I'm Developing my own EDMS using Oracle 8i
You know that a product like Documentum took over a man-century to create, right?
How about some details on the type of EDMS?
Well, I would start by downloading 10g, enterprise edition, and buy a license, as you will need the advanced features:http://www.google.com/url?sa=U&start=1&si=...base/oracle10g/
Then use Oracle*Text, if you can afford the licenseing costs.
Else, you will have real issues with LIKE searches inside the table rows. . . .
reasons about the front end of EDMS
I would use HTML-DB myself, easy concurrency management:http://www.dba-oracle.com/oracle_tips_free...concurrency.htm
I would also look at Oracle application server 10g with HTML-DB:http://www.dba-oracle.com/oracle9iAS_tips_...ml_db_10gas.htm
