In order to create an application in Visual Basic .NET like Payroll System, Accounting System, Enrollment System, Calculator, Point of Sale System, and Library System you need to create a project called “Windows Application”.

If you are new to programming and want to learn Visual Basic, you will probably confuse with so many option to choose in starting a Visual Basic Editor.

Please look at the screen below.

Actually i saw a question at  the forum:

Sometimes you want to transfer or backup your database in SQL Server. When the database is attached you cannot copy/move it to any location. All you have to do is detach it first using SQL Server Management Tools.

Another reason why I write this tutorial is to teach you so that when we finish the Library System project you will be able to switch from my own database to your own database just in case you want to differentiate each of the table.

To attach a database

1. Open SQL Server Management Tools.

2. Right click Database and click Attach.

In my previous tutorial I discuss on “How to Add Table to Your Existing Database”. Now, I will explain to you on how to create database relationships between one or more tables. Relationship is very important to prevent data inconsistency in your database. For example, you cannot add record in the related table without first adding a record in the primary table.

A relationship exists when two tables are related using a primary key and a foreign key.
