Visuelle Analyse von stored procedures in Datenbanksystemen

Abstract

In vielen großen Datenbanksystemen kommen Stored Procedures zum Einsatz, wenn es um die effiziente Verarbeitung der Daten geht. Diese bilden nach einiger Zeit ein schwer zu überblickendes System aus komplexen Abhängigkeiten. Fehleranalysen und Optimierungen sind dann nur noch mit hohem manuellem Aufwand und intensiver Kenntnis des Systems möglich. In dieser Diplomarbeit wird ein interaktives System zur visuellen Analyse von Stored Procedures entwickelt. Der aktuelle Stand der Verarbeitung, zeitliche Verzögerungen sowie die Abhängigkeiten der Stored Procedures sind in der Visualisierung unmittelbar ersichtlich. Mit diesem Werkzeug kann der Anwender leicht den Prozess über viele Stored Procedures verfolgen und einfach Lastspitzen sowie Leerläufe identifizieren. Außerdem können wichtige Metriken statistisch analysiert werden. Der entwickelte Prototyp wird mit Hilfe von Experteninterviews evaluiert.

In many big database systems Stored Procedures are used to efficiently transform the data. Over time these procedures become a difficult system with complex and obscure dependencies. Analyses of failures and for optimization purposes can only be done with huge manual effort and in-depth knowledge of the system. In this thesis a new interactive system for the visual analysis of Stored Procedures is proposed. The current status of processing, delays and the dependencies are directly visible in the visualization. Using this system, the analyst can easily trace the process across many Stored Procedures and find load peaks and idle states. Statistical analysis of important metrics of the processing is also directly possible. The prototype of the system is evaluated using interviews with database specialists.
