I am new to Documentum, I have to upgrade one code from Documentum foundation class to Documentum Foundation Services. Can someone provide the pros and cons of each, and good source of information to get started with it.
btw, I am writing code in Java to get information from documentum.
IMHO they are not comparable because they are not focused on the same. DFC is an API to access Documentum while DFS is a service framework with some predefined services providing some functionality to interact with Documentum.
Thats important: I never used DFS :-)
DFC = Do-it-yourself. Traditional Client-Server programming. Faster.
DFS = Use predefined services or do it yourself for non-trivial tasks. SOA. Probably you need to deploy your services in a new server or purchase more Documentum licenses (not sure about that). Slow but I will feel more comfortable using this if I want to access Documentum from some legacy systems.
Thats my grain of salt I hope you find it useful.
DFS is the new age API for Documentum ( built on the web services concept). You need to read the documentation for DFS which is pretty explanatory. In addition to this you need to have a basic understanding of web service calls (exposing a service, WSDL, building remote clients).
