Documentum Vs Sharepoint

1. Sharepoint 2007 is tightly integrated with Office 2007. Documentum has some light integration with Office through Webtop Application Connectors. Documentum has stronger integration with other authoring applications including Dreamweaver, QuarkXPress, and Adobe InDesign.
2. Sharepoint provides various mechanisms to access and modify content when offline (eg Outlook, Access, etc). Documentum only supports offline editing if you install Documentum Desktop application.
3. Sharepoint 2007 supports rights management with Office 2007 natively. Documentum requires you to install Information Rights Manager to have this feature.
4. Both Documentum and Sharepoint provide the ability to create custom object types. However, Sharepoint’s object model does not seem to support object inheritance.
5. Lifecycle features (eg applying actions, defining entry criteria, applying lifecycle to multiple documents, etc) is more extensive in Documentum than in Sharepoint.
6. Documentum security model is more extensive than Sharepoint. Documentum has extended permissions that allow users to perform specific functions (eg change ownership, change state, change permissions, etc).
7. All objects in Documentum are secured using the security model. In Sharepoint only certain objects can be secured (eg web site, list, folders, documents, etc).
8. Content can be only published to Sharepoint site; however, if content needs to publish outside of MOSS repository, this requires custom coding. Content can be published to any website using Documentum Site Caching and Site Delivery Services. Documentum also has portlets for various portal vendors that allow those portals to access content that is stored in Documentum repository.
9. The obvious - Sharepoint only runs on Windows using Microsoft SQL Server. If you are enterprise standard is UNIX/Linux or Oracle/DB2, then Sharepoint is not a valid option. Documentum is OS and database agnostic. Documentum is supported on various OS and database configurations.
10. The next obvious – Sharepoint is built on ASP.NET; thus, customizations are done via .NET framework. Documentum is built on DFC, which is built on Java. You should consider the development and support skills of your staff when considering which system to choose.
11. Content Storage - Sharepoint stores content within the SQL Server database. This allows Sharepoint to utilize SQL Server native search capabilities. This also means that backup of content is solely dependent on backing up of the database. Documentum stores content on a file storage system and content metadata in any database. This architecture allows for multi-server single docbase configuration. Since content is stored on file system, you can also create a mix storage architecture composed of SAN, NAS, RAID, tape, etc
