Introduction
This is a Skills International School, and they sought to enhance their operations by developing
a comprehensive database system. Hence, we are undertaking the task of creating this database
system to meet their needs.
In this database project, we are utilizing Visual Studio alongside an SQL Database
Management System.
• Visual studio
Figure 1 visual studio.
Visual Studio is an integrated development environment (IDE) created by Microsoft. It is used
for developing applications, websites, web services, and mobile apps. Visual Studio supports
a wide range of programming languages, including C#, VB.NET, C++, Python, and JavaScript,
among others. It provides a comprehensive suite of tools and features that facilitate coding,
debugging, and deploying software.

• SQL Database Management System
Figure 2SQL Server Management Studio
An SQL Database Management System (DBMS) is a software application that uses Structured
Query Language (SQL) to manage and manipulate relational databases. SQL is the standard
language for querying and managing data in a relational database, which organizes data into
tables with rows and columns.
