数据中台框架与实践

open access: yes大数据, 2023
数据中台将一个机构(企业、事业或政府部门)的数据作为战略资产进行管理,是从数据收集到处理应用的一套管理机制,以期提高数据质量,实现广泛的数据共享,最终实现数据价值最大化。给出数据中台的定义,提出数据中台参考技术框架,并分别对物理管理、逻辑管理、数据资产管理、数据服务和信息安全管理的组成和技术进行了展开讨论。最后以华谱系统建设为例,介绍面向家谱大数据、结合HAO智能模型的数据中台实现——华谱数据中台。

Mapping of spectral coefficients for normalized Haar transform in (0,1)coding and the transformation between to K map((0,1)编码的归一化Haar变换谱系数的图形表示及其与K图的转换)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2009
基于(+ 1, - 1)的谱技术在数字逻辑中有许多应用.为了进一步补充谱技术理论,从归一化的Haar矩阵出发,通过对矩阵的性质分析,提出了(0,1)编码的归一化的Haar变换谱系数图——R谱系数图;提出了 R谱系数图与K图的基于折叠加减的图形互换法,并举例说明了转换过程.应用表明,对5变量以下的函数该方法具有简单、直观和准确的特点.进一步完善了(0 , 1)编码的谱技术理论,有助于开拓谱技术在数字电路故障检测等方面的应用.
