distribution

用电和调度等各环节的数据
power consumption and dispatching

还包括智能电网外部辅助数据
but also the development of external auxiliary data of the smart grid

开展大数据应用所需要
required for big data applications

如气象、地理信息
such as weather,geographic information

交通
transportation

人口等数据
population and other data

这些数据来源多样
These data sources are diverse

数据量大
the amount of data is large

数据类型复杂
and the types of data are complex

如何清晰掌握数据情况
How to clearly grasp the data

管理原始数据
manage the original data

加工过程数据与成熟数据
processing data and mature data

以及如何实现数据共享
and how to achieve data sharing

是智能电网大数据管理的一个基础性问题
is a basic problem for smart grid big data management

为解决以上问题
In order to solve the above problems

需要将数据作为一种资产进行管理
data needs to be managed as an asset

一方面
On the one hand

建立一套数据资产管理规范
a set of data asset management specifications is established

用制度来规范数据资产管理
and systems are used to regulate data asset management

另一方面
On the other hand

需建设数据资产管理系统，
we need to build a data asset management system

用软件进行数据资产全生命周期管理
to manage the whole life cycle of data assets with software

第二小节为管理规范
The second subsection is about the Management specifications

数据资产管理规范
Data asset management specifications

包括数据描述规范
include data description specifications

和数据流程管理规范两部分
and data process management specifications

数据描述规范是建立
The data description specification is to establish specifications

数据分类、数据编码、元数据等规范
such as data classification, data encoding, and metadata

数据分类规范是将数据分为
the data classification specification is to divide the data into major categories

电网运行、用户服务、经营管理
such as power grid operations, user services, management

电力外部数据等大类按照业务领域
and external power data according to business areas

并对大类进行二级分类
and classify the major categories into two categories

基于数据分类
Based on the data classification

参照BOM编码规范
referring to BOM coding specification

设计智能电网大数据的编码规范
the coding specification of smart grid big data is designed

对所有数据设置唯一标识
and a unique identifier is set for all data

用于追溯数据属性信息
to be used for tracing data attribute information

元数据规范是基于对数据属性的描述
Metadata specification is based on the description of data attributes

通过分析电力
By analyzing the characteristics of power

及相关数据资源特征及共享服务机制
and related data resources and shared service mechanisms

构建数据资产元数据模型
a metadata model of data assets is constructed

建立数据的描述规范
and data description specifications are established

实现对结构化数据(数据库、报表、文件、接口、视图等)
to achieve structured data (databases, reports, files, interfaces, views, etc.)

和非结构化数据的统一管理和存储描述
and unified management and storage description of unstructured data

以元模型为驱动
Driven by the meta-model

形成数据管理
form an integrated management of data management

运维、应用的一体化管理。
operation and maintenance, and application.

数据流程管理规范是
The data flow management specification is

对数据加工过程、数据接入、数据共享等进行规范
to regulate processing process, data access, data sharing, etc

形成数据加工规范
forming the data processing specification

数据入库规范
data storage specification

数据出库规范
data export specification

数据安全管理规范等
data security management specification, etc

实现对原始数据
Realize the management of original data

过程数据、成熟数据和数据共享的管理
process data, mature data and data sharing

最后一小节是关于应用程序的
The last subsection is about the application

数据分类和编码规范
Data classification and coding specifications

是数据管理的基础
are the foundation of data management

智能电网大数据涉及数据来源多
Smart grid big data involves multiple data sources

类型复杂，涉及业务也相互交叉
complex types, and related services

需要确定分类标准
It also needs to determine classification criteria

按大类对数据进行划分
divide the data according to major categories

再对数据进行细分
and then subdivide the data

基于数据分类进行数据编码
perform data encoding based on the data classification

构建数据唯一标识。
and construct a unique data identification.

数据流程管理是数据管理的核心
While data process management is the core of data management.

从数字采集
Starting from the processes of data collection

数据加工
data processing

数据入库、数据共享
data warehousing、data sharing

等流程出发
etc.

确定相应人员职责
determining the responsibilities

及操作规程
and operating procedures of the corresponding personal

从规范和系统两方面确保数据质量和数据安全
and ensure data quality and data safety from both specifications and systems

随着智能电网大数据的发展
With the development of smart grid big data
