Today businesses have to change the way that they operate frequently because of advances in technology and business-to-business communication. To be able to keep up with these changes in business operations it is necessary to separate business rules and procedures from system functionality. By defining a component-based business model, it is possible for the business expert to specify and modify business operations without re-designing the automated system controlling the business operation. We propose a business model consisting of three different components where domain expert in each area can define and customise a component with minimum interaction with other components of the business model. Our main objective behind the component-based approach in business model specification is twofold. One is to be able to define a model that is easily customisable by domain expert, eliminating the need to develop a new system when changes to the business process or organisation have been introduced. Secondly this approach will reduce the time, cost and disruption to the business. We have mapped this model to an XML representation which best can describe the hierarchical and semi-structural format of business model. A system for B2B communication has been developed using this approach.
objectoriented methods are now popular in many areas of computing, increasingly so in those areas associated with analysis and management science. The first system to incorporate many of the ideas of object orientati...

Component-Based Software concepts have been arousing a great deal of interest in recent years. Due to their effectiveness in the design and development of software applications and due to their many advantages in terms of reusability, components can also be applied in database design. This paper aims to present a component-based approach to database systems. Components are introduced as logical partitions of the schema, a corresponding ODL extension being proposed. The paper also tackles transaction processing in terms of scope, which can now escalate component-wise up to the level of the entire schema. The main benefits are the reusability of the database design and a smooth information exchange. The integration of crosscutting concerns into the component database model using aspect- oriented techniques is also discussed.
Ultrahigh areal density is the key target of hard disk drive technology. Hence, writing field strength from head and switching field, Hsw, of media should be improved. In this work, we propose the one of alternative m...
