Abstract
Systems and methods that group atomic scalar values recognized by a database such as columns into sets (e.g., column sets). A grouping component associated with the SQL server creates a logical representation for column groupings, which are accessible by a single I/O and can be co-located (e.g., substantially close or compact) in terms of storage location. Interesting column sets (e.g., non-null) can also be selected for a data representation thereof as a single entity to other applications.
