U.S. PATENT NUMBER 5,617,567
Data processing system and method for retrieving an entity specified in a search path from a relational database
- Effective Filing Date: May 21, 1990

Method to assemble and execute inquiries between entities and relationships without programming.
The Prior Art required software developers to develop complex code to handle their application’s specific relationship query requirements. This locked their code to a specific data model design inside hand coded programs - which was both a time consuming and error prone methodology.
Today, many products provide flexible query facilities, linking several tables together in a single query. This often produces extremely inefficient and long running SQL code. The patented IP allows new queries to be constructed that join several tables but that execute with higher performance. An API to this query facility allows traditional programs to inherit this flexibility.
