Abstract: One or more visible user interface controls from a cache can be displayed. The user interface controls can also include one or more virtualized controls and one or more partially visible controls. In response to an indication to move in a dimension, one or more displays of visible user interface control(s) can be changed, and a control can be virtualized in the cache. Also, in response to the indication to move, one or more of the user interface controls in the cache can be recycled by performing population (i.e., populating the control) with data from outside the subset of data items in the data set. Additionally, an indication to change the number of controls in the data set can be received, and in response, the number of controls in the cache can be changed.

Abstract: A configuration management database for storing configuration information about an IT system. The configuration management database may have representations of configuration items that correspond to configuration items in the IT system, indicia of relations between the configuration items, and attributes of the configuration items. The configuration management database may also have configuration state information of the configuration items, where the configuration state information has information indicating whether a configuration item, relation, or attribute is in a state of pending approval or in a state of planned deployment. The configuration management database may also have temporal information indicating a temporal state of a configuration item, relation, or attribute.
