PREVIOUS SYSTEM

Disadvantages:• Performance issues• Need to be installed separately to every PC

too much work at each version-release• Too complicated to add new features• Data audition could have been hard to implement• Designed to analysed only electricity data

Architecture:• Based on Java• Desktop based• Oracle database

TECHNICAL REQUIREMENTS

• Oracle database• Vertical and horizontal scalability• Easy to audit the user data changes• Web based system for the centralized version

management• Browser independency• Supporting both electricity and gas data• Use the existing export-function from the smart

reader system without much modification• Extendibility for home users for the ongoing project• Extra urgent usable beta version
