Hi, Setup your inventory database in a separate system(server), and configure the database to allow remote connections. Now you have to modify your connection string, connection string needs to be pointed the database in the server.
Data Source=127.2.3.4\SQLEXPRESS,1433;Network Library=DBMSSOCN;Initial Catalog=database_name_here;User ID=user_id_here;Password=password_here
Data Source=127.2.3.4\SQLEXPRESS,1433;, in this line,
127.2.3.4 - denotes the server IP address.
SQLEXPRESS - denotes the database server instance.
1433 - denotes the server port number.
After setup of the database server, you can use your application in any PC inside the LAN, and it will connects the database in the server as per the connection string.
