A System for Querying and Viewing Business Constraints
نویسندگان
چکیده
In E-commerce processes, various rules and constraints regarding product specifications, pricing, terms and conditions are exchanged between vendors and buyers. Developing a formal model for those rules and constraints gives a foundation for new E-commerce applications. Our approach is to develop a constraint database holding these conditions as dynamic constraints and provide a query language, called dynamic constraint algebra (DCA), for retrieving and matching business constraints. In this paper, we describe a system for processing DCA queries, its system architecture, constraint language, and graphical user interface for interactively querying over a database containing pricing and combination rules of products.

Assembly line balancing to minimize balancing loss and system loss
Assembly Line production is one of the widely used basic principles in production system. The problem of Assembly Line Balancing deals with the distribution of activities among the workstations so that there will be maximum utilization of human resources and facilities without disturbing the work sequence. Research works reported in the literature mainly deals with minimization of idle time i.e...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملQuerying Process Models Repositories by Aggregated Graph Search
Business process modeling is essential in any process improvement project. Yet, it is a time consuming and an error-prone step. With a rapidly increasing number of process models developed by different process designers, it becomes crucial for business process designers to reuse knowledge existing in model repositories, e.g., to find solutions for a recurring situation. Process model querying p...
متن کاملA High Performance System for Viewing, Querying, and Retrieval of Geospatial Data Distributed Across a Beowulf Cluster
The size of many geospatial databases has grown exponentially in recent years. This increase in size brings with it an increased requirement for additional CPU and I/O resources to handle the querying and retrieval of this data. A number of proprietary systems could be ideally suited for such tasks, but are impractical in many situations because of their high cost. On the other hand, Beowulf cl...
متن کاملIdea: Efficient Evaluation of Access Control Constraints
Business requirements for modern enterprise systems usually comprise a variety of dynamic constraints, i. e., constraints that require a complex set of context information only available at runtime. Thus, the efficient evaluation of dynamic constraints, e. g., expressing separation of duties requirements, becomes an important factor for the overall performance of the access control enforcement....
