hello
I have a question
if for example I have an application in aspnet 4.0, in 4 layers: presentation, business, data and entity, but would like to make another system but consume business layers, data and system entities I have already ...
My new system will be in another team, necessarily would have to create a web service layer with WCF or asmx, for web service to connect to the logic of the first system, either my new system made in NET or other technology, as my webservice returns xml,
which is a standard that means: net, java and php ..
I would recommend enterprise level, to have a single database on a server;
server where they are and my web service layer, business logic, data layer and entities, this server would have all the functionality of the company,
and my systems on other servers that consume my services application server, which queries my database only ....
...
Go to the complete details ...
