In Lesson 3, we discussed a fully connected mode of operation for interacting with a data source by using the Sql Command object.

In Lesson 4, we learned about how to read data quickly an let go of the connection with the Sql Data Reader.

During the day, they’ll make modifications to existing customer data, add new customers, and input new orders.This is okay because they have a given region or customer base where other people won’t be changing the same records.At the end of the day, the sales person will connect to the network and update changes for overnight processing.Execute Non Query(); sql = "insert into highscores (name, score) values ('Myself', 6000)"; command = new SQLite Command(sql, m_db Connection); command.Execute Non Query(); sql = "insert into highscores (name, score) values ('And I', 9001)"; command = new SQLite Command(sql, m_db Connection); command.

Since we’re working in C# we’ll be using the System. All you’ll need are two files, a and a file for some documentation. Every time you interact with the database, you’ll need to provide the connection object.
