摘要: 随着企业业务发展以及业务数据的不断积累,数据类型参差不齐,海量数据越来越难以处理。元数据系统作为提升数据质量和数据分析的平台应运而生。元数据现已成为数据仓库以及商业智能的核心,各个厂商针对元数据系统提出了自己的解决方案。现有解决方案目前对业务数据的更新操作支持不足。针对当前元数据系统面临的随着业务数据的增加,元数据系统快速扩展支持不够,造成数据无法及时处理,以及针对元数据修改无法同步更新到业务数据中,导致元数据和业务数据不同步的问题,提出一种分布式元数据解决方案,支持系统横向扩展,同时支持通过元数据操作,反向控制业务数据。通过元数据操作,支持业务生成。

Abstract: With the development of enterprise business and the continuous accumulation of business data, data types are uneven, and massive data is becoming more and more difficult to handle. The metadata system emerged as a platform to improve data quality and data analysis. Metadata is now at the heart of data warehouses and business intelligence, and vendors have come up with their own solutions for metadata systems. Existing solutions currently do not support the operation of updating business data. In view of the increase in business data faced by the current metadata system, the lack of rapid expansion support, the inability to process data in time, and the problem that metadata modification cannot be synchronized and updated to business data, resulting in metadata and business data being out of synchronization, this paper provides a distributed metadata solution that supports horizontal expansion of the system and supports reverse control of business data through metadata operations. Support business generation through metadata operations.
Key words : metadata system;distributed system;multi data source access;application generation

隨著當(dāng)今信息技術(shù)的飛速發(fā)展以及互聯(lián)網(wǎng)技術(shù)的迅速普及,計(jì)算機(jī)技術(shù)正深刻影響著人們的生活方式。隨著企業(yè)的業(yè)務(wù)擴(kuò)展以及業(yè)務(wù)歷史數(shù)據(jù)的不斷積累,業(yè)務(wù)數(shù)據(jù)種類越來(lái)越繁雜,數(shù)據(jù)量也越來(lái)越大。需求變化大,導(dǎo)致開(kāi)發(fā)速度趕不上需求的變化速度,企業(yè)數(shù)據(jù)處理的挑戰(zhàn)越來(lái)越大。

元數(shù)據(jù)系統(tǒng)作為提升數(shù)據(jù)質(zhì)量和數(shù)據(jù)分析的平臺(tái)應(yīng)運(yùn)而生。當(dāng)前元數(shù)據(jù)系統(tǒng),主要針對(duì)特定的元數(shù)據(jù)進(jìn)行管理,對(duì)于通用元數(shù)據(jù)的接入表現(xiàn)一般。對(duì)于元數(shù)據(jù)的更新操作,很難同步更新業(yè)務(wù)數(shù)據(jù),導(dǎo)致元數(shù)據(jù)和業(yè)務(wù)數(shù)據(jù)不一致的問(wèn)題,需要業(yè)務(wù)人員手動(dòng)修改業(yè)務(wù)數(shù)據(jù)適配修改后的元數(shù)據(jù)。此舉產(chǎn)生大量的工作量,容易產(chǎn)生業(yè)務(wù)人員的錯(cuò)誤修改導(dǎo)致業(yè)務(wù)數(shù)據(jù)與元數(shù)據(jù)不同步的問(wèn)題。另一個(gè)問(wèn)題是當(dāng)前元數(shù)據(jù)系統(tǒng)針對(duì)業(yè)務(wù)數(shù)據(jù)激增,導(dǎo)致系統(tǒng)資源不足,無(wú)法做到靈活擴(kuò)展,造成數(shù)據(jù)處理不及時(shí),甚至無(wú)法處理的問(wèn)題。針對(duì)當(dāng)前元數(shù)據(jù)系統(tǒng)存在的不足,本文提出如下設(shè)計(jì)方案.
