En metod för utveckling av en skalbar och komponentbaserad larmcentralsklient. (Swedish)
Abstract [en]

Different methods are compared to examine different possibilities to develop an alarm centre client with high scalability. Methods for the construction of a component and methods to handle the communication between components in the system. Also the possibility to create a robust and stable system with high performance was investigated by comparing and evaluating different techniques. Techniques to validate data and secure the client from communication interruptions.

A client with high scalability can efficiently be developed by using a component based model where each component is created with support from the .NET base class library, components which can be developed and tested independently. The data validation technique is highly dependent of the update frequency and the present data type. A Query Notification technique was chosen for irregularly updated data and a Pollningtechnique for regularly updated data.

Abstract [sv]

Olika metoder jämförs för att utreda hur man effektivt kan utveckla en skalbar komponentbaserad larmcentralsklient. Metoder för att konstruera en enskild komponent samt för att hantera kommunikationen mellan olika komponenter i ett sammansatt system. Vidare studeras hur man med olika tekniker kan skapa ett robust och stabilt system, samt tekniker för att validera data och säkra klienten mot avbrott i kommunikationen.

En skalbar klient kan utvecklas genom att man använder en komponentbaserad modell där man använder .NET’s klassbibliotek för att skapa sina komponenter vilka kan utvecklas och testas oberoende av varandra. Valet av valideringsteknik var högst beroende av hur ofta en viss typ av larmcentralsdata uppdaterades i databasen. Effektivast visade det sig vara att använda en notifieringsteknik för validering av data med en oregelbunden uppdateringsfrekvens och att använda en pollningteknik för regelbundet uppdaterad data.
