    I was doing an AQA COMP3 past paper, and one of the answers uses the term 'TO', does anyone know what this abbreviation means?

    The markscheme said:
    Implementation details using a composite key:
    Create a new field CopyID;
    Composite key formed by BookID and CopyID; TO if composite key is clearly in book table or loan table
    Store the BookID and the CopyID in the new table; R adding CopyID to Book table as this would created data redundancy but this does not talk out other mark scheme points
    Add the CopyID field to Loans table; R replace BookID with CopyID

    I'm not familiar with the subject, and it doesn't seem to list it on the first/second page of mark schemes - but would it make sense to stand for 'Turn Over'?
