data Modeler software
in physical modeling step. The developed model promises to handle fundamental issues of a
traceability system effectively. It supports for customization and real-time control of material in flow
in all levels of manufacturing processes. Through enhanced visibility and dynamic store/retrieval of
data, all traceability usages and applications is responded. Designed solution is initially applicable as
reference data model in identical lot-base traceability system
Access Control and Service-Oriented Architectures.
Access Control and Service-Oriented Architectures" investigates in which way logical access control can be achieved effectively, in particular in highly dynamic environments such as service-oriented architectures (SOA's). The author combines state-of-the-art best-practice and projects these onto the SOA. In doing so, he identifies strengths of current approaches, but also pinpoints weaknesses. These weaknesses are subsequently mitigated by introducing an innovative new framework called EFSOC. The framework is validated empirically and preliminary implementations are discussed.
A Catalog of Reusable Design Decisions for Developing UML/MOF-based Domain-specific Modeling Languages
In model-driven development (MDD), domain-specific modeling languages (DSMLs) act as a communication vehicle for aligning the requirements of domain experts with the needs of software engineers. With the rise of the UML as a de facto standard, UML/MOF-based DSMLs are now widely used for MDD. This paper documents design decisions collected from 90 UML/MOF-based DSML projects. These recurring design decisions were gained, on the one hand, by performing a systematic literature review (SLR) on the development of UML/MOF-based DSMLs. Via the SLR, we retrieved 80 related DSML projects for review. On the other hand, we collected decisions from developing ten DSML projects by ourselves. The design decisions are presented in the form of reusable decision records, with each decision record corresponding to a decision point in DSML development processes. Furthermore, we also report on frequently observed (combinations of) decision options as well as on associations between options which may occur within a single decision point or between two decision points. This collection of decision-record documents targets decision makers in DSML development (e.g., DSML engineers, software architects, domain experts).Series: Technical Reports / Institute for Information Systems and New Medi
