Abstract: Provided are a method, system, and article of manufacture, wherein a controller receives a request from one of a plurality of hosts. The controller determines whether a primary storage control unit coupled to the controller is operational. A response is generated by accessing the primary storage control unit, in response to determining that the primary storage control unit is operational. The response is generated by accessing a secondary storage control unit, in response to determining that the primary storage control unit is not operational, wherein data is replicated synchronously from the primary storage control unit to the secondary storage control unit.

Abstract: A method and system for providing a database as a is disclosed. In a first aspect, the method comprises the steps of accessing the database over a public network by a browser without downloading software. The method further includes controlling access to the database on an agreed-upon schedule. In a second aspect, a database service for use on a public network is disclosed. The database service comprises a presentation layer, the presentation layer including a browser, a web server coupled to the public network and a web application platform coupled to the web server. The database includes an application layer comprising a user interface (UI) application. The UI application is executed on the web application platform and is capable of communicating with the browser through a standard program code. Finally, the database service includes a database management layer. The database management layer includes at least one database which communicates with the UI application.
