Database Management Systems
This class is about Database Management Systems. As such we talk about creating, managing and programming SQL databases. When time permits, we also cover spatial/spatial temporal data and database systems. This site contains content developed by Dr. Anderson for his classes.
2011 Winter Class
Programming Examples
- Lecture 1: It really easy that easy to do small things
Commandline Connected Example
Forms Disconnected Example
- Lecture 2: Look at the Objects we used in the Forms from Lecture 1.
Filled by TableAdapter contained in the TableAdapterManager
BindingSource as a service provider
- How are GUI elements bound then?
- How do the GUI elements change?
- Lecture 3: Detail Tables, Validation and other GUI Objects
- What you bind to makes all the difference.
- Responding to the Validating Event
For anything other than small, independent projects consider the Entity Framework with LINQ.
Programming & Design Resources
Learning to program something more complex than a one off programming assignments for students can be difficult. Where do the experts learn to program large database applications and what tools and methods do they use? This section is not an answer, but a suggestion on where to look for those answers. Someday, I hope to have a class that explores this in depth.
DBDesigner is an awesome tool that went for pay by oracle now. Get the old one and don't pay for the ability to reverse engineer a diagram from a database. Works with Oracle, MSSQL and MySQL.
Link Pad allows you to write scratch c# LINQ code and claims it can be used as a drop in replacement for SQL Server Management Studio
And many more to follow I'm sure.
