Unfortunately, the literature on B-trees is not uniform in its use of terms relating to B-Trees. (Folk &amp; Zoellick 1992, p. 362)&nbsp;Bayer &amp; McCreight (1972), Comer (1979), and others define the order of B-tree as the minimum number of keys in a non-root node. Folk &amp; Zoellick (1992) points out that terminology is ambiguous because the maximum number of keys is not clear. An order 3 B-tree might hold a maximum of 6 keys or a maximum of 7 keys. (Knuth 1998,TAOCP p. 483) avoids the problem by defining the order to be maximum number of children (which is one more than the maximum number of keys).&lt;\/span&gt;&lt;\/span&gt;&lt;img

in its use of terms relating to B-Trees. (Folk &amp; Zoellick 1992, p. 362)&nbsp;Bayer &amp; McCreight (1972), Comer (1979), and others define the order of B-tree as the minimum number of keys in a non-root node. Folk &amp; Zoellick (1992) points out that terminology is ambiguous because the maximum number of keys is not clear. An order 3 B-tree might hold a maximum of 6 keys or a maximum of 7 keys. (Knuth 1998,TAOCP p. 483) avoids the problem by defining the order to be maximum number of children (which is one more than the maximum number of keys).<\/span><\/span><img loading=\"lazy\"
