Nowadays the database of an organization is increasing day by day. Sometimes it is necessary to know the behavior of that organization by retrieving the relationships among different attributes of their database. Implication of association rules provides an efficient way of data mining task which is used to find out the relationships among the items or the attributes of a database. This paper addresses on implication of association rules among the quantitative and categorical attributes of a database employing classical logic and Frequent Pattern (FP) . Growth algorithm. The system is based on generating association rules over binary or categorical attributes and is organized with splitting the quantitative attributes into two or more intervals to generate association rules when the domain of quantitative attribute increases. The effectiveness of the method has been justified over a sample database.

Distribution of deceased person’s wealth is a divine law in Islam. This distribution should be accurate; otherwise a gruesome punishment is waiting in hereafter. The combination of relatives of late person is diverse which makes the computation of distribution difficult. In order to ease the computation of shares of slain person, a software system can be designed for Islamic Farayez which is the premier concern of this article. The existing software systems cannot compute the distribution precisely always and furthermore have lack of proper explanation of the system. Having studied ‘Islamic Shariah’ for all possible combinations of relatives of dead person, a system has been modelled and developed which provides the knowledge of Islamic inheritance and distributes the wealth of deceased accurately through which user can be galvanized to follow. Here the Islamic Farayez has been analyzed and modelled using structured approach. After fixing different scenario of Islamic Farayez of a dead person, individual cases are analysed using three levels of Data Flow Diagram (DFD). Hence, DFD illustrated the organization of the functional components of the system; and as a consequence, based on this, the graphical form of algorithm or flow-chart of the overall Islamic Farayez system is developed. Finally, mathematical models are derived for all possible combination of relatives of late person and then developed the software for Islamic Farayez system. The reliability, accuracy, integrity and robustness of the proposed Islamic Farayez system are rigorously justified by comparing the proposed system generated results with manual results as well as other existing software generated results for various complex cases. It is recommended to use this proposed Islamic Farayez system as an expert assistant for distribution of deceased person’s wealth among his/her eligible relatives.

Distribution of wealth of a deceased person among the heirs is a critical and complicated problem in Islamic jurisprudence system. In a Muslim society, the demand of a wealth calculation system is very high and plays a pivotal role in day-to-day life of Muslim families. In this paper, we propose a structured and well-defined software solution that employs structured software engineering approach using Data Flow Diagram (DFD), structure chart and program description language (PDL). The proposed system distributes shares among the heirs based on Islamic rules. Many such systems have been built by different govt agencies of different Muslim majority countries. Many of those systems are error prone and are not well defined from the software engineering perspective. In many cases, the software architecture of such systems is undisclosed and their applicability in many complex deceased-heir relationship provides wrong calculation. The proposed solution on the other hand, makes the successful use of software engineering approach to interpret Islamic Inheritance rules in a more manageable, scalable and maintainable fashion. The system is rigorously tested on different complex scenarios and the results are verified by Muslim family lawyers. The system is developed using C programming language and we make the source code open.
