    Oh, va bene, ho capito che conoscete la lingua tedesca, ma questo a noi interessa poco; anzi, niente :p

    The "stupid tables" have to main purposes:

    1) represent an "object"
    2) allow you to perform searches, filtering and associations/relations (via non-stupid queries).

    Saving a complex object, in binary format or xml/json text does not have the same usefulness.

    a table represent some data of a "object" and split everything in tables with links between is terrible and then if you need all for a report u need long querys.

    object databases can also have indexing and a search.
    sql querys are text, uncheckable and raise run time erros. means if u rename a field in db, if u wrote names wrong in sql etc.

    if u can save a whole class/object with all sub objects it have much usefulness. u not need a db table/field mapping. u not have a db struct.

    So, if you had an object that represents a customer's purchase order for a product, you save this complete object, rather than having several tables (Customer, Order, Item,...).
    By saving the whole object, you will have precisely what the normalization avoids: redundancy.

    i never saw a object database, i guess it save each object separately and each object have also an primary key.
