Integrating alfresco with existing infrastructure
We have many custom and off-the-shelf applications to manage document mgmt like scanning, indexing, storage,workflow etc in our company,

We want to get started with Alfresco to completely manage our document management process.
This requires integration with external databases, interfacing with existing Java infrastructure and internal Oracle DB.
Since there is huge amount of information for Alfresco on the web, i want to know how do we go ahead with Alfresco. Any specific tools of Alfresco i should be using and how easily can i revamp our existing process with Alfresco.   
Please advise.
