I have been asked by many people to differentiate Documentum and Sharepoint. For a detail analysis, I have always recommended that customers contact Gartner and other like firms that can truly perform a competitive analysis. That being said, I think I can at least identify some obvious architectural differences that might aid potential customers who have to choose one platform.
- 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.
- 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.
- 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.
