对于数据，使用JSON：如果您拥有结构化或半结构化的数据，那么选择JSON。
JSON for data: If you have structured or semi-structured data, choose JSON.
原始数据可以是结构化的，也可以是半结构化的，甚至是分布在网络上的异构型数据。
Raw data can be structured, it can also be a semi-structured, even distribution on the network of heterogeneous data.
更为复杂的问题是，大量需要处理的数据是非结构化或者半结构化的，这就更难查询了。
Further compounding the issue is that a lot of the information needing to be processed is either unstructured or semi-structured text, which is difficult to query.
