Abstract: Some embodiments include utilization of a first interface to query a data source using a first configuration and to return a first data set including a plurality of records, each of the plurality of records comprising data of a plurality of fields of the first data set, and reception of the first data set from the data source. Also included may be utilization of a second interface to query the data source using a second configuration and to return a second data set for each of the plurality of records, at least one field of the second configuration being associated with one of the plurality of fields of the first data set, each utilization using the received data of the one of the plurality of fields of a respective record that is associated with the at least one field of the second configuration, and reception of a respective second data set from the data source for each utilization of the second interface.

Abstract: Some embodiments include reception of a request for data associated with an object instantiation of a component of a class model representing tag-based data and non-tag-based data, the request including user criteria mapped to a member of the component. Embodiments may also utilize an interface and a configuration to query an operational data source for data associated with data fields, wherein one of the data fields is associated with the member of the component, wherein one field of the configuration is associated with the member of the component, and wherein the one field of the configuration includes the user criteria that is mapped to the member of the component. Moreover, data associated with the data fields may be received from the operational data source and the member of the object instantiation may be populated with data of the one of the data fields associated with the member.
