  • structured data : Structured data is best known as relational data, but is any text based data stored in such a way that enables it to be accessed and queried to an agree standard. For relational data, its stored in a well defined mathematical structure with official rules and standards for accessing and manipulating it. Other types of databases storing text data exist and conform to different standards. Any data that is not stored in a well defined structured format can by default be seen as unstructured. The traditional view is that unstructured data is just any binary data. There is a fuzzy area between structured and unstructured, more akin to saying there are degrees of structure and there is a lot of overlap. It's possible to store unstructured data in a column in a relational table, which is structured. (†628)
  • structured data : Any data stored in a well defined, non propriety system. Data is primarily text based. Typically conforms to ACID. (†630)
  • unstructured data : Unstructured data can be broken down into different groups. A well known group is multimedia or rich media. Here there are types like digital image, audio, video and document (though there are more in this list). Some of these types are well defined and can contain embedded in them XML (or other) that conform to an agreed set of standards. The format of the binary data can also follow agreed rules. The digital image format JPEG is an open standard. For video, MPEG is also an open standard. Multimedia would be a category of unstructured data that is well defined. Its category is fluid and changing as technology changes and unlikely will ever be able to conform to the mathematically and well proven relational structure. (†629)
