About the features of POSTGRES Resent-To: postgres-redist@postgres.Berkeley.EDU Resent-Date: Fri, 04 Nov 94 13:26:03 -0800 Resent-XMts: smtp Hi, dear netter: I'm a new user of POSTGRES and have been testing it for several weeks. I'm also evaluating a OODB, Objectivity, but I'm not understand whether the POSTGRES support some features as described in OODB, such as long duration transation nested transaction shared transaction schema evolution version control dynamic binding and Polymorphism Besides these features, basically the POSTGRES is an extended relation database, what's its performance compared with a real object-oriented database? Are there some general rules to compare these two different type of databases? Any guidance or comment is much appreciated.
