    • A relationship-information storage unit stores relationships between configuration items. The configuration items belong to an information system and are stored in multiple databases. A first counting unit compares, across the databases, attribute values of one configuration item in each of the databases, thereby counting a matching-attribute-value count. A second counting unit identifies a configuration item having a relationship with the one configuration item, for which the first counting unit counts the matching-attribute-value count, by referring to the relationship-information storage unit. Then, the second counting unit compares, across the databases, attribute values of the identified configuration items to count a matching-attribute-value count. A similarity calculation unit calculates similarity between the configuration items, based on the matching-attribute-value count counted by the first counting unit and the matching-attribute-value count counted by the second counting unit.
    • 关系信息存储单元存储配置项之间的关系。 配置项属于信息系统,存储在多个数据库中。 第一计数单元在数据库中比较每个数据库中的一个配置项的属性值,从而对匹配属性值计数进行计数。 第二计数单元通过参照关系信息存储单元来识别与第一计数单元对匹配属性值计数进行计数的一个配置项的关系的配置项。 然后,第二计数单元跨数据库比较所识别的配置项的属性值,以对匹配属性值计数进行计数。 相似度计算单元基于由第一计数单元计数的匹配属性值计数和由第二计数单元计数的匹配属性值计数,来计算配置项之间的相似度。
