- - - - DB collection of tables
      - Each table : relation
      - column: atribute
      - row: tuple
      - --> multiples properties of 1 object can cause redundunt
      - Improve :
        
        Divide a relation into smaller relations (create more tables)
        
        lossless and non - less (not lose any info)
        
        operation
        
        Select (choose rows)
        
        Project (choose columns)
        
        Join (assemble info)
        
        EX:
        NEW <-- SELECT from TABLE where Column = " "
        
        MAIL <-- PROJECT column, address from Relation
        
        NEW <-- JOIN A and B where A.W = B.X
