What is the best and fast ORM to use with Oracle for .NET ? Based on your evaluation , experience etc. (to replace my existing data layer for oracle)
fast = operations per second
best = lest time to learn and does not have any high fi mumbo jumbo
Need to load 10,000 or more records and update them in 10 mins or less... on oracle.
Define "best" and "fast". Are you looking at learning curve (i.e. fast to learn), performance, speed of development once you know what you are doing with it? Are you looking for distributed cache support or anything non-standard? There are always edge cases where you can make a non-ORM solution slightly faster than an ORM solution, so if you are really looking for "fastest", do you even want an ORM in the first place?
If you're relatively new to ORMs, then NHibernate has good community support, including Fluent NHibernate to help with the learning curve. But we'd need to know more about your real priorities to make a firm recommendation.
