- All users of the portal have secure inbox access wherein they are notified about account activities/admin change actions/application statues. These emails should be saved as PDF documents.
- Authorized persons should be able to view/edit the static web content of the application as and when required.
Challenges:We needed one solution to fit all above requirements. We knew the content size would grow with time. The key points which we considered:
- A system with strong security.
- A scalable solution to meet future requirements.
- A system which can be easily integrated with existing Java application.
Solution: After analyzing available ECMs we figured out Alfresco was able to cater to all these requirements and was a cost effective solution. With following features, Alfresco stood as a solution encompassing all our requirements.
- Alfresco guarantees content safety through its security model which is comprised of authentication and authorization.
- Alfresco One-Enterprise edition is highly modular and scalable.
- We could easily integrate Java application with Alfresco using its OpenCMIS extension which depends on Apache Chemistry OpenCMIS libraries.
Now that we have seen how useful alfresco is, let‚Äôs see the thing to look out for while using Alfresco.
Though alfresco meets most of the requirements there are few limitations of this ECM as per different users.
- The system lacks backup capabilities.
- Its support system needs improvement in Live chat and FAQ sections.
- Few of the UI features can be automated and provide better user experience.
