Abstract
A technique is provided for accessing data stored in separate databases. A communication system having a first and second computer system is used to retrieve data from a primary or a secondary database. The primary and secondary databases are coupled to the first computer system. A data access controller is used in the system to automatically shift the first computer system from retrieving data from the primary database to retrieving data from the secondary database. The data access controller shifts when a communication error between the primary database and the first computer system is detected by the system.
Claims34
A communication system, comprising:
- a first computer system;
- a primary database coupled to the first computer system;
- a secondary database coupled to the first computer system;
- and
- a data access controller to automatically shift the first computer system from retrieving data from the primary database to retrieving data from the secondary database when a communication error between the primary database and the first computer system is detected by the system.
A communication system, comprising:
- a first computer system;
- a primary database coupled to the first computer system;
- a secondary database coupled to the first computer system, wherein data in the primary database is stored in a first format and data stored in the secondary database is stored in a second format;
- and
- a data access controller to automatically shift the first computer system from retrieving data from the primary database to retrieving data from the secondary database when a communication error between the primary database and the first computer system is detected by the system.
A communication system, comprising:
- a first computer system;
- a medical imaging system coupled to the first computer systems;
- a primary database coupled to the first computer system;
- a secondary database coupled to the first computer system;
- and
- a data access controller to automatically shift the first computer system from retrieving data from the primary database to retrieving data from the secondary database when a communication error between the primary database and the first computer system is detected by the system.
A data access controller, comprising
- a computer program stored in a tangible medium, the computer program being operable when stored in a first computer system to direct the first computer system to verify communication with a primary source of data accessible via a second computer system and to direct the first computer system to access data from a secondary source of data when communication between the primary source of data and the first computer system is not verified.
A method of operating a communication system, comprising the acts of:
- storing a first set of data in a primary database stored in a first computer system and storing a second set of data in a secondary database;
- coupling an application to one of the primary database and the secondary database via a data access controller stored in a second computer system, the data access controller being configured to normally couple the application to the primary database;
- verifying communication between the second computer system and the primary database;
- and
- automatically operating the data access controller to couple the application to the secondary database when communication between the second computer system and the primary database is not verified.
A method of operating a communication system, comprising:
- storing a first set of data in a primary database stored in a first computer system and storing a second set of data in a secondary database, wherein the first set of data is stored in a first data format and the second set of data is stored in a second format, further wherein automatically operating the data access controller comprises changing the mode of operation of the data access controller from transferring data in the first format to transferring data in the second format;
- coupling an application to one of the primary database and the secondary database via a data access controller stored in a second computer system, the data access controller being configured to normally couple the application to the primary database;
- verifying communication between the second computer system and the primary database;
- and
- automatically operating the data access controller to couple the application to the secondary database when communication between the second computer system and the primary database is not verified.
A method of retrieving data comprising:
- storing a first database in a first computer system;
- coupling a second computer system to the first computer system via a data access controller and a network;
- retrieving data from the first computer system via the data access controller and thenetwork;
- and
- retrieving data from a second databases via the data access controller when communication via the network is lost.
