A Rule Repository for Active Database Systems

A Repository System for Business Rules

In the last few years, rules as a new focus in systems analysis have been of increasing interest. One reason for this are recent developments in active database research which have resulted in first commercially available database management systems with active components. To support this rule-based active mechanisms, it is desirable that rules can be taken into account on the conceptual level....

Towards a Model of Concurrency to achieve Temporal Consistency in Long Duration Transaction Processing in Real Time Active Database System

This paper presents modeling of the transaction in the real time active database management systems. Active database with ECA rule has been found to provide an elegant framework to capture semantics of many real life applications. Real time database management system functions as a repository of data and provides storage and retrieval of data. Transactions, which update the database, are assign...

A Margin-based Model with a Fast Local Searchnewline for Rule Weighting and Reduction in Fuzzynewline Rule-based Classification Systems

Fuzzy Rule-Based Classification Systems (FRBCS) are highly investigated by researchers due to their noise-stability and  interpretability. Unfortunately, generating a rule-base which is sufficiently both accurate and interpretable, is a hard process. Rule weighting is one of the approaches to improve the accuracy of a pre-generated rule-base without modifying the original rules. Most of the pro...

Runtime verification of programs using rule-based active system

An Authorization Framework for Database Systems

Today, data plays an essential role in all levels of human life, from personal cell phones to medical, educational, military and government agencies. In such circumstances, the rate of cyber-attacks is also increasing. According to official reports, data breaches exposed 4.1 billion records in the first half of 2019. An information system consists of several components, which one of the most im...
