ObjectSpaces is realy good?Hey, I have been using a tool for generating persisting classes (its called
MyGeneration)...I not even use DAAB (I was rather creating my own DAAB). Now MS says ObjectSpaces is a good integrated O/RM tool, that will eliminate any needs for writing SQL queries...should I trust this ??? Cause, I am about to start a new huge project and wouldnt be happy to throw all away in the middle of the way if decision is not the right one.... What do u think about? ObjectSpaces was never delivered. Instead there will be DLinq (Linq for Sql)
in a year time or so. If you need an ORM now, I suggest a 3rd party one. -- Show quoteMiha Markic [MVP C#, INETA Country Leader for Slovenia] RightHand .NET consulting & development www.rthand.com Blog: http://cs.rthand.com/blogs/blog_with_righthand/ "Bruce One" <r***@virtualsoftware.com.br> wrote in message news:0AD611C1-0C0E-4310-AEF8-19AFBC4BC29B@microsoft.com... > Hey, I have been using a tool for generating persisting classes (its > called > MyGeneration)...I not even use DAAB (I was rather creating my own DAAB). > Now > MS says ObjectSpaces is a good integrated O/RM tool, that will eliminate > any > needs for writing SQL queries...should I trust this ???

the problem is that I use OLEDB Provider to connect either to Oracle, SQLSrv or MySQL...do u think opting for MS DAAB this would be really solved (I mean DB independency..) ?

cost something, it is very cheap. I am not against nHibernate, but it does have a steeper learning curve and requires a lot of hand work to set up the description file to create your classes. Of course, tools like MyGeneration can fill in the gap, but there is a bit of a learning curve for MyGeneration, as well (not as steep as nHibernate). -- Show quoteGregory A.
