We could make some cross-reference queries to look for domain administrators that have the Password never expires attribute set (a part of the userAccountControl attribute).
The ascertainment of the core attribute set of large database is an important process of generating the classifying rules.
The attribute set then forms a blueprint that guides the phases of analysis, design, coding, deployment, maintenance, update, and so on.
Then the membership matrix obtained by clustering algorithm was used to reduce attribute set. Finally, based on entropy, a knowledge acquisition method of fuzzy Rough Set (RS) was put forward.
Each attribute works with one or more of the attribute sets.
