<h2>简介</h2>
|
||||
<p>
|
||||
Haflow是一个,以组件为设计单位的,具有拖拽式流程设计界面的,可以协同异构数据分析工具的,分布式的,服务化的,易用性高的,可扩展性强的,开放式的大数据分析服务平台。
|
||||
</p>
|
||||
<p>
|
||||
<strong>从前端来看,</strong>开发人员通过拖拽和关联组件,完成整个分析流程的设计。开发人员还可以通过组件管理界面发布自定义的组件,或者导入一组面向领域的可复用组件。整个客户端体现很强的易用性和可扩展性。

|
||||
</div>
|
||||
<p>
|
||||
<strong>从后端来看,</strong>大数据服务平台构建在分布式集群上,并且集成多种数据处理,分析和挖掘工具,并发地调度执行各个分析任务。前端通过调用后端系统提供的Restful API来完成前后台的通信。
|
||||
</p>
|
||||

|
||||
</div>
|
||||
<p>
|
||||
<strong>从数据分析工程师的角度来看。</strong>该平台可以屏蔽各个系统和工具的异构性,降低数据分析的难度,加快信息提取的速度。
|
||||
</p>
|
||||
<p>
|
||||
<strong>从企业成本的角度来看。</strong>首先,大数据分析平台可供多个用户同时向集群提交多个流程。通过对这些多个流程的调度,不仅可以降低流程的平均执行时间,并且可以极大地提高了集群的利用率。其次,拖拽式的开发极大的降低了对分析人员专业技能的要求,使得分析人员可以从算法编写,实验脚本编写等繁杂工作中抽离出来。帮助企业缩短决策的时间,改进决策的过程。
|
||||
</p>
|
||||
<p>总之,大数据分析服务平台不仅可以缩短公司投资回报周期,同时也可以提高公司投资回报率。</p>
