When loading data into a table, it splits into two groups 2 16 rows are further decomposed into individual data packets for each of the columns. By separating each column with the same number of rows, it retains its integrity with the other speakers to the same record. Each data packet is separately compressed to about 10: 1 on average.
A layer of metadata (the so-called Knowledge Base, Mesh) retains a compact information about the content and the relationship between the data packets, replacing the traditional concept of a database index.
The optimizer uses the theory of rough set and granular computing categorizing what data should be extracted taking the necessary information from the Knowledge Base
