Abstract
A method of and system for managing cached data across disparate systems is disclosed. A system for providing cached data coherency includes: a client computer, an application server, a main database, one or more remote application servers, and a communication network interconnecting the client computer, the application server, the main database, and the one or more remote application servers. The application server being operable to respond to a data record being updated by the client computer, by: updating a cache local to the application server, updating the main database, generating a command object defining the updating of the data record, and sending the command object to the one or more remote application servers. The one or more remote application servers being operable to respond to the receipt of the command object by executing the command object, thereby storing the updated data record on caches local to the one or more remote application servers.
