Abstract
A computer implemented system, program product, and method that organizes hierarchical data into a plurality of columns is disclosed. A schema interface is defined for the data and two types of columns, value columns and occurrence columns, are used. Each value column stores the values for a field. Each occurrence column stores the occurrence numbers for a node that is repeatable, or optional, or in a choice group. The hierarchical relationship of the data is jointly preserved by the schema interface and the occurrence numbers in the occurrence columns. A database management system built upon the method is capable of operating at higher efficiency by combining some of the best aspects of relational database and hierarchical database management systems. The computer implemented method also provides a new and efficient method of exchanging data over networks.
