Semi-Structured.Data
Semi-structured data lie in between unstructured and structured data. Semi-structured
data are data that has some structure, but are not rigidly structured. This type of
data include unstructured components arranged according to some predetermined
structure that can be queried using general-purpose mechanisms.
Semi-structured data is organized into entities. Similar entities are grouped together,
but entities in the same group may not have the same attributes.
