Abstract
This invention pertains in general to data management, and in particular to a system and method of storing in one relational database consisting of at most five physical tables, data from an arbitrary number of arbitrarily designed relational schemas. The addition and deletion of schemas and the modifications of existing schemas do not affect the structure of the database itself. The present invention is an ideal storage system for data aggregations with a quickly evolving data model (for example, moveable and customizable components within moveable and customizable components), data aggregations with practically unbounded sets of entities and attributes (for example, intelligence data about customers, contacts, and competitors), and data aggregations that do not assume prior knowledge of the data schema (for example, self-describing data aggregations like XML documents).
