Hello Experts!!
I have a very urgent and important task to be accomlished. Im an experienced VB Developer. Im working in a large a BANK with more than 1000 users.
Now Im assigned a task to make 3-tier application for my company. A Distributed application.
Now i need to frame my project and I need your help. I have never ever done a distibuted system ever. The condition of my project is, The Data Layer(Database) will be on a specific machine, the business layer or Middle Layer(COM) will be on a seperate machine. And the client layer which is the GUI interface will developed in Visual Basic.SO my 3-tier application will be some thing like
VB(Client) <------>COM(Business Layer)<---------->DataLaye
r(Database
SQLServer)
NOw i have no idea, how to design and develop. I can Develop the Classes, Client But i need to know how to connect the Client to the COM. as the com will be on Seperate machine and the clients on individual's machine. My problem is since i have never done such a big project I don't know how to start. I did a bit of research on 3 tier application, I came to know that people say about MTS(Microsoft Transaction Server). They ask to use and run COM on MTS. BUt AS i asid I don't know how to setup and start my project.
I have developed classes and developed GUI on single machine, as u all know that when u used a dll in the same machine, we have to add the reference in you Vbp project and specify the DLL you r using in UR machine. But here in my project the DLL will be in a seperate machine and the database will also be in a seperate machine....so how do I now do his project. I need a start and good understanding of 3-tier application.
I would highly appriciate somebody helping me urgently..PLZZ>
