A system for use-case software development includes an interface renderer for interpreting a user interface definition code and displaying a user interface, a request dispatcher for processing a request from the interface renderer, and a request handler for processing the request and checking a use-case name contained in the request. The system further includes a use-case handling program, invoked by the request handler, for performing logic defined by a use-case corresponding to the use-case name and according to a use-case state and returning an interface definition specifying an interface layout and controls that are interpretable by the interface renderer, and a server page container for receiving the interface definition and providing the user interface definition code to the interface renderer.

A method for detecting security intrusions and soft faults in a software system includes receiving a multi-dimensional performance signature built from operating system metrics sampled by a software system monitoring infrastructure, associating a plurality of buckets with each component of the performance signature, comparing a component of the sampled performance signature to an expected value for the performance signature component, where a bucket for the performance signature component is incremented if the sampled performance signature component exceeds the corresponding expected value, and the bucket for the performance signature component is decremented if the sampled performance signature component is less than the corresponding expected value, executing a security alert notification when the bucket for the performance signature component exceeds a first threshold, and executing a soft-fault notification when the bucket for the performance signature component exceeds a second threshold, where the first threshold is less than the second threshold.

A configuration operation set for configuring a system element is tested by simulating execution of the control operation set with simulation sample test data. The configuration operation set is received via a configuration user interface in a configuration view. Simulation sample test data is received via a simulation user interface in a simulation view. The configuration view and the simulation view may be simultaneously viewed on a display. In a single session, a control operation set may be received, simulation sample test data may be received, a simulation may be run, and the results of the simulation may be viewed. If the results of the simulation agree with expected results, the control operation set may be saved, and executed in the system element of interest. If the results of the simulation do not agree with the expected results, the control operation set may be cancelled.
