问题 In Sybase PowerDesigner, when designing an UML diagram that takes 2 copies/instances of the same XXXX object (ie. objects), the application adds a number identifier like "XXXX : 2" to that symbol.

问题 I'm about to start on a new WPF application with a Sybase datastore. The team has experience with Nhibernate, but we are not really sure how well it supports Sybase and if there are some major pitfalls we should look out for. If yes, how about Fluent nhibernate? If not, do you know any other ORM products that we could use for Sybase in this scenario? Thanks. 回答1: According to this link, I would say that it does. There seems to have known issues, though.
