13. A computer-implemented method, comprising: providing a first user interface configured to enable selection from a plurality of business event query template types from a user; receiving selection of a business event query template type from the plurality of business event query template types, the selected business event query template type comprising a Key Performance Indicator (KPI) alert template; generating the selected business event query template type by: identifying a set of one or more query parameters related to the selected business event query template type, the set of one or more query parameters comprising at least one KPI measure that identifies a critical metric of an organization, and the at least one KPI measure specifying an aggregation on a column of a data object in the KPI alert template; determining a set of one or more threshold parameters specifying one or more threshold conditions for the set of one or more query parameters; and defining an alert event to be transmitted to the user when a value associated with a query parameter exceeds a threshold condition specified by the set of one or more threshold parameters associated with the at least one query parameter; upon the generation of the selected business event query template type, determine, from a set of input data source types, one or more compatible input data source types usable with the selected business event query template type based at least in part on actions associated with the selected business event query template type, the set of input data source types including a stream type data and a relation type data; providing, via the first user interface, based at least in part on the received selection, the KPI alert template; providing, via a second user interface, the set of one or more query parameters associated with the selected business event query template; receiving, via the second user interface, a value associated with the at least one KPI measure from the set of one or more query parameters from the user; receiving, via the second user interface, a user-selected input data source type of the one or more compatible input data source types; providing, via a third interface, the set of one or more threshold parameters for the at least one KPI measure, the set of one or more threshold parameters specifying the one or more threshold conditions for the at least one KPI measure; receiving, via the third user interface, one or more values associated with the set of one or more threshold parameters for the at least one KPI measure from the user; generating a continuous query based at least in part on the set of one or more query parameters, the set of one or more threshold parameters, and the business event query template, the continuous query configured to provide the alert event when the value associated with the at least one KPI measure exceeds the threshold condition specified by the set of one or more threshold parameters associated with the at least one KPI measure; receiving a request to save the generated continuous query; generating an extensible markup language (XML) file configured to enable subsequent generation of the continuous query; storing the extensible markup language file; and execute the continuous query on an input data source of the user-selected input data source type to retrieve the business event data associated with the user.
13. A computer-implemented method, comprising: providing a first user interface configured to enable selection from a plurality of business event query template types from a user; receiving selection of a business event query template type from the plurality of business event query template types, the selected business event query template type comprising a Key Performance Indicator (KPI) alert template; generating the selected business event query template type by: identifying a set of one or more query parameters related to the selected business event query template type, the set of one or more query parameters comprising at least one KPI measure that identifies a critical metric of an organization, and the at least one KPI measure specifying an aggregation on a column of a data object in the KPI alert template; determining a set of one or more threshold parameters specifying one or more threshold conditions for the set of one or more query parameters; and defining an alert event to be transmitted to the user when a value associated with a query parameter exceeds a threshold condition specified by the set of one or more threshold parameters associated with the at least one query parameter; upon the generation of the selected business event query template type, determine, from a set of input data source types, one or more compatible input data source types usable with the selected business event query template type based at least in part on actions associated with the selected business event query template type, the set of input data source types including a stream type data and a relation type data; providing, via the first user interface, based at least in part on the received selection, the KPI alert template; providing, via a second user interface, the set of one or more query parameters associated with the selected business event query template; receiving, via the second user interface, a value associated with the at least one KPI measure from the set of one or more query parameters from the user; receiving, via the second user interface, a user-selected input data source type of the one or more compatible input data source types; providing, via a third interface, the set of one or more threshold parameters for the at least one KPI measure, the set of one or more threshold parameters specifying the one or more threshold conditions for the at least one KPI measure; receiving, via the third user interface, one or more values associated with the set of one or more threshold parameters for the at least one KPI measure from the user; generating a continuous query based at least in part on the set of one or more query parameters, the set of one or more threshold parameters, and the business event query template, the continuous query configured to provide the alert event when the value associated with the at least one KPI measure exceeds the threshold condition specified by the set of one or more threshold parameters associated with the at least one KPI measure; receiving a request to save the generated continuous query; generating an extensible markup language (XML) file configured to enable subsequent generation of the continuous query; storing the extensible markup language file; and execute the continuous query on an input data source of the user-selected input data source type to retrieve the business event data associated with the user. 15. The computer-implemented method of claim 13 , further comprising processing the user data based at least in part on the generated continuous query, wherein processing the user data includes at least receiving the user data from a stream or based at least in part on a relation.
