July 6, 2009 — ODBMS.ORG, a vendor-independent non-profit group of high-profile software experts lead by Prof. Roberto V. Zicari, today announced that Adrian Marriott, Principal Consultant, Progress Software Inc., was awarded the ODBMS.ORG Awards for the best Common Persistent Model Patterns for Performance and/or Scalability Optimization, for his pattern “Query Visitor”.

“Query Visitor represents a query to be performed on the elements of a persistent object structure. Query Visitor allows you to define new result set formats without changing the underlying persistent object model, and avoids polluting the persistent classes with rendering logic.”, explains Adrian Marriott.

The Awards ceremony took place on July 2, 2009, at ETH in Zurich, at the evening reception of the International Conference on Object Databases (ICOODB).

Query Visitor and all 25 persistent patterns submitted are available forfree download.
