They seem very similar to me. I don't understand the difference Maybe a programming example for ORDBMS?
回答1:
An ORM is just translation layer between objects from a programming language and relations in a relational database. It is not an RDBMS, nothing to manage a database here, just a translation / mapping layer. Read the tag info of orm.
An ORDBMS is an RDBMS with object-oriented features. This one actually manages your database. I have written more at your preceding question.
As mentioned before, those two are very different in nature.
