Open the CIPO recordAbstract From the Canadian patent
A system that uses an object to relational database mapping infrastructure to map C++ objects and their relationships to and from a relational database. The mapping is facilitated by mapping files which describe an object and how the object corresponds to a table in the database. Overflow tables are provided in the database when an object is associated with more than a predetermined number of other objects, such as two. A C++ reflection layer allows access to attributes and methods of C++ objects at run-time by name. Mapped data is also memory buffered during the transferring of data to and from the database.

Why it's free to use
- Filed July 26, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 26, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 26, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
