Aspects of the present disclosure relate to enhancing reading retention of users reading electronic text. A set of user data associated with a user currently reading electronic text on a device is received, the set of user data indicative of a reading retention of the user. The set of user data is analyzed to determine whether a retention enhancement action should be issued. In response to a determination that a retention action should be issued, the retention enhancement action is issued at the device the user is currently reading electronic text on.

Memory retention enhancement for electronic text

Processing data of a data warehouse is provided and includes receiving, by a processing device, user input to create simple filter objects. Each filter object defines an ad hoc subset of a respective dimension of a dimension table of the data warehouse. User input is received to create a filtered operation object that specifies an operation and a plurality of the simple filter objects. The ad hoc subset differs from all subsets defined in the dimension table.

Processing data in a data warehouse

Data of a database environment, which includes hierarchy information and a matrix of values, is processed. The hierarchy information includes at least two sets of identification codes and defines at least two groups of identification codes. The matrix of values includes at least two columns of identification values. At least one simple filter object is generated based on a user input. Each simple filter object defines an ad hoc group of identification codes selected from a respective one of the sets of identification codes. A filtered operation object that specifies an operation and at least one of the simple filter objects is generated based on a user input. Each of the ad hoc groups differs from each of the groups defined by the hierarchy information.
