3. Motivation
•Subcontracting companies on a daily basis
•Contacts kept in Microsoft Outlook
•Colleagues share contacts via e-mail
3
Need a single database
EASY-TO-USE, SHARED, POWERFUL SEARCH

4. Requirements
•Compatible withWindows PC
•Full compatibility with Outlook Contacts
•Easy export & import from Outlook
•Powerful search engine with “advanced search”
•Attach files / customized information
•Web interface  available from anywhere

5. Explored available alternatives
•Microsoft Outlook:
• Forms and views are
rigid, not customizable
• Central information
management?

6. Explored available alternatives
•Interactions with DavidWidegren (EN/ACE/AMM)
•He suggested INFOR EAM:
•Tracking the components of structures (e.g. magnets)
• Many fields that we do not need
• Not customizable programmatically (closed source)
•QUALIAC: also not suitable
6

7. Decision
•Full stack development by open-source modules
•DB: Oracle  maintained by IT department
•Application: developed in Java by standard libraries
•Frontend: website  platform-independent
