A computing system for providing a plurality of aggregated KPI-values of a plurality of KPIs (KPI1, . . . , KPI40), from a server processing device to one or more views of a GUI of at least one client processing device, comprising:
- the client processing device, the client processing device being a mobile, hand-held electronic appliance, the client processing device comprising:
- a touch-screen for displaying the one or more views,
- an application program,
- means for receiving log-in data of a user, and
- a first database, the first database comprising a first table for storing O-aggregated KPI-values, each O-aggregated KPI value being calculated for one organization node of an organization graph and for one of the KPIs by aggregating KPI values of said one KPI being respectively assigned to said one organization node or to any of its direct or indirect child nodes,
- means for receiving the log-in data of the user by the application program,
- means for identifying one organization node of the organization graph as the organization node representing the logged-in user and using said identified node as current organization node,
- the server processing device, the server processing device being operatively coupled to a second database, wherein the second database comprises a copy of said organization graph, the server processing device comprising:
- a plurality of web-service interfaces being accessible by the application program, each interface being operable to receive and process a request for one or more of the plurality of KPIs being particular to said interface, each interface being operable to return an aggregated KPI value read from the second database, wherein the second database comprises a further first table for storing O-aggregated KPI-values, each O-aggregated KPI value being calculated for one of the organization nodes and one of the KPIs by aggregating KPI values of said one KPI being assigned to said one organization node or to any of its direct or indirect child nodes, wherein the application program is operable to execute the steps of:
- A) determining one or more first KPIs for the current organization node;
- B) accessing the first table of the first database for retrieving O-aggregated KPI values for one or more first KPIs for the current organization node,
- C) in case the O-aggregated KPI values could not be retrieved from the first database, determining from the plurality of web service interfaces one or more first web-service interfaces being operable to receive and process a request for the first KPIs,
- D) querying the determined first web service interfaces via a network for receiving the O-aggregated KPI values of the first KPIs,
- E) storing the O-aggregated KPI values received from the second database in the first table of the first database,
- F) displaying the O-aggregated KPI values retrieved from the first database or received from the second database in an organization view, the organization view displaying the current organization node and its direct child organization nodes, the organization view enabling the user to navigate within the organization graph, whereby a selection of one of the displayed organization nodes triggers the re-execution of the steps A-F, wherein the selected organization node is used as the current organization node.
