In 2007 the technique was being used in a few data warehouses and one OLTP system, and it was presented internationally by Lars Rönnbäck at the 2007 Transforming Data with Intelligence] (TDWI) conference in Amsterdam.This stirred enough interest for the technique to warrant a more formal description.
It provides a graphical notation used for conceptual modeling similar to that of entity-relationship modeling, with extensions for working with temporal data.In order to handle changes in the information content anchor modeling emulates aspects of a temporal database in the resulting relational database schema.The earliest installations using anchor modeling were made in Sweden with the first dating back to 2004, when a data warehouse for an insurance company was built using the technique.The Under Secretary of Commerce for Intellectual Property and Director of the United States Patent and Trademark Office advises the Secretary of Commerce and other federal departments and agencies on intellectual property policy matters.Over 6 million patents have been issued since the first patent in 1790 and 2.3 million trademarks have been registered since the first in 1870.For more information, see the patent database on the Web at
USPTO, a user fee-funded agency of the United States, within the Department of Commerce, administers laws relevant to granting patents and registering trademarks.
