- Performance Impact: Consider how it affects performance and scalability.
- Resource Availability: Ensure there are enough resources (time, budget, skills) for adoption.

4. Describe a situation where you implemented a new DBMS feature or technology in your project. What was the impact?

Answer: An example could be the adoption of JSON data storage features in PostgreSQL to support a project requiring flexible data models. This feature allowed the team to store unstructured data more efficiently, reducing the need for complex joins and improving query performance.

Key Points:
- Problem Identification: The need for more flexible data storage options.
- Solution Implementation: Utilizing PostgreSQL's JSON capabilities.
- Outcome Measurement: Improved performance, simplified queries, and increased developer productivity.

Example:

// Example of storing JSON data in PostgreSQL using Npgsql in C#
using (var conn = new NpgsqlConnection(connectionString))
{
    conn.Open();
    using (var cmd = new NpgsqlCommand())
    {
        cmd.Connection = conn;
        // Storing a JSON object
        cmd.CommandText = "INSERT INTO my_table (data) VALUES (@p)";
        cmd.Parameters.AddWithValue("p", NpgsqlDbType.Json, "{\"name\": \"John\", \"age\": 30}");
        cmd.ExecuteNonQuery();
    }
}

This example demonstrates how a specific DBMS feature can be applied to address project requirements, showcasing the importance of staying updated on advancements in database technologies.
