Databases

Can someone explain how C# uses databases and what SQL is used for? How does one store data into a database in C#?

How do I connect to a database in C# and what are the the options available. Thanks

SQL is the language of databases. Instructions written in SQL for the database are called "queries". One option in C# is to use library calls to establish a database connection and pass queries directly to the database.

But a much more elegant option is to use "Entity Framework". This maps database tables into model objects and makes it easy to read and update the database. There are several Treehouse courses that teach Entity Framework programming.

It's good to know SQL no matter what language you normally program in, so you can interact directly with the database when needed.

But you won't need SQL when you develop with Entity Framework. It lets you handle your database through C# objects and it takes care of the SQL behind the scenes for you. EF is definitely the way to go for database access in C#.
