Reality Beschreibung: Wir haben eine Liste von Projekten. In jedem Projekt gibt es viele Konten. Sie können viele Aktionen für jedes Konto ausführen. Ich habe folgende Dimensionen und Faktentabelle definiert (vereinfacht):OLAP - Berechnen Sie Run-Off-Dreiecke, Beispieldaten und Würfel enthalten (PostgreSQL/Mondrian)
Dimensions and attributes:
Project
project_key
project_name
industry
number_of_accounts
Distance
distance_key
distance_in_months
distance_in_quarters
Account
account_key
project_key
account_id
Fact Table and attributes:
Action_Fact_Table
project_key
distance_key
account_key
action_id
Nun würde Ich mag Run-off-Dreieck Ansatz verwenden, um Daten zu analysieren (es ist vielleicht nicht das eigentliche Abwicklungsdreieck, aber der Ansatz ist dasselbe). Das einfachste Dreieck würde folgendermaßen aussehen:
Es läuft die Summe der Anzahl der Aktionen nach Zeilen. Distanz in Monaten zeigt die Entfernung zwischen Datum der Aktion und Projektstartdatum. Sie können natürlich ein ähnliches Dreieck erstellen, indem Sie die Entfernung in Vierteln (oder jeder anderen in der Abstandsdimension definierten Periode) verwenden.
Sie können auch Triangel für verschiedene Hierarchieebenen in der Projektdimension erstellen, z. Industrie (Project1-Project3 = Branche1, Projekt4-Project5 = Branche2):
Distance in Months
Project name| 1 2 3 4 5 6 7 8 9 10
-------------------------------------------------------------------------
Industry1 | 14 29 44 59 74 92 109 126 108 50
Industry2 | 5 14 23 30 39 53 40
Es gibt auch fortgeschrittenere Abwicklungsdreieck, wo Sie Summe der Maßnahmen durch die Anzahl der Konten unterteilen ausgeführt wird. Angenommen, es ist die folgende Anzahl von Konten für unsere Projekte:
Project_name number_of_accounts
-----------------------------
Project1 100
Project2 100
Project3 100
Project4 100
Project5 200
Dann würde Ich mag das folgende Dreieck erhalten:
Distance in Months
Project | 1 2 3 4 5 6 7 8 9 10
------------------------------------------------------------------------
Project1 | .05 .01 .15 .20 .25 .30 .35 .40 .45 .50
Project2 | .7 .14 .21 .28 .35 .42 .49 .56 .63
Project3 | .2 .5 .8 .11 .14 .20 .25 .30
Project4 | .0 .2 .5 .10 .18 .23 .40
Project5 | .05 .06 .09 .10 .105 .15
Dies ist besonders nützlich, wenn Sie Projekte vergleichen möchten und ihre Aktionen wenn die Anzahl der Konten im Projekt nicht für alle Projekte gleich ist.
Die Frage ist, ob es möglich ist, eine solche Berechnung in OLAP zu erstellen. Ich dachte, ich könnte number_of_accounts in der Projekttabelle verwenden, aber ich kann es nicht herausfinden. Die andere Option besteht darin, Daten in der Kontodimension zu aggregieren. Ich konnte auch nichts mit Google finden, vielleicht weil ich eine falsche Frage stelle.
Die Lösung dieser Frage ist in vielen Branchen weit verbreitet, vor allem im Versicherungs- und Bankwesen. Es kann überall dort eingesetzt werden, wo Prozesse ein langes Leistungsfenster haben und durch genau definierte, vergleichbare Chargen von Einheiten verfolgt werden können.
(Wir verwenden PostgreSQL, Saiku, Würfel in Schema Workbench definiert sind)

Gut hören Sie Fortschritte machen . Ich vermute, dass das Fehlen von Antworten darauf zurückzuführen ist, dass Sie auf dem neuesten Stand eines etwas unbekannten Technologie-Stacks sind. –
@MikeHoney Könnte obskure Technologie sein, aber die Frage ist generisch - lassen Sie uns wissen, wenn Sie Antwort für MS-Technologie oder andere wissen. –
Ich würde wahrscheinlich die RunningValue-Funktion in SSRS (Reporting Services) verwenden –
