如前所述，使用XML数据库的价值(相对于CLOB或分割为关系数据)是改进性能，提高xml精确度，以及简化开发。
As described above, the value of using an XML database (as opposed to CLOBs or shredding into relational data) is increased performance, XML fidelity, and simplified development.
分割拓扑距离在总体上可反映树间的拓扑结构差异，但其测度精确度比通经拓扑距离要低。
The partition topological distance can by and large measure the difference between phylogenetic trees, but has lower accuracy than the pathway topological distance.
