A Hierarchical Access Model for Data Base Organizations
A generalized mu1ti-dimensional model for physical data base organizations is presented. Existing data base organizations are shown to easily fit into the model as special cases. Generalized retrieval algorithms and cost equations associated with the model are developed and analyzed. The model provides a general design framework in which the distinguishing properties of data base organizations ...
متن کاملمقدمه ای بر: تکنولوژی data base و اداره سازمان
در ادراه امور سازمان نیز از تکنولوژی data base در دو زمینه مشخص یعنی بصورت سیستم های عملیاتی و سیستم های اطلاعاتی میتوان استفاده کرد. در شرایط کنونی وجود موانع متعدد از قبیل فرهنگ غالب در سازمان های بزرگ و طرز تلقی مدیران دیوان سالار از یکطرف و تازه گی و پیچیده بودن فنون مربوط به سیتم های data base فقدان دانش، تجربه و تخصص کافی برای بهره گیری کامل از آن از طرف دیگر، برنامه ریزی و اقدام برای ایج...
15 صفحه اولHierarchical Structure for Data Management
on a hierarchical organization of the data management control function and makes use of list processing concepts. Discussed are the separation of the logical and physical control functions as well as the data-element and operating-system controls. This hierarchical approach establishes a common basis for the creation, maintenance, and retrieval of data in direct-access storage. Logical function...
متن کاملDesign of a Multiplier for Similar Base Numbers Without Converting Base Using a Data Oriented Memory
One the challenging in hardware performance is to designing a high speed calculating unit. The higher of calculations speeds in a computer system will be pointed out in terms of performance. As a result, designing a high speed calculating unit is of utmost importance. In this paper, we start design whit this knowledge that one multiplier made of several adder and one divider made of several su...
متن کاملA Survey on Duplicate Detection in Hierarchical Data
Although there has been a lot work done on identifying duplicates in relational data, but only a few solutions focus on identifying duplicates in more complex hierarchical structures, like XML data. In this paper, we have demonstrated the novel method for XML duplicate detection, called XMLDup. XMLDup method implements the Bayesian network to calculate and determine the probability of two XML n...
