How do I save the data entered in Windows C Forms into a SQL database?
To save data entered in Windows C Forms into a SQL database, you can use ADO.NET to establish a connection to the SQL database and then use SQL commands to insert the data into the database tables. First, establish a connection to the database using SqlConnection class, then create a SqlCommand object with the SQL INSERT statement to insert the data into the database. Finally, use the ExecuteNonQuery method of the SqlCommand object to execute the SQL INSERT statement and save the data into the SQL database. Make sure to handle any exceptions and properly close the connection after the data has been saved. **
What are the 2nd and 3rd normal forms?
The 2nd normal form (2NF) requires that a table be in 1NF and that all non-key attributes are fully functionally dependent on the entire primary key. This means that there should be no partial dependencies, where a non-key attribute is dependent on only a part of the primary key. The 3rd normal form (3NF) requires that a table be in 2NF and that all transitive dependencies are removed. This means that non-key attributes should not be dependent on other non-key attributes. In other words, every non-key attribute should be directly dependent on the primary key. Overall, both 2NF and 3NF are aimed at reducing data redundancy and ensuring that the data is organized in a way that minimizes anomalies and inconsistencies. **
