Weapon firing solutions, status reports, commands to another system, or outgoing E-mail could be counted as EOs. One exception to this rule is that all operator-requested retrievals of information from any combination of ILFs or EIFs that do not contain any derived or calculated information are counted as EQs and not as EOs. DETs are usually unique, user-recognizable, nonrepeating fields or attributes, including foreign key attributes, that exit the boundary of the subsystem or application. FTRs, or more simply files referenced, total the number of ILFs read or referenced and the external interface files read or referenced by the EO transaction. External Inquiries External inquiries identify unique operator trigger or response, i.e., question or answer, combinations that retrieve stored data without any mathematical calculation.
EQs are usually common retrieve, view, extract, display, browse, or print functions.
Typical examples might include a view of the current location of a target, a digitized map image, an event report or log, a view of incoming mail, the retrieval of voice or fax messages, a display of a user profile or current operational settings, diagnostic data, help messages, parameter settings, or system status. Retrievals of data upon operator request from any combination of ILFs or EIFs that contain any derived or calculated information are counted as EOs and not as EQs. Values for each file and transaction category are calculated using the standard weights shown in Table 2 to determine the total unadjusted function points for the subsystem. Characteristics such as redundancy, complexity, communication, distributed processing, and security are recognized in this part of the process. Distributed data processing.
