    How to define a primary key for non-relational files

    Question

    How to define a primary key for NON-relational files

    Answer
    The attached (primarykey.xml) is an example of the correct way to define the primary key for a table e.g. NATION. Note that the key and primary
    key are two different things.
    Declaring a primary key will not affect the Query Processing, so a key must be defined as well.
    The primary key is just a declaration which is reported to external tools.
