"Relational databases are particularly good for storing highly structured information, and not particularly good at managing semi-structured data. Semi-structured data is data that has some structure, but is not rigidly structured. An example of semi-structured data is a health record. For example, one patient might have a list of vaccinations, another might have height and weight, another might have a list of operations they have had. Other examples of semi-structured data are legal documents and genealogical records... Semi-structured data is difficult to store in a relational database because it means you either have many different tables (which means many joins and slow retrieval time) or a single table with many null columns. Semi-structured data is very easy to store as XML and is a good fit for a native XML database." I think that would be a big step if we could implement a NXD in Django, but I don't speak of substitute a RDBMS by NXD else of using NXD when it was really necessary. http://www.xml.com/pub/a/2001/10/31/nativexmldb.html Some potential application areas include * Corporate information portals * Catalog data * Manufacturing parts databases * Medical information storage * Document management systems * B2B transaction logs * Personalization databases and of course for the mail addresses. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django developers" group.
