Axapta vs Navision
For those involved in MS Business Solutions, or those just wondering about the difference between two of Microsoft's important business solution products - Axapta and Navision, the following (annotated) post by Gerrit Combrink and Rene on the Microsoft.Public.Axapta newsgroup might be helpful:-
The focus areas of both products are around Manufacturing, Distribution and Services. The main differences are with functionality and technology.
(In Axapta, all this functionality is standard. There is no standard Services functionality in Navision. Such functionality needs to be built by ISVs.)
Axapta is aimed more towards the top end Mid market to corporate customers with complex requirements, while Navision looks after the lower to middle mid market segment with less complex requirements.
(Lower meaning: about 10 concurrent users. Above 20 users: Axapta)
Technology within Axapta also allows it to be a much stronger, more stable, higher performing competitor in a 3-tier environment as this is built into the existing architecture. You can also run a lot more concurrent users on a Axapta system than on Navision.
(Axapta's AOS technology (Axapta Object Server) provides scalability. Axapta has been tested from 1 user up to 3500 concurrent users.)
