Maintaining Data-driven Rules in Databases using an Invariant Based Language
نویسندگان
چکیده
A data-driven rule is a rule that is activated as a result of modiications of data items in a database. Data-driven rules become very useful in applications that use a combination of rules and DBMS technologies. This paper presents the considerations in choosing an adequate programming style for representing data-driven rules based on software engineering aspects, namely, ease of use in a high-level language and better veriiability of the rule language. We show that contemporary database programming styles fail to provide the required tools and present the invariant based language as an adequate tool for representing data-driven rules.

Today, the need to deal with ambiguous information in semantic web languages is increasing. Ontology is an important part of the W3C standards for the semantic web, used to define a conceptual standard vocabulary for the exchange of data between systems, the provision of reusable databases, and the facilitation of collaboration across multiple systems. However, classical ontology is not enough ...

متن کاملConcordance-Based Data-Driven Learning Activities and Learning English Phrasal Verbs in EFL Classrooms
In spite of the highly beneficial applications of corpus linguistics in language pedagogy, it has not found its way into mainstream EFL. The major reasons seem to be the teachers’ lack of training and the unavailability of resources, especially computers in language classes. Phrasal verbs have been shown to be a problematic area of learning English as a foreign language due to their semantic op...
متن کاملA Data-driven Method for Crowd Simulation using a Holonification Model
In this paper, we present a data-driven method for crowd simulation with holonification model. With this extra module, the accuracy of simulation will increase and it generates more realistic behaviors of agents. First, we show how to use the concept of holon in crowd simulation and how effective it is. For this reason, we use simple rules for holonification. Using real-world data, we model the...
