I try to build a simple 3-Tier Application in VB .net but it isn't working as i want it to, even when following tutorials.
Therefore i would Need a very Basic 3-Tier Database Application with a step-to-step Explanation on how it is build.
I use the visual Studio community Edition.
Steps to be included:
1. Class library (Buisness object): Create edmx Modell using the designer. Just add two tables:
1. Artikel (id: (prime key, autogenerate, int32), Artikel_name: String)
2. Shop(id:(prime key, autogenerate, int32),, Artikel_id: (int_32) , Shop_name)
2. Class library (Data Access Layer): Here i would only Need one class:
Artikel_manager (implements idisposable).
public function getAllArtikel() as list (of Artikel)
Returns all Artikel from table Artikel
The third Tier for the displaying of the data is not neccessary to implement.
I hope the description is clear. Otherwise please fell free to contact me.
