I’m evaluating O/R Mappers for a fairly large ERP system where reliable technology is a major concern.

Hopefully, those of you reading this post don’t find that that requirement contradict using LLBLGen Pro instead of DataSets and MS Data Access Application Block or the like.

I’d like to get in touch with everyone with good, or bad, experiences since it’s impossible for me under given circumstances to use any ORM tool that hasn’t been proven in real life enterprise applications.

Hi

We use LLBLGen on a fairly big databases according to me.

SQL Server 600 + Tables 1800 + Stored Procs 60 + UDF's DB Size 60 GB - 100 GB

LLBLGen is very fast, in execution speed of the SQL statements and speeds up development time rapidly. One of the best things about this product is the support. Frans is always there - between 7 am - 12 pm (GMT +02:00) and one of the other best things is the $ price. $ There is always updates with new features comming out. We have not experienced any bugs with the system yet.

The product is also very customizable: 1. You can customize the class names. 2. You can alter the class templates to generate the code for you exactly as you want it. 3. There is an SDK so developers can develop their own Task performers. 4. You can use Task performers developed by other developers.

One of the limitations that i found was that LLBLGen does not have a component \ Class where you can inject SQL into to get a result, everthing is very strongly typed (A good thing) and the only other way that i know of to acheive something simular is by creating a typed view. This type of control is usually usefull with reporting.

The LLBLGen technology is very reliable - my only concertain as a user of this technology is what do i / we do when something terminal happens to Frans? But i guess the only thing that will happen in that sinario is that there won't be any more updates or future versions so we would have to keep on using the existing LLBLGen - and it is stable enough and advanced enough to work well into the future.

Overall we are very happy with what LLBLGen offers and we are sure that Frans will continue his good work into the feature - Just hope he does not sell out to Micro$oft.

I just got started using LLBLGen Pro about a month ago and, while there has been a small learning curve, I couldn't be happier! Once I got comfortable using the generated code, I easily shaved 20-30% off the typical effort. As mentioned above, the price is great and support couldn't be better!

Heck, I'm suprised they still let me on these forums for all the questions I've asked. THREE CHEERS FOR LLBLGEN!
