What is your experience working with database management systems?

Experience with database management systems (DBMS) typically includes:

• Designing and creating databases using SQL (e.g., creating tables, indexes, relationships).
• Writing queries for data retrieval, insertion, updating, and deletion.
• Optimizing queries and indexes for performance.
• Working with transactions and ensuring data integrity.
• Using ORM (Object-Relational Mapping), such as Entity Framework in C#, to interact with the database through objects.
• Configuring database connections from applications.

Example of a simple C# query using ADO.NET:

using System.Data.SqlClient;

string connectionString = "your_connection_string";
using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();
    string query = "SELECT * FROM Users WHERE Age > @age";
    SqlCommand command = new SqlCommand(query, connection);
    command.Parameters.AddWithValue("@age", 18);

    using (SqlDataReader reader = command.ExecuteReader())
    {
        while (reader.Read())
        {
            Console.WriteLine(reader["Name"]);
        }
    }
}

Such experience enables effective work with data in C# applications.
