Data Classification and Data Clustering
 
 Grading
The grading mainly depends on class distribution.
The chart below is the grading criterion using a data classification.
 
 
 Data Mining: Data Classification
The process finds the common properties among a set of objects in a database and classifies them into different classes, according to a classification model. 
 
 
 
 Information Retrieval: Data Clustering 
 
The process of grouping physical or abstract objects into classes of similar objects is called clustering or unsupervised classification.
