Design 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...

مقدمه 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...

Multi-dimensional clustering for data base organizations

A Kernel Design for a Secure Data Base Management System

The need for reliable protection facilities, which allow controlled sharing of data in multi—user data base management syst~ms. is steadiLy orowing. This paper first discusses concepts relevant to such protection facilities, including data security. object granularity, data independence, and software certification. Those system characteristics required for reliable security and suitable functio...
