ABSTRACT:
The present invention provides for storage of data items with dissimilar structures in a single database table while minimizing the problems associated with prior approaches. In one aspect of the invention, a method of efficiently storing data items in a database management system (DBMS) is provided wherein each data item has at least one attribute associated with it, the method comprising identifying a set of attributes associated with each data item, creating, for use with all of the data items, a common data structure that excludes those attributes unique to any one of the data items, and associating each data item with attributes excluded from the data structure.
