从不清楚的数据中提取数据结构的工具 [英] tool to extract data structures from unclean data
问题描述
即:
字段:
名称:值
字段集:
nombre< FieldSet>
字段,
。
。
。
字段(n)
表
nombre< table>
头(1)...头(n)
val(1)... val(n)
。
。
。
我想知道是否有一个工具(最好在Java中)可以提取学习/理解这些数据结构,解析文件并转换为可以运行验证检查的Map或对象?
我知道Antlr,但是了解这更适合于树结构,一个不是独立的数据(我错了这个?)
有没有人对整个问题有任何建议?
我建议 Talend 。它是非常通用的开源数据集成工具。它是基于java。您可以使用构建工具/组件从非结构化数据源中提取数据。您还可以编写复杂的自定义java代码来执行所需的操作。
我在Talend的几个科学概念项目中使用了Talend。它对我有用很好的是,它是免费的!
I have unstructured geneally unclean data in a database field. There are common structures which are consistent in the data
namely:
field:
name:value
fieldset:
nombre <FieldSet>
field,
.
.
.
field(n)
table
nombre <table>
head(1)... head(n)
val(1)... val(n)
.
.
.
I was wondering if there was a tool (preferably in Java) that could extract learn/understand these data structures, parse the file and convert to a Map or object which I could run validation checks on?
I am aware of Antlr but understand this is more geared towards tree construction, an not independent bits of data (am I wrong about this?)
Does anyone have any suggestions for the problem as a whole?
I recommend Talend. It is very versatile, open source data integration tool. It is based on java. You can use build in tools/components to extract data from unstructured data sources. You can also write complex custom java code to do what you want.
I used Talend in couple of scientific proof of concept projects of mine. It worked for me. Good part is, it is free!
