Data reorganization

The data reorganization involves operations by which a data can be arranged in a new way. They do not create a new data, but they only organize the data. There are three major cases:

• The operations arrange information in data frames.
• The operations arrange information in classified data frames.
• The operations arrange information in data frames related to classified data frames.

• Transpose of a data frame
• Joining data frames
• Indexing through a joining operation
• Finding unique data records
• Finding unique indexes from classes
• Finding the indexes of the classified data from another classified data
• Merging a grouping and a classified data
• Picking data records based on a classified data
• Binarizing a classification to a data
• Sorting a data
• Classifying a data by the BMU classifier
• Classifying data records to sequencies
• Concatenating sequencies
• Overlapping sequential data sets
• Set operations for classes
