Databases

Databases are structured systems designed to store and manage data efficiently. In this course, we work with XAMPP, which uses the MySQL database, and SQL Server Management Studio, which provides access to SQL Server. These tools offer different options for data management, querying, and security. XAMPP is ideal for web application development as it includes both Apache Server and MySQL, while SQL Server Management Studio is suited for managing larger and more complex databases. Database management systems ensure data is secure, accessible, and efficiently processed.

SQL Server Triggers

A trigger is an object in a database that acts automatically when a specific event occurs on a table, such as when data is added (INSERT), modified (UPDATE), or deleted (DELETE).

A trigger is bound to a specific table and contains an SQL statement or block that is executed when a specified condition is met.
